The story: In 2000, chemical engineer and climate scientist Adam Lowry joined forces with Eric Ryan, an account planner in advertising, to create a line of home care and personal care products that were non-toxic and made with naturally-derived, biodegradable ingredients. But they didn’t stop there. Instead, they made it their priority to “fight dirty” in a larger sense, including offsetting carbon emissions, designing products that meet Cradle-to-Cradle environmental designs standards, using natural materials and making pet bottle washing line manufacturer from 100 percent recycled plastic.

Today, Method is frequently cited as one of the fastest growing and most innovative companies with more than 100 different product SKUs in 35,000 retail locations throughout the US, Canada, UK, France and Australia.

The challenge: Launched nine years ago, the brand’s iconic dish soap developed a loyal following; but as much as people loved what was inside the pet bottle washing line, they were often frustrated by the bottle itself. “Method has been offering a great dish soap that cleaned the dishes really well in a natural and biodegradable way, but what people were dissatisfied with was the entire category,” says Michelle Arnau, Method brand manger, cleaning business. “Upright, squeezable dish products intuitively don’t make sense, because your hands are slippery and wet when you are washing dishes,” she says. “And so to pick something up, [frequently] results in you dropping it.”

Method decided to take a step back, look at how people were doing their dishes and redesign its pet bottle washing line manufacturer accordingly.

The solution: Before designing any prototypes, Method conducted hours of in-home ethnography (watching people do dishes). After studying various dish-washing methods, the brand found that, whether they poured soap directly into a pot, on a dish or on a sponge, people were coming up with workarounds to make the process easier and more enjoyable.

“We realized that consumers wanted something different, but they didn’t know what,” Arnau says. “So we decided that this was the ideal time, instead of just bringing minor improvement to the old [tear drop-shaped] dish pet bottle washing line, to come up with something that was truly breakthrough.”

The result is a new specialized pump that does not leak or clog. Inside the pet bottle washing line manufacturer, the dip tube is angled to the very bottom, enabling it to soak up all the liquid. The bottle is also ergonomically designed with a wider base and the pump is formed with a ridge at the top that prevents slippage.

In order to prevent product confusion, the brand made sure to have familiar visual cues on the product. The front of the pet bottle washing line says, “Method Dish Soap,” and can still be found in the brand’s best-selling fragrance, cucumber. “Sometimes we like to get creative with our [product] names, but with this product in particular, because we were taking away a product that people did like, it was important that they had a great cue of, ‘Ok, this is the same great thing, just in a new package,’” Arnau says.

Like most of Method’s products, the bottles are made of 100 percent recycled plastic, pet bottle washing line manufacturer in this case. The bottle is also the brand’s first Cradle-to-Cradle certified product in the dish category, and the very first C-2-C dish soap in the world.

The results: The new packaging rolled out at the beginning of August, and while it’s early, the brand says it is excited about the preliminary sell-ins, as well as consumer and retailer feedback

 

pipe extrusion line

According to one aspect of the present invention, a roll assembly for guiding a pipe in a pipe extrusion line for producing pipes of different diameter, includes a bracket, a roll supported by the bracket, and an adjustment device for automatically positioning the roll in vertical direction in dependence on a weight load upon the roll.

The present invention resolves prior art problems by so constructing a roll as to adjust its vertical position in dependence on the weight load acting on the roll. Hereby, the invention is based on the recognition that pipes of greater diameter normally have a greater weight per meter. Thus, when the roll is loaded by a pipe of greater weight, and thus normally also of greater diameter, the roll moves further downwards than would be the case, when the weight load on the roll is smaller as a result of a smaller pipe and thus of smaller weight. Thus, when being exposed to a smaller pipe, the roll moves upwards in opposite direction. In this way, the center line for pipes of different diameter can still be maintained at substantial same vertical height in a simple manner.

The roll is rotatably mounted on an axle which is supported indirectly or directly by an elastic element that forms the adjustment device. A plurality of materials and devices known per se may be used as elastic element, such as, e.g., rubber-like elements. Currently preferred is the use of a spring, in particular a spiral spring, as elastic element, for movably supporting the axle so as to allow the roll to move downwards as a load on the roll increases. Suitably, the spiral spring has a spring hardness which is suited to a weight per meter range of the pipe which range correlates with the dimension range. Thus, the roll for guiding the pipes aligns itself spontaneously to the weight load.

According to another feature of the present invention, the roll assembly includes a plurality of such rolls which are arranged in succession, whereby the rolls may have varying roll geometries. For example, rolls may be used which correspond to a maximum pipe radius. The rolls may also be constructed in such a way as to laterally support also the smallest pipes to be produced. Such pipes are preferably arranged in the area of the vacuum tank. The subsequent spray baths may use roll geometries which are configured in the form of a double-V-block so that the pipe is guided also in this case always on both rear sides.

According to another aspect of the present invention, a pipe extrusion line for producing pipes with different diameter includes an extruder for plasticizing a starting material to produce a melt strand, an adjustable calibration device sizing the melt strand to shape for forming a molten tube, a cooling device for cooling the tube, and a roll assembly for guiding the tube during advance through the calibration device and the cooling device, wherein the roll assembly includes a plurality of rolls arranged behind one another in a travel direction and constructed to have at least two different roll geometries, and an adjustment device for automatically positioning the rolls in vertical direction in dependence on a diameter of a pipe being produced.

By providing rolls of varying roll geometries, different support functions can be realized and varying support lines can be provided, for example a support of the pipe in the bottom area and various side areas. For example, one of the rolls may have a first roll geometry to conform to a maximum radius of a pipe being produced, and another one of the rolls may have a second geometry for lateral support of a smallest pipe to be produced.

Pipe extrusion lines are generally known. The production of plastic pipes involves initial melting of a plastic starting material in an extruder and discharge via a pipe die. The exiting thermoplastic molten tube from the pipe die is cooled under shape constraint and calibrated. Calibration is of great importance as far as pipe dimensions and tensions in the pipe wall are concerned. Plastic pipes are calibrated predominantly on the outside, whereby a vacuum calibration device is typically employed.

The still soft molten tube is drawn shortly after discharge from the die through a calibrator which is mounted in the vacuum tank. This calibrator can be configured as sleeve-type calibrator or disk-type calibrator depending on the thermoplastic material. The required contact pressure upon the calibrator is realized by the pressure differential between the normal pressure inside the pipe and the vacuum in the vacuum tank. The vacuum calibration device includes a vessel which can be sealed vacuum-tight and may be equipped preferably as cooling basin with spray nozzles. In and following the calibration path, the extruded pipes must be cooled down to such a degree as to be sufficiently stable in shape for subsequent loads (for example take-off device, winder). Cooling of the pipes may hereby be carried out in tanks with water baths or spray nozzles.

According to one aspect of the present invention, a roll assembly for guiding a pipe in a pipe extrusion line manufacturer for producing pipes of different diameter, includes a bracket, a roll supported by the bracket, and an adjustment device for automatically positioning the roll in vertical direction in dependence on a weight load upon the roll.

 

 

Summary of the pipe extrusion line

In one aspect of the present pipe extrusion line, the disadvantages of the prior art are overcome by providing a pipe extrusion die having a space separating the layer-forming channels. The structure of the pipe extrusion die with this space allows for pipes of more than two layers to be formed that may consist of different materials having different temperature profiles. Having a space between the layer-forming channels allows the added advantage that the individual die assemblies can be moved longitudinally prior to and during manufacture.

In another aspect of the present corrugated pipe extrusion line, there is also provided an extrusion die that allows for adjustment of the die lips from a location near the extrusion head. Adjustment of the die lips at a location near the extrusion head allows for adjustment of individual die layers and for die layers to be modified during manufacture of the pipe.

In a further aspect of the present corrugated pipe production line, there is provided an improved vacuum cooling mandrel that uses a single cooling channel with multiple vacuum ports to provide more control over the structure and appearance of the pipe that is formed.

According to one aspect of the plastic pelletizing line, therefore, there is provided an extrusion die for use in an apparatus to produce multi-layered pipes, the extrusion die comprising: (a) a first and second die assembly, each die assembly comprising: (i) an extrusion head having a central bore and a lateral opening for receiving an extrudate; (ii) a nozzle, operably connected to the extrusion head, the nozzle having an outer die lip at a free end of the nozzle; (iii) a hollow mandrel coaxially located in the central bore, (iv) an inner mandrel coaxially located in the hollow mandrel and in the nozzle, pipe extrusion line the inner mandrel having an inner die lip at a free end of the inner mandrel; the inner die lip and outer die lip defining a die gap; and, (v) the nozzle and inner mandrel defining a layer-forming channel in fluid communication with the lateral opening and the die gap; wherein a central portion of the nozzle of the second die assembly is co-axially located within the inner mandrel of the first die assembly such that the nozzle of the second die assembly and the inner mandrel of the first die assembly define an air space.

1. Guan molding: in principle, be greater than the total pipe extrusion line pressure to not flash basis

2. Pressure and speed are part of the relationship between the act on the same mold. In order to bring raw material into the mold to evenly and thoroughly, the full amount of each corner. Too low will be a short shot, shrink, too high a comatulid, fullness, viscosity mode, char, fragile mold and undesirable phenomena of higher internal stress

3. Speed: The speed of the decision of raw materials and finished products within the mold runner in the state, were going to flash, fullness, burning, slow short-shoot, shrink, combined with easily broken so bad

4. Temperature: different raw materials, the temperature varied, uneven color adhesive solution is too low, the internal stress of finished products increased. Supercharger too high due to low temperature, may lead to screw breakage, too high, products are flash, because of cooling produce temperature difference, causing contraction. materials will decompose, yellow, color, easy to break. cooling time becomes longer, exhaust gas is not easy, there will be gas gas.

5. Backpressure; screw feeding in the rotation when the back of the resistance called back pressure. Its role in the transportation of raw materials to more tightly compressed. Make raw air, water after the discharge from the screw. Made without affecting the sol finished surface of the gas composition. low there will be air bubbles, surface crazing. high overheat, agglomeration, excess glue, long period, screw refundable. while sucking back of the application is very important: back down, some materials to Song back, while others do not (according to the different nature of the raw material emphasized more than back pressure). backpressure is high and must be returned with a note from Otherwise pine air and non-intervention as the standard overflow glue.

6. The level of mold temperature and cooling duration influence the finished product viscosity model, shrinkage, dimensional tolerance, surface brightness, period, should be based on actual and timely adjustment of the international situation. Another acrylic, PC, such as when to have finished flesh mold temperature, it will not produce bubbles and stress.

Extrusion blow molding is a manufacturing method of hollow thermoplastic workpieces.  Widely blow system objects are bottles, buckets, cans, boxes and all packaged food, beverage, cosmetics, medicines and daily necessities of the container.  Big blow containers commonly used chemical products, lubricants, and packaging of bulk materials. There are other blow molding products, ball, bellows and toys. For the automobile industry, fuel tanks, car shock absorbers, seat backs, center armrest and headrest bracket and are blowing the cover. For machinery and furniture manufacturing, blow molding parts with shell, door frame, the system rack, jar, or to have an open side boxes.

Polymer
The most common pipe extrusion line high density polyethylene plastic raw materials, most of the milk usually made from such polymers. Often by other polyolefin blow to process. According to purpose, styrene polymers, polyvinyl chloride, polyester, polyurethane, polycarbonates and other thermoplastics can also be used to blow.
Engineering plastics in the automotive industry has recently been widely accepted. Material selection is based on the mechanical strength, weather resistance, electrical properties, optical properties and other performance-based.

Technology
1.   The 3 / 4 of the blow molding products are manufactured by the pipe extrusion machine .  Extrusion process is forced through a hole or a mold material to make products. Extrusion blow molding process composed of 5 steps: 1. Plastic-type embryo (hollow plastic pipe extrusion );
2.  The type embryos die close together will flap, and cut off the mold clamping type embryo;
3. To the mold cavity Inflation-based cold-wall training, adjusting the opening and to maintain some pressure during cooling, open the mold, the parts written by blowing; 5. repair flash get finished.

Extrusion
Defined as a polymer mixed with the polymer by melt mixing or polymer system to improve the level of a process. Mixing process from a single additive to deal with a variety of additives, polymer alloys and reactive mixed culture, its wide scope.  It is estimated that one-third of U.S. production to go through a mixture of polymer wear. Mix ingredients according to the performance requirements of the final application customization. Mixtures, mixed with hybrid performance, such as high gloss and good impact strength, or the precision molding and good stiffness.
Polymer mixture is often a good dice for further processing. However, a growing interest in industry is to combine the mixture with the next process, such as profile extrusion, so to avoid re-heating of polymer.

Mixing
People use various types of melt mixing equipment, roller mill and the batch from the mixer to the single screw and twin-screw extruder.  Continuous mixing to (pipe extrusion machine ) is the most commonly used equipment, because he can provide consistent quality products, and reduce operating costs. There are two types of hybrid: a mixture of materials distributed to remarry without ingredients in high shear stress can be evenly distributed. Extension of this type of mixture is called mixed or hybrid laminar flow.
Distributed hybrid also known as strong mixing, which impose high shear stress to break into a cohesive group of solid.  For example, when the additive material groups were broken, the actual particle size becomes smaller. Mixing operations are often required in a process of mixing two types.

Plastic extruders commonly convert granular resin feeds into sheets, films and shapes such as pipes. Normally plastic pipe is produced by extruding molten plastic through a pipe shaping die orifice of an extruder. As used herein a pipe shaping die orifice is an elongated annular opening formed between an internal mandrel and a surrounding bushing which is spaced apart from the internal mandrel.

Since the viscosity of the molten plastic is temperature dependent, temperature measurement is an important operational guide to extruder operation. Temperature control schemes generally divide the extruder barrel into temperature control zones, with a temperature control loop including a controller, temperature sensor, heater and an over temperature alarm for each zone. Band-type electrical resistance heaters of two piece construction to facilitate removal are generally employed for directly heating the barrel.

Extruders require large heater ratings to decrease heating time. After plastic extrusion lines have begun, however, heat is internally generated from friction, and at high production speeds the internal temperature, if uncontrolled, rises above the accepted maximum. Once the plastic has entered into metering section of the barrel, it is ready to be extruded into a die. The die is attached to the barrel and it represents the final shape or profile that the plastic is intended to take. The plastic is forced into the die. As the plastic moves forward into the die, it will be separated by a mandrel, which is centered in the extrusion channel.

Pressurized air is forced though the mandrel structure as a means of keeping the plastic from collapsing as it moves through the die. As the plastic leaves the die, it will enter into a vacuum environment. Inside the vacuum, there are sizing rings meant to keep the plastic in the desired shape. The vacuum environment also will be filled with water as a means of cooling the Plastic extrusion machine . After the extruded plastic has passed through the water-filled vacuum environment it can be cut or spooled as appropriate.

A pipe extrusion line for producing pipes with a variable diameter includes an extruder, an adjustable calibration device, and a cooling device, whereby a pipe to be produced is guided at least in part during the production process. In order to be able to provide a guide that is suited to different pipe diameters, a roll assembly is provided to include a row of rolls which are placed one behind the other in a take-off direction, with each roll mounted in a bracket and supported to allow vertical positioning thereof in dependence on the pipe diameter.

The plastic extrusion lines process starts with what are called thermoplastic resins. Thermoplastic resins are a type of plastic which can be melted, processed, and then re-melted to be used again. These resins are generally delivered in a pellet or bead form to be used in the plastic extrusion machinery .

The pellets or beads can come in several different forms. There are plastic resin beads, which come in what is referred to as a virgin form. These are beads which have never been processed before and generally come with certifications of purity. The beads are also available in grades of quality that can be purchased for specific uses. Waste plastic from the extrusion process can be reprocessed into beads that may be used again, which reduces the overall waste generated in the process.

Pipe Extrusion machinery can be complicated to operate, but the overall process is relatively straightforward. The heart of the machine is the screw, which sometimes is referred to as an auger. The screw is turned by a gearbox, which is powered by a motor. It is enclosed in a tight, heated barrel, which helps to provide friction.

The thermoplastic pellets are delivered into the machine through a hopper. The hopper is located at the rear of the barrel/screw assembly and the pellets drop into the barrel from there. As the screw turns, it slowly drags the thermoplastic pellets forward. The heat from the friction of the screw turning inside the barrel--along with external heating--melts the plastic as it moves forward in the barrel. The melted plastic is pushed into a section designed to meter the plastic for the next stage in the process. It also may be subjected to pressurized pumping at this phase of the process.

Plastic is increasingly replacing wood and metal for a variety of applications, is corroded where resistance against plastic conditions in rotting wood and metal particularly useful, for example in the field of design for the construction of doors and windows in the automobile industry to make vehicles components.Although these properties are attractive replacement for wood, plastic and metal, they create a problem for the effective elimination of waste plastic in the manufacture or scrapped when the product reaches the end of their useful life or damaged and must be replaced. In particular, most plastics can not be burned safely through the production of toxic gases a threat of contamination.

Consequently, the usual method of disposal of plastic waste in landfills is buried. The use of landfills is becoming more profitable as a means to get rid of waste and has attracted much negative publicity. In particular, landfills are increasingly difficult to develop because of problems of land subsidence and the emission of dangerous gases from the decomposition are waste.Accordingly, it is necessary for the efficient recycling of plastic waste, with no need for existing methods of waste disposal by landfill or incineration. Attempts to recycle plastic waste by plastic recycling machine have not been particularly successful to date. One reason for this is that plastic waste can often be prevented by substances that can be re-contaminated. Although the separation of plastic waste is possible, it is an operation time and work for a large portion of the profits. Consequently, only a small proportion (less than 10%) of plastic waste is currently in a form suitable for recycling are available.

 

The EPA (Environmental Protection Agency) has a national target, 25 percent of our national waste is recycled. Some plastics may be in recycling containers, food or recycled, lower recruitment centers. A high number (1-7) in a triangle on the bottom of most plastic containers for the type of plastic is and if they can be recycled.
to determine 1.Opening County Department of Public Works or recycling center to recycle what type of plastic and where to take it. Call for recycling 1-800-CLEANUP status information.
2.Rinse and sort your plastic containers by number. Recyclable plastic often must be separated by number in order to avoid contamination as it begins the recycling process.
3.Recycle type 1 (Pete) and Type 2 (HDPE) plastic containers in your sidewalk, according to local instructions. Type 1 and 2 containers include plastic bags, detergent bottles and milk, soda, juice, cooking oil and bottled water.
4.Drop plastic bags - mostly type 4 (LDPE), sometimes called type 2, but not always - in your supermarket for recycling by plastic recycling machine . Most large grocery chains have placed in storage containers. Types 2 and 4 can be mixed most of the time, but reading the first symptoms to be sure. Clean bags before recycling.
5.Call Alliance of Foam Packaging Recycling, (410) 451-8340 or visit the Web site to a recycling center in your area to find that foam packaging (type 6, Styrofoam or EPS to be carried out.) 6 Other items such as dishes made of plastic are more likely to be excluded.
6.Throw three types (plastic films and bottles of vegetable oil), yogurt cups (5, syrup bottles, diapers, a few bags, bottle tops and some food packaging) and 7 (laminate or mixed). Although some of them are recyclable, the plastics industry is still in its early stages of recovery and recycling of these in most cities, with the exception of a test program.

In plastic extrusion line apparatus including a rotating screw in a cylinder forming a channel receiving solid material and eventually expressing it through a die, the channel comprising a feed zone, a melting and compression zone and a melt pumping zone, the improvement wherein a solids decompression zone is between the feed and the melting and compression zones which has increased unit volume relative to that of the feed zone, with the channel of the melting and compression zone communicating with the feed inlet through the decompression and feed zones such that solids are initially metered producing a starved condition so as to melt at substantially atmospheric pressure without filling the channel of the melting and compression zone until close to its end.

The plastic extrusion process starts with what are called thermoplastic resins. Thermoplastic resins are a type of plastic which can be melted, processed, and then re-melted to be used again. These resins are generally delivered in a pellet or bead form to be used in the plastic extrusion machinery .

The pellets or beads can come in several different forms. There are plastic resin beads, which come in what is referred to as a virgin form. These are beads which have never been processed before and generally come with certifications of purity. The beads are also available in grades of quality that can be purchased for specific uses. Waste plastic from the extrusion process can be reprocessed into beads that may be used again, which reduces the overall waste generated in the process.

This invention relates to extrusion apparatus for melting solid plastic and generating hydrostatic pressure to force the melt through a die, and more particularly to an improved screw for use in such apparatus.

Continuously operating screw extruders for processing synthetic resinous plastic material are conventionally gravity fed from a source of stock in solid or particulate form to a screw portion beneath the feed inlet having the same or greater conveying capacity as that beyond the inlet. Systems under such conditions are said to operate in a flood feed mode, and traditionally exhibit a certain level of mass flow surging in the outlet die particularly at high throughput rates which results in corresponding undesirable fluctuations in extrudate weight. Such surging as manifested by fluctuating melt pressure in the delivery tube to the die is believed caused by a fluctuation in the axial position of the solid-melt interface along the screw. More specifically, when such interface moves rearwardly toward the feed end of the system, pressure and therefore mass flow through the die is increased whereas forward movement decreases pressure and mass flow. This fluctuation of the interface is a function of a number of variables such as, for example, extruder barrel temperature profile, head of material in the hopper feeding the extruder, temperature and bulk density of the feed stock, level of buildup of volatile products within the extruder and the like. Likewise characteristic of systems operating under flood feed conditions at high throughput rates are reduced power economy (mass extrustion rate divided by mechanical power) and increased occlusion of air which, if present, results in bubbles in the extrudate.

Plastic pipe extrusion line can be complicated to operate, but the overall process is relatively straightforward. The heart of the machine is the screw, which sometimes is referred to as an auger. The screw is turned by a gearbox, which is powered by a motor. It is enclosed in a tight, heated barrel, which helps to provide friction.

The thermoplastic pellets are delivered into the machine through a hopper. The hopper is located at the rear of the barrel/screw assembly and the pellets drop into the barrel from there. As the screw turns, it slowly drags the thermoplastic pellets forward. The heat from the friction of the screw turning inside the barrel--along with external heating--melts the plastic as it moves forward in the barrel. The melted plastic is pushed into a section designed to meter the plastic for the next stage in the process. It also may be subjected to pressurized pumping at this phase of the process.

Now, however, improvements have been developed in plastics extrusion apparatus which reduce or substantially overcome the aforementioned prior art shortcomings.

Accordingly, it is a principal object of this invention to provide an improved screw member of novel construction for use in extrusion apparatus which is capable of self-regulating a feed of particulate material from the extruder inlet to the downstream zone of the extruder.

Another object is to provide such a screw member which permits operation of the extruder hopper in the flood feed mode while achieving the metered-starved state with respect to the screw without the use of apparatus external to the extruder.

Another object is to provide a self-starving screw member for use in a plastics extruder which substantially reduces torque and mechanical power requirements, improves volatiles venting and provides a high degree of uniformity of mass flow and pressure at the die.

Other objects of this invention will in part be obvious and will in part appear from the following description and claims.

These and other objects are accomplished in plastic extrusion line apparatus which includes a hollow cylinder having an inlet for containing a bed of solid plastic, a rotatable screw within the cylinder defining with the cylinder a helical channel for the plastic comprising in series, a feed zone beneath the inlet and a melting zone, by providing the improvement which comprises a solids decompression zone between the feed zone and the melting zone having increased free volume relative to the feed zone whereby before significant melting occurs the bed of solid plastic is decompressed to the extent that the channel in the solids decompression zone is partially filled. Once the plastic has entered into metering section of the barrel, it is ready to be extruded into a die. The die is attached to the barrel and it represents the final shape or profile that the plastic is intended to take. The plastic is forced into the die. As the plastic moves forward into the die, it will be separated by a mandrel, which is centered in the extrusion channel.

Pressurized air is forced though the mandrel structure as a means of keeping the plastic from collapsing as it moves through the die. As the plastic leaves the die, it will enter into a vacuum environment. Inside the vacuum, there are sizing rings meant to keep the plastic in the desired shape. The vacuum environment also will be filled with water as a means of cooling the extruded plastic. After the extruded plastic has passed through the water-filled vacuum environment it can be cut or spooled as appropriate.

ABS known as acrylonitrile butadiene styrene is determined by acrylonitrile - butadiene - styrene three kinds of monomers formed. As the ratio of three different monomers may have different properties and melting temperature, flow properties of ABS plastic or additives, such as blending with other even more can be extended to different uses and performance of ABS, such as resistance to impact grade, heat-resistant grade , flame retardant grade, transparent level, enhance the grade, electroplating grade and so on.

ABS between mobility between the PS and the PC, its mobility and the injection temperature and pressure have a relationship, in which the impact of injection pressure is slightly larger, so forming a higher injection pressure is often used to reduce the melt viscosity and improve charge mode performance.

1, plastic recycling machinery processing
  ABS water absorption of about 0.2% -0.8%, for the general level of ABS, with the processing of pre-bake oven 2-4 hours to 80-85 ? or 80 ? drying hopper to bake 1-2 hours. PC-containing components of the heat-resistant grade ABS, proper drying temperature raised to 100 ?, a specific drying time can be used to determine the air squeezed out.

The proportion of recycled materials used does not exceed 30%, plating grade ABS can not use recycled materials.

2, injection molding machine selection

Ramada can choose the standard injection molding machine (screw 20:1 aspect ratio, compression ratio is greater than 2, injection pressure is greater than 1500bar). If the use of master batch material with high demand or product appearance may make use of the small diameter of a screw. 4700-6200t/m2 to determine the clamping force according to the specific grade and products must be in accordance plastic recycling machine request.

3, mold and gate design

Mold temperature can be set to 60-65 ?. Flow channel diameter 6-8mm. Gate width of 3mm, thickness and products, as the gate length is less than 1mm. Vent width 4-6mm, thickness 0.025-0.05mm.

4, melt glue temperature

Air injection can be accurately determined. A different level of adhesive melting temperature is also different, it is recommended to set as follows:

Anti-impact grade: 220 ? -260 ?, in order to better 250 ?

Electroplating Grade: 250 ? -275 ?, in order to better 270 ?

Heat Level: 240 ? -280 ?, in order to better 265 ? -270 ?

Flame Retardant: 200 ? -240 ?, in order to better 220 ? -230 ?

Transparency Level: 230 ? -260 ?, in order to 245 ? is better.
Glass fiber reinforced grade: 230 ? -270 ?

High requirements for surface products, use of the higher melting temperature and mold temperature glue.

5, injection speed

Fire-rated to use a slow, heat-resistant grade with quick. Such as the product surface are higher, and it will need high-speed and multi-stage injection Blow Moulding Machine of the rate of fire control.

6, back pressure

    Under normal circumstances back pressure as low as possible, a common back pressure is 5bar, coloring need to use a higher back pressure in order to blend evenly.

7, retention time
  At 265 ? in temperature, ABS plastic barrel in the melt residence time of a maximum of 5-6 minutes. Flame-retardant shorter, and if shut down, we should, first set the temperature as low as 100 ?, then general purpose grade ABS plastic tube cleaning melt. Clean-up after the mixture should be placed in cold water to prevent further decomposition.For reform to play from other ABS plastic material, then the first with the PS, PMMA or PE melt glue tube cleaning. \Some of ABS products in just stripping no problem when, over a period of time before there will be discoloration, which may be overheating or plastic in the molten plastic recycling machinery tube to stay too long due.

8, products, post-processing
 ABS products generally do not need post-processing, only the plating grade products subject to baking (70-80 ? ,2-4 hours) in order to trace the surface passivation, and the need to electroplating products can not use the release agent, product packaging immediately after taking out .

9, forming special attention when

There are several grades of ABS (in particular, flame retardant grade), after the melt in the plasticizing screw surface adhesion of the great break after a long time. When the above situation, we need to segment and compression screw were pulled out of smear, and on a regular basis with the PS and other clean-up screw.

This invention concerns improvements in and relates to plastic recycling machinery , in particular to recyclable hangers made from plastics materials.

A wide variety of hanger shapes and sizes are currently available, the hangers being made from a variety of materials, with however the majority of hangers being formed from polystyrene (PS). Garment hangers are used in the clothing trade as a method of transporting garments from a factory to a retail outlet and as a method of displaying the garments within the retail outlets. Very often hangers are also used to display various features of the garment, such as size and/or cost to the prospective consumer. In addition, hangers can also be used to display the numeric code or bar code of the garment. This enables a retailer to quickly access the numeric code or bar code rather than spending time locating the garment label attached to the inside of the garment when dealing with queries in respect of said garment. Generally this information is displayed on a label which is then attached to the hanger, by adhesive means.

The EPA (Environmental Protection Agency) has set a national goal to recycle 25 percent of our national waste. Some plastics can be recycled through plastic recycling machine , grocery store drop bins or drop-off centers. A raised number (1 through 7) in a triangle on the bottom of most plastic containers tells you what type of plastic it is and if it can be recycled.Call your county's Department of Public Works or recycling center to determine what type of plastic to recycle and where to take it. Also call 1-800-CLEANUP for state recycling information.

Accordingly, the present invention provides a recyclable plastics materials including a polystyrene compatible label, where the polystyrene compatible label is attachable to an object using a polystyrene compatible adhesive.

Advantageously, the object to which the label is attached is formed from polystyrene or a polystyrene compatible material.Rinse and sort your plastic containers by number. Recyclable plastic often must be separated by number in order to avoid contamination as it begins the recycling process.Recycle type 1 (PETE) and type 2 (HDPE) plastic containers at your curb, according to local instructions.

Systems and methods of generating a recycled output are disclosed. This recycled output may include a fabric produced by fusing reclaimed plastic bags. The reclaimed plastic bags are fused together using a material manufacturing system. This system is typically configured to heat the plastic bags to a temperature wherein the plastic bags fuse together but do completely melt. Some embodiments include the addition of different types of plastic or non-plastic materials to the recycled output. Also disclosed are systems and methods of controlling textures and patterns within the recycled output.

Starting your own plastic recycling machinery is a serious undertaking. It demands a lot of research and typically requires a sizable startup investment. The business actually is much more involved than simply collecting scrap plastic and selling it to a consolidator for processing. Opening a recycling business means handling the plastic from start to finish. Despite the challenges, here are some tips for those who are determined to get into this potentially lucrative and ecologically "green" business.

 Plastic includes a variety of synthetic and semi-synthetic materials. They are typically composed of organic polymers and may contain other substances to achieve desired characteristics. There are also some natural polymers generally considered to be “ plastics.” Examples of plastics include High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene (PP), Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), and Polystyrene (PS).

Plastics may be sorted according to their resin identification codes and recycled. Recycling methods include taking scrap or waste plastics, reprocessing them and turning them into useful products. One relevant reprocessing method that can be applied to a large family of plastic material is called heat compression. In this method, the plastic material is liquefied while spinning in a large drum. The resulting liquefied plastic is then pumped into casting molds and re-made into a new useful material. This process, however, is not energy efficient. PET recycling line in general can be expensive due to the costs associated with running the heat compression machinery and the work required to sort and reprocessing various plastic materials. The presence of additives, dyes and fillers in plastic can also complicate the recycling of plastics. For these reasons and others, there is a need for improved systems and methods of plastic recycling.

Determine who will be supplying the scrap plastic you will be recycling. Ask possible sources what type of plastic they supply: thermoplastic or thermoset. You'll probably want only thermoplastic, because it can be melted and remolded; thermoset plastic cannot. There are many variations of thermoplastic, but you should deal only with one kind to avoid incompatibility. Also ask providers about the thickness of the plastic, how much they can provide, whether the scrap will be wet or dry, and the type of contaminants that can be be expected with their materials. Get firm pricing information and do not sign a contract until you have procured a business location and machinery.

Various embodiments of the invention include recycling plastic into useful materials through a process of heat fusion. The plastic is heated so as to fuse with adjacent plastic or other material. The plastic may include LDPE, HDPE, other plastics discussed herein, and/or the like. For example, in some embodiments, the plastic includes LDPE plastic bags such as those commonly used as shopping or trash bags.

The plastic is processed at a temperature at which it can flow to create mechanical bonds with other plastic and/or non- plastic material. The plastic need not be heated to a temperature sufficient to liquefy all of the plastic. For example, in some embodiments, part, e.g., the surface, but not all of a plastic is liquefied during the fusing process. In other embodiments, the plastic is maintained below a temperature required to liquefy the plastic. The plastic may be fused with plastic of the same type, plastic of a different type, and/or non- plastic materials.

The plastic may be processed using rollers, a press or a mold. For example, in some embodiments, plastic bags are guided between a set of rollers. These rollers are configured to cause layers of the plastic bags to fuse with each other by heating and/or compressing the bags. The result of fusing the plastic bags can be a recycled fabric. In another example, plastic bags are pressed within a mold in order to form a three dimensional device.

Base the location on how much area you will need for the scale of your business. Try to find a locale that is relatively remote so residents and community businesses will not be bothered by the noise and dirt associated with recycling. Make sure the area is properly zoned for a Plastic recycling Machine business. The ideal location will have access to a water treatment system to handle the dirt removed from plastic scrap, and a paved roadway for delivery trucks.

Various embodiments of the invention include controlling a surface finish of a recycling output. For example, in some embodiments, one or more temperatures of the plastic are manipulated to generate a desired surface texture. In some embodiments, a desired surface texture of the recycling output is generated by having a surface texturing material in contact with the plastic during or following the fusing process. In some embodiments, this surface texturing material is part of a roller, press or mold. In some embodiments, this surface texturing material is placed between the plastic and a roller, press or mold.

Consider the type of machinery you will need: a sorter that can handle the type of scrap you will have (wet or dry), a shredder and granulator, washing machines, and a centrifuge for drying. You will need to devise how the recycling process will flow. Meet with several pet bottle recycling Machine suppliers to fine-tune your plans and to compare equipment prices.Obtain financing for your recycling business. If you don't have enough in startup funds, apply for a small business loan or consider looking for an investor.

A plastic extrusion line apparatus of the type employing a rotatable screw mounted in an elongated tubular member and including pressures fluid operated piston means operably connected to the screw for applying a compressive axial force to the screw in a direction toward the discharge port of the extrusion apparatus. The apparatus further includes means operably connected to the piston means for ejecting the screw from the tubular member upon reciprocation of the piston means.

This invention relates to a plastic extrusion apparatus; more particularly to an extruder which employs hydraulics to produce unique advantages in the normal extrusion operation and in the servicing procedures associated therewith.

Plastic pipe extrusion line of thermoplastics consists of the melting and compressing of plastic particles while they are being forced through a long passage by a screw conveyor turning in that passage. The opening at the end of the passage takes various shaped depending on the desired cross-section of the finished product.

A typical extruder includes an elongated screw mounted for rotation within a barrel. The end of the screw nearest the feed opening is engaged with a drive sleeve. The drive sleeve, in turn, is mounted in a thrust bearing which is intended to absorb the large axial loads generated by plastic being forced through a discharge opening (or die) at the opposite end of the barrel. Tapered roller bearings are commonly used as the thrust bearing. A recurring problem which arises in extruder operations is the uneven application of force to these roller bearings caused by mis-alignment of the screw and/or the barrel with corresponding reduction in bearing life.

The power source for rotation of the screw is generally an electric motor operating at varying speeds within its normal range to provide the necessary horsepower for the particular extrusion operation. In practically all cases, an electric motor requires large speed reduction equipment in the drive system to produce the torque needed in plastic extrusion lines . For example, 15:1 drive reduction ratios or greater are common in electrically powered extruders. The large drive reduction components required in these extruders create over-all machine design problems and often complicate the alignment of the entire assembly.

Since a single plastic extruder for a plastics manufacturing line costs tens of thousands of dollars or more, it is essential to find the root cause of excessive wear as soon as possible to avoid damaging this expensive equipment. Here are some simple steps to do just that.

Measure the surface distance of the screw from the shaft. If the screw is bent, then it will cause plastic to flow at excessive pressure in a direction the equipment is not designed to have, wearing the screw barrel with the fluid flow of molten plastic. Imagine a river carving a canyon, but this is very hot molten plastic wearing out metal.


In any extruding machine, it is necessary that the screw and the inside of the barrel be cleaned periodically. This is always true when the feed material is changed so that co-mingling of different plastic materials is avoided. The cleaning operation necessitates removal of the screw from the barrel which can be a laborious and time consuming procedure. Most often screw removal is accomplished by a mechanical pusher attached to the drive end of the screw. The pushing apparatus may take the form of a threaded rod as in U.S. Pat. No. 2,090,434 or the form of a hydraulic ram as in U.S. Pat. No. 3,015,844. In any case, screw ejection mechanisms known heretofore are considered accessory equipment and are not integrally operable with the extruder components.

I have discovered an extruder which includes hydraulic drive means and a hydraulic thrust bearing in a configuration which enables me to achieve significant design efficiencies not present in known extruders.

I provide a plastic extrusion line manufacturer apparatus comprising a housing; a rotatable drive member having an axial bore supported for rotation within the housing; hydraulic driving means coupled with the drive member for rotating the drive member; an elongated tubular member connected to the housing and extending therefrom in co-axial alignment with the bore of the drive member, the tubular member having a discharge port in the end remote from the housing and a feed opening adjacent the housing; a rotatable screw slidably mounted within the tubular member and releasably connected to the drive member, the screw being capable of axial motion relative to the drive member but being engaged with the drive member for rotation thereby; pressure fluid operated first piston means operably connected to the screw for applying a compressive axial force to the screw in a direction toward the discharge port; and means operably connected to the first piston means for ejecting the screw from the tubular member upon reciprocation of the first piston means.

Measure the barrel for straightness. It it was dropped during installation, dropped, rotated and warped by a motor or otherwise bent, the extruder screw itself may be wearing against the plastic extruder barrel.
Check the alignment of the extruder shaft and the gear reducer. If the extruder screw is at even a slight angle in any part of the barrel rotation, the barrel gets excessive wear. This will occur whether the screw comes into contact with the barrel or the more narrow gap than designed during plastic extrusion line causes extra pressure on the molten plastic to deform the extruder barrel.

At Drinktec, Sidel is launching the SBO Universal(TM)2 range, which accelerates industrial blow molder outputs by 10% – reaching 2,000 bottles per hour per mold – while also decreasing energy consumption by 10% in the ovens. The result is the possibility of blowing bottles from pet bottle recycling Machine .

With this new record speed of 2,000 bottles per hour per mold, Sidel is widening its portfolio of solutions for the still and sparkling beverage markets. This output rate is the result of a long, rigorous qualification process that has already been
tested and validated during industrial production at several customer facilities.
This speed, which is ideal, reliable and safe for intensive industrial operation, applies to all machines in the SBO Universal(TM)2 range, up to SBO 24 XS. Also available in Combi configuration, the SBO Universal(TM)2 range reaches record productivity levels as well, without any compromise in terms of robustness or production reliability. Unplanned machine downtime is reduced to less than 3% due to the use of more robust components and a fewer number of spare parts. It also ensures flawless productivity with guaranteed yields of 97% and optimized production costs.

In addition, the new SBO Universal(TM)2 machines benefit from the same heating reserve that is already available with SBO Universal(TM) equipment. The oven configuration with 50 mm pitch (distance between two spindles) ensures a sufficient heating time for an output rate of 2,000 bottles per hour per mold. New lamps and oven adaptations enable a decrease in energy consumption of up to 10%.

Reaching this new performance level for blow molding represents a new step forward in reducing the environmental impact of each PET bottle during its production.

Generalizing the use of plastic recycling machine

At the same time, Sidel is also committed to improving the environmental footprint of the bottle itself, by facilitating the generalization of bottles made from recycled PET resin. The 1.5-liter mineral water bottle produced at the Sidel stand with an SBO 14 -at a speed of 2,000 b/h/m- has all the attributes of a traditional PET bottle – crystallinity, resistance and elegance. However, it can display plantbased forms on its sides since it contains 50% recycled materials. This bottle is the fruit of a joint development with Husky, the world leader in PET preform injection systems.

Since the use of recycled materials is one of Sidel’s focus areas for reducing the industry’s environmental footprint, the Group is working hand in hand with the plastic recycling machinery and with bottlers in order to pursue a single objective: to give more weight to the production of recycled PET bottles. And a single commitment: to ensure reliable production for this type of package, by obtaining equivalent industrial performance to that with virgin PET bottles. For several years now, Sidel has been conducting a number of tests to qualify resins and to adapt its equipment. Still, 50% recycled material is not the limit. Sidel is continuing its work and has already conducted laboratory tests on blowing bottles with 100% recycled materials, ready for market. This can be done without affecting blowing performance because of the wide processability window for these machines.

These innovations, along with continued work on package lightweighting, bear witness to Sidel’s firm commitment: being the leader for plastic packaging equipment means having the opportunity, the power and the responsibility to change the plastic bottling universe.

About the Sidel Group

With more than 30,000 machines installed in 190 countries and with annual sales of 1.19 billion euros in 2008, the Sidel Group is one of the world’s leaders in beverage packaging solutions: water, carbonated soft drinks, milk, sensitive beverages, oils, beer and alcoholic beverages.

2010 Machinery Industry sales growth is expected to reach 15%, profit growth is expected to reach 10%, and export growth is expected to reach 15%. In the China Machinery Industry Federation recently held three secondary members of Congress, executive vice president of the machine in conjunction of the 2010 machine-building industry has made major economic indicators for the latest forecasts.

In 2009, China’s plastic recycling machinery industry rose 13.8% value-added, total output growth rate reached 16.07%, machinery industry maintained a stable and rapid growth. However, structural adjustment, with the major equipment compared to the results of independent innovation, “Laying a Solid Foundation,” the progress has lagged far behind; and the rapid rebound in the domestic market compared to the monthly value of exports have not yet effective amplification; compared with the current economic growth, trade long-term sustainability is still optimistic about the prospects for steady growth. As a result, predicted to run China’s machinery industry in 2010 will show the trend from high to low.

Structural Adjustment bear fruit fruitful independent innovation

From 2009 the operational features of China’s plastic recycling machinery industry point of view, equipment manufacturing and automotive industries to restructure and revitalize the implementation of effective planning policies to gradually release the effects of policies to support key industries, particularly notable, agricultural machinery and automobile industry policy support under the pick-up is noticeably faster than in other industry, particularly in the automotive industry, machinery industry growth in 2009 to become the “engine.” The automobile production and sales in China has leapt to the superpower.

While maintaining steady and rapid development at the same time, mechanical bear fruit showing signs of adjustment of industrial structure.

Second half of 2008 to May 2009, China’s pet bottle washing line machinery industry output value of new products, industrial output growth rate has been lower than the same period. Since June 2009, the new products, higher growth rate from month to month throughout the year value of new products increased by 23.74 percent, industrial output growth rate has been higher than the same period, which showing that the industry and technological progress driven by the demand in the market to become more active again.

From basic machinery industry perspective, the various industries in decline at the same time, structural optimization presents highlights: According to the 197 key enterprises of the machine tool industry statistics, in 2009 1 September NC metal processing machine tool production rate increased by 6 percentage points year on year, reaching 53.6%; metal cutting machine tool production fell 30.6%, but the average unit price increased by 34%; cnc plasma cutter machine tool production fell 13.8%, unit prices increased by 21%. Moreover, the decline in production of CNC machine tools significantly less than general machine tools, CNC machine tools in the production of high-end machine tools fell significantly less than the economic-type machine tools, machine tools this can be seen clearly escalating momentum.

At the same time, and energy-saving emission reduction-oriented product structure adjustment has also made great progress. 1.6 liter and below low-emission passenger car sales of 7.1955 million annual aggregate, up 71%, accounting for 70% of the total passenger car sales over the previous year by nearly 8 percent of the entire automotive market degree of contribution to the increase reaching 70%; wind power generation equipment and DC power transmission equipment, and other new energy sources and equipment to double production growth, medium and large horsepower tractors and other agricultural equipment, and efficient growing rapidly; efforts to contribute to energy reduction has become an industry-wide consensus on this as a important orientation of product structure adjustment is more and more enterprises attach great importance.

Cope with the international financial crisis, the plastic extrusion line machinery industry enterprises have increased their R & D investment, more emphasis on endogenous levels of development improved.

Among them, the world’s leading standard of living in the exchange of complete sets of equipment in the UHV line safe operation of pilot demonstration has been a year, special high-voltage direct current key equipment was put into operation by the end of 2009 a successful, 30 kilowatts or more large-scale thermal power production accounts for thermal power production rose from 2008’s 80.8% to 82%; independently developed a large-scale open pit mine 220 tons of used electric-wheel dump truck was completed in 2009 identified; million tons of ethylene installation of the required three main compressors and multi-stream low-temperature cold box The successful development of domestic natural gas pipeline compressor and the valve was finally implemented in the West-East Gas Project Phase II development contract; 1080 tons and 500 tons of crawler cranes, all terrain cranes, etc. The successful development of large construction machinery; high-end CNC machine tools and basic the implementation of major national special pet bottle washing line manufacturing equipment to make progress, the highest in the world’s largest listed size of the boring bar diameter of 320 mm, floor boring and milling machine was successfully developed; 36,000 tons of ferrous metals vertical extrusion machine developed. Uneven products sales phenomena are no longer together all sectors showed growth potential.

Analysis of the current domestic and international situation and the development of the industry status, said that the total demand by 2010, although the machinery industry rose steadily, but because of industry-wide capacity to grow too fast, it will become more intense competition, businesses are feeling the competition pressures will continue to increase; the whole industry sales volume will continue to build on the steady growth over the previous year, but under the impact of excessive competition and efficiency growth rate may be lower than the production and marketing; in 2010 will be the beginning of the growth rate is relatively high, even higher than the 50%, but then will gradually decline, annual growth rate curve will show a clear trend from high to low.

Based on the above analysis, which is sub-development of the industry made a prediction. Among them, agricultural machinery industry: the demand for farm machinery purchase continuing positive impact of national policy is expected to remain at the next higher level than the previous year but the growth rate slowed down and sales are expected to grow by 10% ~ 15%.

Construction plastic pipe extrusion line Machinery : growth rate of the high and then low, about 10% of the whole year is expected to achieve moderate growth, the various main products is expected to reduce the gap between the products sales.

Electrical industry: domestic demand continued to decline conventional power generation equipment, but still essential to maintain the original orders for the normal production this year is expected next year after a serious shortage of mission will usher in a severe test; in the future the proportion of exports in total output will increase; power station cast contradiction is expected to slow down the supply of forgings; wind power and nuclear power and new energy equipment and mining is expected to increase in demand for electrical equipment; transmission and distribution equipment due to excessive capacity expansion and network growth rate of investment is limited, so competition is expected in 2010 will significantly increase. The whole industry is expected to grow by about 12%.

Heavy Mining Machinery: metal rolling equipment, metallurgical equipment, and demand continues to sluggish demand for mining equipment, mining and pet bottle washing line is expected to remain stable, large castings and forgings as a breakthrough in thermal processing technology and key equipment, significant improvement in production capacity is expanding rapidly, imports replacement volume will be increased significantly. Industry-wide sales are expected to grow by 5% ~ 10%.

General petrochemical equipment: machine valve and tower cauldron and other petrochemical and general equipment demand is expected to maintain steady growth, particularly in nuclear power, natural gas, liquefied natural gas, long-distance pipelines and installations needed for high-end products will be a breakthrough in independent innovation has a broad prospects for development. Industry-wide sales expected to grow by about 15%.

Machine tool industry: In the large aircraft and nuclear power and other major scientific and technological support of special needs, the high-end CNC machine tools and heavy machine tools, production situation will remain in good condition, all kinds of special plane to meet user requirements and the line has broad space for development, heavy-duty machine tools new orders growth is expected to be slowing down, there is no basis for the proposed business should not blindly enter.

plastic recycling machine industry: purchase of 1.6 liters and below, preferential policies intensity of low-emission vehicles by half, but to encourage trade-in policy efforts to increase; China’s auto market there is still much room for development, the automotive market is the second-line and extended the following cities and rural areas, aggregate demand will continue to grow, but the momentum of growth will significantly slow down this year, is expected to grow about 10%.

Instruments: energy-saving environmental monitoring and control equipment, the people’s livelihood with the instrumentation, process monitoring and control equipment for industrial use in high-grade, factory automation and control equipment using relatively quickly, the whole industry is expected to grow around 11%.
