Have you ever wondered how composite windows, vinyl fencing or freezer gaskets are made? These and many other products are produced using a high-volume manufacturing process called plastic extrusion.
Extruders are the equipment at the heart of this manufacturing technology. Whether it's a hundred pipes or a thousand straws, plastic extrusion is used frequently in today's plastics industry because it is easy to obtain and easy to use. The plastic extrusion process involves melting plastic material, pressing it into a die to form it into a continuous profile, and then cutting it to length. The process is a good choice for applications that require a final product with a constant cross-section. The low cost and high productivity make it a popular manufacturing choice for products such as pipe, plastic sheeting, weather stripping, wire insulation and tape - to name just a few common plastic extrusions.

Twin Screw Lab Extruder
Suitable for universities and scientific research laboratories used for technology, formula development, small-scale production.
For Masterbatch (MB) Production Line, we provide high quality Twin-Screw Extruder and complete masterbatch making lines. JIEYA provides the advanced extruders for all kinds of masterbatch, such as PE, PP, EVA, ABS, PC, PS, etc with high percentage of calcium carbonate, talc, Tio2, Sio2, Baso4, etc compounding. We can offer you the best solution based on your formula，output and application request. We have competitive advantage in this market.
Biodegradable plastic, or bioplastics, are derived from renewable raw materials like plant starch, cellulose, soy protein, and lactic acid and are biodegradable because microorganisms consume them as a food source. To protect the environment.
TPU line is a kind of thermoplastic elastomer material. The main raw materials for production are polyether or polyester, which is prepared by copolymerization with diisocyanate, and the product has good comprehensive performance. Due to its unique properties, TPU has a wide range of applications. It can be used as raw materials for cold-resistant cables and heat-resistant wires in wire and cable industry, as well as engineering plastics such as rollers, gears and various seals in industrial manufacturing.
Two-stage extruder is the core equipment for producing PVC cable materials, and taking advantage of the twin-screw extruder and a single screw extruder. The twin-screw extruder realizes transportation, high effective plasticizing and compounding, dispersion. The two-stage machine can also increase the variable operation and realize the process. It has higher effective and production capacity, and is good at processing heat-sensitive materials and devolatilization operations. Our company has over 20 years of experience in provinding two-stage (twin screw+single screw) extruders for rigid/soft PVC cable compounding.
In air cooling strand pelletizing, polymer strands exit from the die head and the strands are cooled by conveyor belt and automatically conveyed to the strand pelletizer. The cooling is done by special air fans with high cooling capacity.
Air cooling strand pelletizing line can be used to processing and application of partial high polymer material, including PVC, LLDPE, mastebatch, hihg filling caco3 masterbatch, degradable masterbatch, high density carbon masterbatch, and so on.
Underwater Pelletizing
Underwater pelletizing system is good for most of polymers. Especially for TPU and TPV or similar elastomer, its advantage plays well.
It consists of drive valve, die head, pelletizing unit, bypass line, water recycling unit and centrifugal dehydrator.
It is widely used for elastomer plastics, modified plastics, hot melt adhesive, micro plastics, biobased plastics, medical plastics, recycled plastics, etc with the advantage of wide applications and high efficiency.
Water Ring Die Face Pelletizing
For water ring die face pelletizing , molten polymer flows into multiple holes arranged in a circular pattern in a die plate and is cut into pellets as it emerges from the die face. The cutting is accomplished by a series of rotating knives that are also arranged in a circular pattern. After that, it goes into the centrifugal dewatering for water removal.
It is suitable for filler masterbatch, cabon black masterbatch, grafting compounding, etc.
Our Customers
Since 2004, now we have 20,000 square meters workshop with annual sales over 300+ sets, export over 60 countries.
FAQ
What’s the differences between twin screw and single screw extruders?
The mainly differences is that single screw extruder is suitable for single material extrusion, for example, single granule, flakes, film, etc while twin screw extruder is suitable used for compounding.
What’s the different cutting systems of plastic extruders?
It includes strand cutting, water ring die face cutting, air cooling hot face cutting and underwater cutting. Different formula is with different cutting system.
What kind of plastic extruders Jieya supply?
We’re specialized in manufacturing twin screw compounding extruders, single screw extruders and two stage extruders with over 20 years experience.
What’s the differences between standard and high torque plastic extruders?
It includes main motor power kw differences, coupler differences, torque grade of gear box differences, shaft material differences and output differences. If customers require high torque, high output and high performance plastic extruder, we recommend high torque type.
How to select plastic extruder?
We will offer the best suitable solution after getting customers’basic formula and specific requirement. All of our plastic extruders are custom-built to meet more and more customer’s needs with output from small-scale production to large-scale production.
What is plastic extruder?
Plastic extruders include twin screw extruders, single screw extruders and multi-screw exruders. It can be matched with various kinds of downstream lines to make granules, pipes, films, sheet, straps, etc.
Nanjing jieya manufactures two stage compounding system for PVC and thermosensitive plastics.
The first stage is a high-speed co-rotating twin-screw compounder.The second stage is a low-speed single-screw extruder.
The two are arranged vertically and orthogonally to form a double-stage extruder,combining the advantages of co-rotating twin-screw and single-screw to complement each other.
Suitable for universities and scientific research laboratories used for technology, formula development, etc. It is with beautiful appearance, compact structure, easy to use and maintain, precise process conditions control and other characteristics.
Laboratory twin screw extruder possesses the successful genes of the NJJY(Nanjing Jieya) technology. It was developed especially for processing of smallest batch sizes. The reliable scale-up to larger twin screw extruders make it the ideal compounding system for formulation development and basic scientific research.
Ideal for universities and scientific research facilities engaged in technological advancements, formula experiment and small scale materbatch production.
Small- and medium-sized underwater pelletizers are used primarily in compounding and in the production of engineering thermoplastics. Their throughput ranges from just a few kg/hr up to approximately 20 tons/hr.
Single screw extruders is suitable for extrusion granulation of softening plastic,gentle blending and recycled plastic. It also can be combined with a twin screw compounding extruder applied in pvc cable compounding, recycled plastic regraulating ,etc.
