What Is Plastic Extruder
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.

Basic Screw Extrusion Process
Plastics extrusion is a high-volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weather stripping, fence, deck railing, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation. This process starts by feeding plastic material (pellets, granules, flakes or powders) from a storage hopper into the barrel of the extruder. The material is gradually melted. As the melt proceeds down the barrel of the extruder towards the die, it is forced through the die opening to form a shape. The extrudate is cooled in an air or water bath so that it hardens and can be pulled onto take-up rolls for storage.

Twin Screw Extruder Barrel Configuration:Close Barrel

Closed Barrel SectionsThe most common barrel section design is, of course, the closed barrel section (Fig. 2). This barrel section fully encases the polymer melt on all four sides of the extruder with only a figure 8 opening through the center for the screws.

  • 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?

    Were 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 customers 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.
