  • 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.
