Onyx Co-Rotation Twin Screw Extruder Compounding and Sheet Line

The system is designed for compounding bio-composite and bio-material. The complete compounding line is consisted of :

  1. one 65 mm Co-Rotation Parallel Twin-Screw Extruder for compounding polymer and additives or fillers;
  2. one die face cutting pelletizing line to transfer the melt into pellet;
  3. one 120 mm single extruder to convey the melt from up twin-screw extruder into the sheet or profile die to make end products;
  4. one 3-roller calender sheet line to make 20 inch wider polymer composite sheet with wide range of thickness.

Both the screw and barrel of the twin-screw extruders were designed using the building block principle. The screw configuration, barrel setup, screw L/D, number of feeding & venting protocols, screen changes, granulating methods and electrical controls are optimally adjusted according to the material properties and process requirements. The closely intermeshed screw elements have excellent self-wiping characteristics, and can be easily interchanged with others.
