Screw Element And Segment Screw Barrel From China Screw Factory
1. Descriptions
Screw elements: Designed by modular principle. Precise processed, agile combination Self-cleaning,transmission,compounding.
Twin screw extruder screw element:
· convenient interchangeability by agile combination.
· fulfill efficient self-cleaning, transmission, compounding, pressure-forming, etc.
· made of high tool speed W6Mo5Cr4V2, or anticorrosion steel 38CrMoAlA by special treatment.
Assembled together, they will become twin screw which are essential and key part of extruders for material to transmission, shearing and plasticization.
