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 anti-corrosion 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.
Designed by modular principle.
Precise processed, agile combination
Self-cleaning,transmission,compounding
Screw element:
