Specifications of this conical twin-screw and barrel:

  Φ45/90 Φ45/100 Φ50/105 Φ51/105 Φ55/110 Φ60/125 Φ65/120 Φ65/132 Φ80/143Φ80/156 92/188

The screw compression ratio should be decided based on different ingredients and different products.

Technical indexes:

38CrMoALA, Nitriding process, Surface hardness:HV>900,Nitriding layer depth:0.5-0.8mm, Chromium plated hardness:>1000HV, Chromium layer thickness:0.01-0.10mm, twin-alloy hardness:HRC60~70, twin-alloy depth:>2mm, Screw edges are made by twin-alloy which could improve screw's using life.The feeding place where is easy to abrade is made by alloy which could improve the abrasion effectively.

Applicable scope:

common plastic,PP, PE, ABS, PVC, pelleting,pipe,special-shaped,plate,sheet,wood-plastic.
