Scope of application: pipe, film, profile, sheet, pvc pe/pew pc pelleting etc.

For good plasticizing effect, we have different design of screw & barrel to meet your requirements

Screw Type:

Gradient-type, mutant, wave type, barrier type, dual type, shunt type, separate type, exhaust type, pin type, mixed type, double-headed type, three-type, long type, grain type.


Commonly used material is 38crMoAIA(nitrogen treatment),it can be changed as per your requirements. According to different usage, the choose for alloy is different, some require for abrasion-resistant while some require for corrosion-resistant. For standard, we have Fe-based, Ni-based, W2C alloy, Tungsten alloy etc for choice

Bimetallic Alloy Materials1)Fe-based alloy 2)Ni-based alloy/Deloro alloy
3)Co-based alloy 4)NiCo-based alloy
5)Tungsten carbide/Wolfram carbide
Double-alloy levelLevel A - containing Tungsten of 40%
Level B - containing tungsten of 25%
Level C - containing tungsten of 15%

Bimetallic screw: Base material 38CrMoAlA, sprayed alloy powder on the screw flight, prolong life of screw.

Bimetallic barrel: Base material 40Cr, casted a 2-5mm wear resistant and corrosion resistant bimetallic layer

on the barrel inner wall, so it has much longer using life than nitrided barrel.

We could design for you for any Genneral plastic materials(such as PP PE ABS AS PS PC PET PA PVC PMMA TPU PU etc.)and Enginneering plastic materials(such as ABS+PC BMC LCP PPS PAR PA-6 PA-66 PA9T PA4T CPVC PVDF POM Glass fiber etc.)
