Bimetallic barrel (for injection machine):

Bimetallic screw (for injection machine):

Nozzle,Tip,End Cap (for injection machine):

Tip,ring,check valve (3 pieces) for injection screw:

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

Bimetallic barrel: Base material 40Cr, casted a 2-4mm 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.)

The compression ratio of the screw canbe designed according to different products and mixtrues.
