Detailed Photos

Bimetallic Screw:

Strong abration resistance, good for the 30% glass fiber and reworked materials.

Super hard alloy of high density, low porosity and high hardness.

Uniformity heating of power and low strength pressure.

With high corrosion resistance, high wear resistance and high temperature resistance 

Bimetallic Barrel:

2-5mm-thick alloy coat on the barrel inner wall

Excellent corroion resistance, abrasion resistance and high working temperatre.

Useful service life is greatly improved

Able to process special plastic to enhance the abrasion life, such as engineering plastics, fluorine plastics, PPO, and tec.
