We also can customize according to clients' requirement.

Screw structure and compression ratio can be designed according to different products and raw material.

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

Bimetallic barrel: Base material 40Cr, melt-casting 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.

Base Materials:	1)38CrMoAlA(SACM 645) 2)40Cr
Bimetallic Alloy Materials:	1)Fe-based alloy 2)Ni-based alloy 3)Co-based alloy 4)Tungsten carbide
