Extruder screws and barrels are made of high alloy steel (GB 38CrMoAlA / DIN 41CrA1Mo7 / AST M4140). We supply extruder screws and barrels, with options of nitriding and bimetallic treatment, such as hard chroming or sprayed-on hard alloy.

Bimetallic Screws

We offers a Tungsten Carbide Coating for making bimetallic screw and barrel. The coating is applied using PTA spraying system that actually bonds the coating to the base material. The thickness of the applied Tungsten Carbide is approximately 0.8 mm- 2mm, depending on application, with hardness of 62 – 70 RC.
