For our bimetallic screw,we have adopted a new technology of surface hardening process by the whole screw surface.

Excellent anti-erosion and anti-abrasion characters
The bimetall screw and barrel for its excellent anti-erosion and anti-abrasion characters,the bimetallic screw and barrel are widely used in the extrusion lines.With HVOF high speed spraying equipment,spray a layer of metal which melt on the screw surface; a melt-cast method is adopted to get bimetallic barrel,which could conform its precise formation.
