For its excellent anti-erosion and anti-abrasion characters, the bimetallic screw
And barrels 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.
