Bimetallic Screw And Barrel
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.
