The bimetallic barrel for twin screw extruder is a kind of barrel spary a 1-3mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to common nitrided barrel. Bimetal has more abvious advantages when processing high calcium carbonate powder PVC mixture to enhance the abrasion life.

Our company use special alloy powders being sprayed and welded on the top of screw flights, and use different alloys and welding methods for the screw of different functions.
