Bimetallic Screw and Barrel - SJ

Specifications:
For our bimetallic screw, we have adopted a new technology of surface hardening process by the whole screw surface instead of only hard facing the screw flights by PTA treatment.
For bimetallic barrel, we have raised its tungsten carbide content to 30%and 50% from the previous 10% of tungsten carbide and increased the processing length to 4000mm from the previous length of 3000mm.
Bimetallic barrel in the barrel wall casting a layer of 2-3mm.
Wear and corrosion resistance, high temperature alloy, its useful life longer than the average nitride barrel greatly enhance the processing of engineering plastics, fluorine plastic, polysulfone, the ppo special type of plastic, etc., especially the superiority of the bi-metallic.
For the different functions of the screw, using different alloys and welding.
