Bimettallic barrel and screw
Product Description
Bimetallic barrel barrel wall in a layer of 2-3mm welding of wear-resistant corrosion-resistant, high temperature alloys, and its effective service life than ordinary barrel nitride greatly enhanced to increase the wear life. For the processing of engineering plastics, polysulfone, PPO special type of plastic, PVC formulations, such as high Calcium powder, the superiority of dual-metal especially.
Substrate outer cylinder: 40Cr, 45 # steel; alloy thickness :1.5-4mm; luster: excellent
Bi-metal screw from the previous PTA welding alloy, update equipment used high-pressure speed (HP / HVOP) alloy coated comprehensive technology of the spraying. Corrosion-resistant alloy WPT1 applicable to nylon, PVC, PC, PMMA, etc., WPT2 wear-resistant alloy for high temperature resistant nylon fiber, and magnetic, aluminum-magnesium powder, injection, such as bakelite. WPT3 both WPT1, WPT2 two properties, wear-resistant high temperature corrosion resistance.
