Bimetallic screw Bimetallic barrel

The bimetallic barrel is a kind of barrel with a 2-3mm-thick alloy 

coat on the barrel inner wall which has the ability to resist abrasion,

erosion and high-temperature. And its useful service life is greatly improved contrast to common nitrating barrel. Bimetal has more obvious advantage when processing special plastics such as engineering plastics, fluoride plastics, PPO, etc.
