Bimetallic Screw And Barrel Technology

- Aug 27, 2018 -

Nowadays, bimetal technology is a very important means to increase the service life of mechanical parts. It uses ordinary metal materials as the mother body, while the working surface of mechanical parts is compounded with another layer of special alloy. In order to improve the wear resistance and corrosion resistance of the parts, the service life of the parts is increased. Taking the most economical material structure and achieving the highest economic benefits is the reason why bimetal technology has become a driving force for people in the Plastic Industry
