What are the characteristics of the bi-alloy barrel screw
　The double-alloy barrel screw is wear-resistant, high-temperature resistant, and corrosion-resistant. It is treated with a unique process, and the alloy layer is inlaid firmly and does not fall off.
　　The characteristics of double alloy barrel screw:
　　 1. The double-alloy barrel screw has the ability of fast non-reverse speed;
　　2. Complete anti-reverse ability to maintain the minimum plastic backflow phenomenon;
　　3, the material flow is smooth, there is no dead angle to avoid local shearing heat, which may cause plastic deterioration;
　　4. The double alloy barrel and screw have abrasion resistance and corrosion resistance;
　　 5. The double alloy barrel screw can be used for a variety of plastics.
