Screw Barre/ Bimetallic Screw Barrel for Plastic PP PE PVC Made in China

Bimetallic screw and barrel feature

The bimetallic barrel is with 2-3mm alloy layer of anti-abrasion and corrosion and high temperature cast on the inner wall, it will be prolong use life for product than nitriding, bimetallic have more abvious advantages when processing special plastic for project plastic, fluoride plastic, ppo etc.
