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.
