Bimetallic Barrels for Plastic Machinery
Harden Machinery supplies bi-metallic barrel for high corrosive and high abrasive materials. A layer of tungsten carbide alloy is pasted on the ID of the barrel using centrifugal casting process. The wear resistance layer greatly increase the life of barrels. For screws, optional chrome coating and WC spray welding on flights are available.
