Why are bimetallic barrels used today?

The today's processing of modern plastics with fillers and fibers requires modern machine equipment. In the area of the plastification process this was taken into consideration through the development of most up-to-date wear resistant systems.

The blank barrel is coated with an alloy (via spin casting) and then finished.
  • Lower wear resulting in higher process stability 
  • Combination of wear and corrosion resistance
  • Based on the processed plastics, the correct wear protection system is chosen.
Bernex is offering various bimetallic inlays against all types of wear:
  • Abrasion (A110)
  • Corrosion (C242)
  • Combined wear of corrosion and abrasion (AC333)
