Screw Barrel

Wear-resistant screw and barrel sets machined to your extruder's specification, restoring melt quality and output on machines running worn components.

The screw and barrel set is the heart of any extruder, and a worn set is usually the real reason behind falling output, uneven melt or rising scrap rates — even when everything else on the line looks fine. We manufacture replacement Screw Barrels machined to your exact extruder specification, so fit and performance match what the machine was designed for.

Surfaces are hardened and, where needed, bimetallic-lined for extended wear life against abrasive or corrosive polymers such as filled or recycled compounds. Each set is built to restore proper melt homogeneity and pressure profile rather than just being a generic replacement part.

Available for single-screw and twin-screw extruder configurations, supplied either as a matched pair or as individual components depending on what your machine needs replaced.

  • Machined to your exact extruder specification for a precise fit
  • Hardened, bimetallic-lined options for abrasive or corrosive polymers
  • Restores melt homogeneity and pressure profile on worn machines
  • Available for single-screw and twin-screw configurations
