Screw and barrel

We undertake the renovation, replacement, remanufacturing of single or twin-screw extruders of any kind as well as pulley or cylinder units according to samples or drawings of injection molding machines in wide size range. We can also help our customers in case of processing problems, since we undertake the modification of pulley profiles and help optimizing the type of materials used.

These are prepared in two main designs:

  • Nitrided: for general use, for pure granulate
  • Bimetallic: recommended for high abrasion resistant, fiberglass, calcium, and other filling materials, or in case of recycled granulate
  • For special needs: stainless, tempered, coated surface protection

Manufacturing of supplementary elements:

  • Hopper, connecting disks for cylinders
  • Mixing tip for extruder pulley
  • Closing units for injection molding pulleys
  • Twin-screw pulley or cylinder segments
