dosing and feeding

HELIX has been a competent partner of machine manfacturers for the production of dosing and feeding screws for many years. In this field HELIX specialises in the manufacturing of screws made from a solid rod (i.e. not welded) with a length of up to 3000 mm.

There are multiple uses for screws in the following applications:

  • Food packaging
  • Pharmaceutical packaging
  • Dosing of plastic granulate in extruders
  • Food processing
  • General dosing and feeding of bulk material

Some of the materials used:

  • Corrosion resistant stainless steels like 1.4305 AISI 303, 1,4404 AISI 316L, 1.4453, 1.4571 AISI 316Ti, etc.
  • Nitrided steel for hardened screws
  • C45, St50, ETG100
  • Teflon, polyamides and other plastics

The surface quality of a screw is decisive for the process safety during the feeding process. HELIX delivers:


  • High gloss polished – for optimal dosing results
  • Electrochemically polished – specifically for pharmaceutical and food technologies
  • Micro-compacted – for deadhesive surfaces
  • Hard chrome plated – resistant to corrosion and protected against wear.
