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.
