The manufacture of our screw flights using the cold forming method allows us to obtain screw flights with the best technology on the market. Their thickness is consistent throughout the flighting, providing the highest performance in terms of wear and extending its useful life.

This type of screw flight is ideal for all those applications where wear resistance is important. It is also recommended by manufacturers and engineers to replace continuous lamination screw flights.

Thanks to the combination of our engineering and manufacturing experience, and the exclusive machinery we use to make our screw flights, we can obtain non-circular screw flights. We can supply from conical screw flights (inner or outer edge) to notched, notched and folded flights, or any profile you may need.

As a reference in the world market, HELI-TRANS can offer you the manufacture of screw flights using bimetallic sheet, with a steel or stainless steel base, and with the outer edge of the screw manufactured with the toughest hardfacing materials on the market. These types of screw flights are mainly used in the paper and biomass industries, where durability is the main requirement to reduce maintenance costs of the installation.

Materials:

  • Carbon steel
  • Stainless steel
  • Titanium stainless steel
  • Anti-wear steel
  • Heat resistant (CrNiMo)
  • Bimetal (steel or stainless steel based)
  • Etc.

Consistent thickness, from 3 to 50 mm.
