Single- and Twin-Screws
Extruder-Komponenten Salzgitter’s decades of experience and operating excellence manifest themselves in the range of designs of screws supplied by the company.
Its plasma-based welding gives the capability to produce screws whose surfaces are protected against abrasion. Wear-protecting layers are produced comprised of Ni/C-based alloys and specially developed and modified tungsten-carbide alloys.
Nitrided twin-screws are the standard design in use for many applications of extrusion. High-demand applications necessitate the coating of flights. Layers of molybdenum have proven their efficacy in achieving excellent gliding and galling-minimizing characteristics.
