We own a unique technology of cold forming of screw blades, thanks to which we also offer deliveries of individual screw segments. We guarantee their maximum geometric accuracy of the screw segment, especially the accuracy of its pitch, which has a major impact on the resulting pressures and, in the case, of screw pressing machines and the quality of pressing not only structural and stainless steels but also other abrasion resistant materials such as Hardox 400.
Depending on the subsequent use in a specific environment, screw segments can be provided with anti-wear protection , which optimizes their service life. The most common method is hardfacing based on chromium and tungsten carbides . Another protection method is a method developed by us called AWELD Ceram that is based on ceramic plates. We use abrasion-resistant steels HARDOX, Cruesabro, etc. for the requirements of the best possible sliding properties of screw surfaces.
