Crested shear knives, long knives, profile shear knives, circular knives and rubberised ejector rings for steel production

High quality without compromise: Our knives for steel production

State of the art machines, tightest tolerances

Machine knives for use in steel production are challenging from a production engineering point of view and place enormous demands on quality. A knife change always entails a long and thus costly system shutdown; consequently, long knives and circular knives from our company are characterised not only by very high accuracy, but also by their extreme resistance to wear. In the past, we have made serious investments in our machine fleet, in order also to produce to the most complicated geometries and tightest tolerances. In addition to standard qualities, we also deliver special qualities for particular stress at high temperatures.

Perfect team: Our knives and your machine

We produce crested shear knives, long knives, profile shear knives, circular knives and rubberised ejector rings for all the major machine manufacturers, inter alia for SMS Group, Sundwig, Andritz, Danieli and BWG.
