Overview
Custom knives for metal cutting and processing
SIKNIVES for Metal Industry are custom-manufactured industrial knives and wear parts for metal cutting and processing. They are used in rolling mills for hot and cold rolled sheet metal and plate mill applications, and in pipe and tube mills for black, cold rolled and stainless steel pipes.
In steel service centers and processing lines they serve pickling, galvanizing, tinning, painting and cold reduction lines, including side trimming, scrap chopping, sanding and cut-to-length operations. They also cut copper and aluminum in non-ferrous processing, and bars, beams, profiles and wires in long product mills.
SIJ Ravne Systems focuses on material selection, heat treatment and high-precision machining to meet market demands and improve cutting performance.
