About SiegTec GmbH
Who we are
SiegTec GmbH is an owner-managed machining specialist based in Mudersbach in Siegerland (Siegen area). Based on over 30 years of experience, we produce high-precision turned and milled parts made of stainless steel (V2A/V4A), titanium, non-ferrous metals, tool and tempered steels as well as cast and light metal materials. Our core competence is CNC turning, including complete processing (turn-milling combination) — from individual parts and prototypes to small and medium-sized series. At Plant 2 in Werdohl, which was acquired in 2024, we are adding series processing of cast components. Among other things, we supply mechanical and special machine construction, hydraulics and hydrotechnology, the chemical and food industry, medical technology, measurement and control technology, energy and plant engineering, as well as aerospace and motorsport. As a reliable manufacturing partner from Siegerland, we combine modern machinery with brief, cooperative coordination — for reproducible quality according to the drawing.
