About Us
Stratmann GmbH is a medium-sized, family-owned CNC jobbing manufacturer in the Sauerland (North Rhine-Westphalia) specializing in precision turning and milling technology since 1970. The company produces custom turning and milling parts, as well as turned and milled parts and lamp holder hoses in small to large series on over 50 modern CNC machine tools. The turning technology includes long turning, automatic turning, universal turning and turned and milled parts; in milling technology, cast, profile, laser, or saw cuts are finished, optionally with loading by industrial robots or cobots. Furthermore, Stratmann offers sawing, grinding, deburring, assembly (screwing, gluing, soldering, pressing), component commissioning, logistics, and finishing such as anodizing, powder coating or galvanizing. Steel, stainless steel, aluminum, brass, cast iron, and technical plastics such as POM, PEEK, or PTFE are machined. The structure consists of Klaus Stratmann Metallwaren GmbH (Arnsberg) and Stratmann Frästechnik GmbH (Wickede/Ruhr). Customers come from lighting and light technology, furniture and interior design, electrical engineering, and the leisure industry.
