About KARP Maschinenfabrik
KARP Maschinenfabrik GmbH in Niederkassel operated as a supplier for mechanical, apparatus, and steel construction, and as a job manufacturer for the mechanical production of large components. The range of services included CNC turning up to Ø 3,200 mm, 8,000 mm length, and 11 t total weight; CNC milling up to 10,000 mm length and 30 t; steel construction and welded structures up to 30 t; as well as completely processed and coated large mechanical components up to 100 t. Furthermore, the company manufactured precision parts using high-speed milling, wire and sinker eroding, micro-precision milled parts, round and flat grinding, and precision welding using laser technology. Design, material finishing, assembly production including painting, acceptance and test run, as well as assembly and commissioning were also part of the offering. All materials were processed, especially specialized, high, and super-alloyed stainless steels. The GmbH was closed on 31.01.2020 for economic reasons; mechanical components can still be sourced or delivered via Wolfgang Antosch in cooperation with long-standing partners. The hall and office spaces at the site have been rented since 01.04.2020.
