Mertens Gruppe

What Mertens Gruppe does

Mertens Gruppe is a German family-owned automotive supplier headquartered in Gütersloh, with operations dating to 1924. The group operates two integrated production sites: the Gütersloh headquarters focused on metal processing (stamping, deep drawing, cold forming, zinc die casting) and the Meerane facility operated by wholly-owned subsidiary KDM GmbH, which specializes in plastic processing (injection molding, 2-component technology, gas internal pressure technology, micro injection molding, EPDM/LSR processing). Both sites also perform surface treatment (painting, galvanic coating) and in-house tool and mold construction, giving the group end-to-end capability from design through series production.

The group's technology stack spans computer-aided design and manufacturing (VISI, Think-design, CATIA, Hypermill), advanced optical metrology (GOM ATOS Triple Scan), and is supported by IATF 16949:2016 quality-management certification at both production sites. Mertens supplies components and assemblies to automotive OEMs; named customers include Volkswagen, Audi, Škoda, SEAT, Porsche, Bentley, and Lamborghini — all brands within the Volkswagen Group. The corporate structure centers on Mertens GmbH & Co. KG, with KDM GmbH as a wholly-owned subsidiary and GTT Technologiezentrum GmbH as an affiliated entity.

The business operates as a tier-level automotive supplier under a B2B contract-manufacturing model, monetizing through component and sub-assembly sales into OEM production lines. Revenue mechanics are anchored in long-cycle automotive program awards, with tooling, prototyping, and series production integrated under one roof to support customer development timelines. Go-to-market is relationship-driven into the VW Group supply chain, with no evidence of a direct-to-end-customer channel or aftermarket consumer product line.
