What Kummer does

Kummer GmbH & Co. KG is a German family-owned precision manufacturing supplier headquartered in Ötisheim, Baden-Württemberg, founded in 1977 and operating for over 45 years. The company provides a vertically integrated one-stop capability spanning construction, toolmaking, stamping, injection moulding, and assembly under one roof, with approximately 50 toolmakers and mould makers in the toolmaking department and an apprenticeship track that has taken on more than 130 apprentices over 40+ years. Its technological centrepiece is the proprietary Progressive Injection Moulding (Folgeverbundspritzen) process — developed in-house approximately 20 years ago as a further development of the reel-to-reel method — which combines stamping and partial plastic overmoulding in a single machine for hybrid metal-plastic parts. The portfolio also includes the EloPin® press-fit contact technology (manufactured under licence from patent holder TBS Sorig with 15+ years of production experience), SLM additive manufacturing of contour-cooled mould inserts in tool steel 1.2709, and tool-integrated processes such as thread forming, wire riveting, silver contact welding, and 100% inline camera inspection.

The company operates as a direct B2B enterprise supplier to industrial customers in automotive, electrical/electronics, industrial, e-mobility, medical technology, and aerospace sectors. Pricing is custom and quote-based, with multi-year development contracts reflecting Kummer's positioning as a partner from concept through series production. Revenue is generated primarily through hardware sales of precision stamped parts and EloPin® components, supplemented by professional services revenue from custom tool design. The company is privately held with no external institutional investors, managed by Wolfgang Hofmann and Jens Hofmann, and holds IATF 16949:2016, ISO 9001:2015, DIN EN ISO 14001:2015, and DIN EN ISO 50001:2018 certifications.

• TBS SorigcoreTechnology or IntegrationTBS Sorig is the original developer and patent holder of the EloPin® press-fit technology. Kummer manufactures EloPin® pins under licence from TBS Sorig. The patent protects the function and shape of the pin, but not the manufacturing process, allowing Kummer to develop and improve its own production methods.
