What Siebenwurst Gmbh & Co. Kg does

Christian Karl Siebenwurst GmbH & Co. KG Modellbau & Formenbau is a family-owned German industrial company founded in 1897 and headquartered in Dietfurt an der Altmühl, Bavaria. The company designs and manufactures high-precision injection molding tools, die-casting and pressing molds, and design models, serving primarily automotive OEMs (Audi, BMW, Porsche, Ford) and Tier 1 suppliers (e.g., International Automotive Components) with molded plastic and aluminum components for vehicle interiors, exteriors, and structural modules. Its proprietary process technologies, including the FIT-Hybrid (Fluid Injection Technology), Twin-O-Sheet (Organoblech), and 3D Hybrid methods, were developed through BMBF-funded research consortia with partners such as Audi, Porsche, Neue Materialien Fürth, FAU Erlangen-Nürnberg, and TU Dresden, with claimed market leadership in Organoblech tooling (approximately 50 tools built). The group also operates the Tool Doctors mobile after-sales service (maintenance and repair of own and third-party tools at customer sites), is certified to ISO 9001, ISO 14001, ISO 50001, and TISAX, and has repeatedly won the Fraunhofer IPT 'Werkzeugbauer des Jahres' award (2009, 2012, 2018).

The group operates a federated network of wholly-owned subsidiaries: erocut Funkenerosions GmbH (wire-EDM), Siebenwurst Consulting & Services GmbH (engineering services), Siebenwurst Werkzeugbau Zwickau GmbH (tool production), plus majority-owned CAD/CAM Solution Sp. z o.o. (Poland, 2014), SOLID solutions in design GmbH (product development, Munich/Greenville, 2016), and a minority stake in Infinite Technologies (Poland, 2019). International service and sales entities include Siebenwurst CADCAM Solution S. de R.L. in Querétaro, Mexico (2014), Siebenwurst Tatematsu Mexico, Siebenwurst US Inc. in Greenville, SC (2016), Siebenwurst US Inc. Toccoa, and three China locations (Shanghai 2011, Shenzhen, Shenyang). Group revenue was reported at €85M in 2017 with 700 employees, with a publicly stated medium-term revenue target of €100M. The current homepage references ~400 employees worldwide.

Siebenwurst sells exclusively through direct enterprise field sales (no intermediaries), with named account leadership (Marc Binder, Head of Sales; Daniel Maier, Research & Sales). Revenue streams comprise (1) one-off engineering and tooling projects for OEMs and Tier 1s (the dominant stream, quote-based pricing for custom mold manufacturing), (2) product development services via SOLID solutions in design GmbH and Siebenwurst Consulting & Services GmbH, and (3) the Tool Doctors after-sales service that monetizes post-project maintenance and repair. Customer concentration is in the automotive vertical, with non-automotive (household appliances, environmental technology) and emerging aerospace (HyFiVe) as secondary segments. There is no publicly disclosed pricing model; commercial engagements are project-based with confidentiality typical in the German Mittelstand.
