Stöferle GmbH

What Stöferle GmbH does

Stöferle GmbH is a German precision manufacturing company headquartered in Laupheim, Baden-Württemberg, operating as a system supplier and specialized subcontractor for the further processing of aluminum die-cast components. Founded in 1992 (with the company's own stated experience base of 25+ years pointing to operational ramp from approximately 1998), the company runs two coordinated entities — Stöferle GmbH and Stöferle Automotive GmbH — from a single Laupheim site encompassing approximately 16,000 sqm of production space and 200+ employees. Its product portfolio spans two main categories: (1) precision-machined engine, transmission, and eMobility housings — including lower crankcase sections, oil pans (notably the OM656 and M264 engine programs), control housings, converter housings with integrated oil coolers, and ISG 2.0 / Hybrid GEN4 drive unit housings — and (2) custom-built Sondermaschinen (special machines) such as rotary transfer machines, 5-axis machining centers, washing systems, 100% leak testing systems, assembly machines, clamping fixtures, handling systems, and automation/robotics solutions developed in-house.

The business model is B2B enterprise manufacturing with a direct-to-OEM and Tier-1 supplier go-to-market motion. Revenue is generated from precision component series production, special machine construction, and full-process system integration including raw material procurement, mechanical processing, washing, leak testing, assembly, and just-in-time delivery. Pricing is quote-based and not publicly disclosed. Customers are exclusively German and international automotive OEMs, with named platform evidence (OM656, M264, ISG 2.0, GEN4 hybrid) suggesting deep tooling and qualification entrenchment with a narrow set of large counterparties. Marketing is conducted primarily through international metalworking trade fairs and the company website (stoeferle-gmbh.com). The company holds IATF 16949:2016 (Kiwa), ISO 9001:2015, ISO 14001:2015, and ISO 50001:2018 certifications, and operates sustainability assets including rooftop photovoltaic installations and a proprietary high-efficiency wastewater treatment system for emulsion recovery and recirculation.

Ownership is private and family-controlled, with managing directors Erich Stöferle, Katja Stöferle, and Luca Battiloro. No venture capital, private equity, or institutional investor involvement is indicated, and no M&A or funding activity is disclosed. The company is actively operating, with no disclosed revenue figure, and remains wholly concentrated in the automotive vertical.
