What Egon Grosshaus does

Egon Grosshaus GmbH & Co. KG is a German family-owned precision metal stamping supplier headquartered in Lennestadt-Bonzelerhammer, with a secondary production facility in Győr, Hungary. Founded in 1935 and now in its third generation of family leadership under managing director Patrick Großhaus, the company operates four production sites in Germany and one in Hungary, employing over 500 people. Its core manufacturing competencies span three integrated technologies — Stanztechnik (stamping, 50–630 tons), Feinstanztechnik (fine stamping, 100–450 tons), and Stanzbiegetechnik (stamp-bending, 30–100 tons) — covering material thicknesses from 0.3 mm to 8 mm across steel, aluminum, stainless steel, and non-ferrous metals.

The company offers an integrated value chain from product and process development through in-house toolmaking (using Siemens NX CAD/CAM/CAE with FEM simulation), prototyping, serial production, and downstream further processing including welding, riveting, clinching, deburring, washing, and surface treatment (KTL, powder coating, galvanic zinc systems). It is IATF 16949, ISO 14001, and ISO 50001 certified across its German and Hungarian locations. Customers include Autoliv, Bosch, Brose, Ford, Magna, MAHLE, Mercedes-Benz, SEG Automotive, and Toyota Boshuko — predominantly tier-one automotive suppliers and OEMs — with additional presence in electrical, mechanical engineering, and sports/leisure verticals.

Grosshaus operates a B2B enterprise field-sales motion with direct sales from its German headquarters and representation in the UK (Autotec Marketing), China (Shenzhen), and Australia (Sydney). Revenue is generated through quote-based, negotiated long-term serial supply contracts for custom-engineered precision components and assemblies; pricing is not publicly disclosed. The company also receives revenue from tooling engineering services and value-added assembly work. Geographic reach spans Germany, Hungary, the United Kingdom, China, and Australia, with manufacturing concentrated in Germany and Hungary.

Core offering

Egon Grosshaus GmbH & Co. KG is a German contract manufacturer that produces precision metal components and sub-assemblies via stamping (Stanztechnik), fine stamping (Feinstanztechnik) and stamp-bending (Stanzbiegetechnik), supported by in-house tool construction, product and process development, prototyping, and further processing/assembly. Output is serial-manufactured parts supplied primarily to automotive, electrical, mechanical engineering and sports/leisure industry customers.

Product overview

Egon Grosshaus GmbH & Co KG operates as a metalworking company offering a portfolio of three core manufacturing technologies: Stanztechnik (stamping, 50-630 tons), Feinstanztechnik (fine stamping, 100-450 tons), and Stanzbiegetechnik (stamp bending, 30-100 tons), which form the foundation of their production capabilities. These manufacturing technologies are complemented by Baugruppen (assemblies) for pre-assembled component groups. The company provides integrated engineering services including Werkzeugbau (tool construction), Produkt- und Prozessentwicklung (product and process development), and Prototypenbau (prototype construction) using Siemens NX CAD-CAM-CAE systems. Secondary services include Weiterverarbeitung & Montage (further processing and assembly) covering welding, deburring, washing, and surface treatments. The integrated offering combines development, manufacturing, logistics, and quality management to deliver complete solutions from product concept to serial delivery.

Products and services

• Stamping technology (Stanztechnik) Serial production of metal components using stamping technology, offered as a contract-manufacturing service to industrial customers.
• Fine stamping technology (Feinstanztechnik) Serial production of high-precision metal components using fine stamping technology, targeted at customers requiring tight tolerances and complex geometries.
• Stamp-bending technology (Stanzbiegetechnik) Combined stamping and bending of metal parts in a single operation, used as a contract-manufacturing service for complex three-dimensional stamped metal components.
• Tool construction (Werkzeugbau) In-house design, manufacturing and maintenance of stamping, fine-stamping and stamp-bending tools (progressive and other tool types) for customer part production.
• Further processing & assembly (Weiterverarbeitung & Montage) Post-forming processing and assembly services for stamped metal components, offered to reduce customer handling and supply-chain steps.
• Assemblies (Baugruppen) Contract-manufactured sub-assemblies built from stamped, fine-stamped or stamp-bent metal components for industrial end-products.
• Product and process development (Produkt- und Prozessentwicklung) Engineering service covering the co-development of metal parts and the corresponding forming and assembly processes, including CAD design, FEM simulation and process optimisation.
• Prototyping (Prototypenbau) Prototype manufacturing of stamped, fine-stamped or stamp-bent metal parts to validate designs before series production.

Direct peers

• Waldaschaff Automotive: German automotive supplier specializing in precision stamping and assembly of structural and safety components. Comparable in technology (stamping, fineblanking) and customer profile, particularly with European OEMs.
• Seissenschmidt: German automotive supplier of precision-forged and machined chassis, drivetrain, and safety components. Comparable as a mid-sized German automotive metalforming tier supplier with similar customer overlap (tier-1s and European OEMs).
• Hirschvogel Automotive Group: Family-owned German automotive supplier of forged and machined steel components (including precision parts for drivetrains and chassis). Comparable as a German Mittelstand automotive metals supplier with strong European OEM customer base.
• Kirchhoff Automotive: German family-owned automotive supplier specializing in metal forming (stamping, welding) of structural and chassis components for global OEMs. Closely comparable in customer base, technology stack, and family-business profile, though larger and more global.
• Muhr und Bender (MUB): German Mittelstand automotive tier-1/tier-2 supplier of precision stamped and formed metal components, headquartered in Attendorn (same Sauerland region as Grosshaus). Comparable in size, customer mix (European OEMs), and stamping technology focus.

Broad incumbents

• Voestalpine Automotive Components: Austrian-listed division of Voestalpine producing precision steel components and assemblies for the automotive industry. Comparable on precision steel processing and automotive customer mix; part of a much larger steel and materials group.
• Schuler Group: German-headquartered global leader in press technology and metal forming; supplies both stamping presses and contract manufacturing services. Comparable on stamping technology; substantially larger and more diversified across press equipment and contract manufacturing.
• Gestamp: Spanish-listed global automotive metal components specialist in stamping, welding, and assemblies. Comparable core business (automotive stamping), but substantially larger with global manufacturing footprint including China, Americas, and Europe.
• Benteler Automotive: Austrian-headquartered global automotive supplier with metal forming, chassis, and module capabilities. Comparable on stamping technology and European OEM customer base; much larger and broader in scope.

Regional players

• Martinrea International: Canadian-listed automotive metal forming and assemblies supplier primarily serving North American OEMs. Comparable business model (automotive stamping and assemblies); serves a different geography than Grosshaus but offers a useful international benchmark for the precision stamping tier.
