Heidenreich & Harbeck Casting

What Heidenreich & Harbeck Casting does

Heidenreich & Harbeck Casting GmbH is a privately held German iron foundry headquartered in Mölln, Schleswig-Holstein, with a second foundry footprint in Tangerhütte (TechnoGuss GmbH, acquired out of insolvency in August 2015). The company manufactures cast iron components in EN-GJL (gray cast iron) and EN-GJS (ductile cast iron) using sand casting processes, with part weights ranging from 50 kg to 16,000 kg. Its customer base spans agricultural machinery (notably AGCO, for which it received the 2017 Global Supplier Award in Quality and Delivery Performance), printing and tool machinery, wind power (gear housings via subsidiary MBM), and general mechanical engineering.

The business operates a complete in-house value chain: engineering development services (including topology optimization and casting simulation), pattern making via 3D CNC milling, the foundry itself, and downstream mechanical large-part machining through its MBM Mechanische Bearbeitung Mölln subsidiary. This integrated model, anchored by 40-plus years of metallurgical expertise and supported by ISO 9001:2015 and ISO 50001:2018 certifications, positions the company as a single-source supplier of ready-to-install cast components. In-house verification capabilities include FKM guideline strength testing and a Leitz coordinate measuring machine with a 3 x 2 x 1.6 m working envelope.

Revenue is generated primarily through one-time B2B contracts for manufactured castings and machined components, supplemented by professional services revenue from development, feasibility studies, and pattern making for external customers. Go-to-market is enterprise field sales — direct relationships led by CEO Stefan Maier and Sales Director Irina Rot — supported by trade show participation (notably CastForge in Stuttgart), a company website relaunched in November 2024, and limited social media presence. Pricing is quote-based and not publicly disclosed. The company is closely held, with no institutional investors, no parent company, and no identified funding rounds.
