What Eisenwerk Martinlamitz does

Eisenwerk Martinlamitz GmbH is a privately held German iron foundry headquartered at Eisenwerk 2, 95126 Schwarzenbach/Saale, Bavaria, near the Czech border. The site has been engaged in metalworking since the year 1200 as a hammer forge, converted to an iron foundry in 1856, and registered under its current name in 1932. Under Managing Director Barry Thomas Irvin — a US citizen — the company has invested approximately EUR 67 million in facility expansion, new equipment, and innovative technologies, and operates a fully automated HWS-Seiatsu Full Automatic Molding Machine with a box size of 1200mm × 800mm × 320/320mm, complemented by an automated HWS Gießlok pouring carriage (2023), a RUMP shot blasting system, a hydraulic multi-stamp press, and a Tornado crucible extraction hood. Annual production exceeds 50,000 tonnes of castings and the company delivers to 17 countries.

The company's product portfolio centers on ductile (spheroidal graphite) iron castings in EN-GJS grades 400-18 LT/RT, 500-7, 600-3, and 700-2, and gray (lamellar graphite) iron castings in EN-GJL-200, 250, and 300 grades per DIN 1561, delivered as rough castings, machined components, or assemblies in the 20 to 300 kg weight band. Value-added services include in-house pattern building (conventional or CNC 3D-form-milled from CAD datasets), casting process simulation for gating/riser design and metallurgical optimization, and technical consultation. Customer industries span agricultural machinery, axle producers, building/construction machinery, commercial vehicles, hydraulics, manufacturing systems engineering, railways, renewable energy (wind turbine gearbox housings), and robotics. The company is sales-led and direct-to-customer, emphasizing just-in-time delivery and quality assurance as the basis of long-term B2B relationships that run from product planning through delivery.

The revenue model is straightforward B2B hardware sales of cast iron products, with pricing determined per quote based on specifications, materials, weight, machining, and volume. The company holds ISO 9001 quality, ISO 14001 environmental, and ISO 50001 energy management certifications, a Deutsche Bahn railway certification, and a Lloyd's Register certification, and operates a single Integrated Management System since 2019. No external investors, parent companies, or venture capital ownership are indicated; the company is independently held, led by Irvin, and self-funded.
