What Lintorf Iron Foundry does
Lintorfer Eisengießerei GmbH, operating under the brand "Lintorf Guss," is a German industrial foundry founded in 1909 and headquartered in Ratingen-Lintorf. The company has specialized for over 60 years in the manufacture of permanent molds (Kokillen) and accessories for steelworks, including rolling block molds (Walzblockkokillen), forging block molds (Schmiedeblockkokillen), bloom/billet molds (Brammenkokillen), round molds (Rundkokillen), and complementary accessories such as matching plates, counter-plates, bases, funnels, and hoods. It pioneered the sustained use of ductile cast iron (GJS) for Kokillen in 1967 and continues to work with three proprietary material grades — GJS, GJL (gray cast iron), and GJL/SE (special cast iron with elevated carbon for improved thermal conductivity) — selected to optimize mold performance under extreme thermal cycling conditions.
Production is anchored by a 32-tonne and a 12-tonne network frequency furnace, with annual capacity up to 24,000 tonnes and single-piece mold weights up to 25 tonnes. The company integrates the full production chain under one roof: consulting and CAD-based design proposals, in-house model building (Modellbau), foundry casting, and mechanical processing. Modern laboratory equipment, including a spectrometer for chemical analysis and a combustion analyzer for carbon content, supports material compliance and quality assurance, with the operation certified to ISO 9001:2015, ISO 14001:2015, and ISO 50001:2018.
Revenue is generated through direct B2B enterprise sales to steelworks, steel producers, and industrial foundries, both domestically and internationally. Pricing is custom and project-based, with no disclosed list pricing or e-commerce channel — consistent with the bespoke, engineering-driven nature of the products. Lintorf has been a wholly owned subsidiary of the DiHAG Integrated Foundry Group since 2001, a European foundry conglomerate comprising 14 independently operating subsidiaries; DiHAG itself was acquired in 2021 by Oleksandr Petrov and DRK Consulting GmbH. The company is led by Geschäftsführer Viktor Babushchak and Dipl.-Ing. Gunnar Jentsch.
