Coswig

What Coswig does

Walzengießerei Coswig GmbH, operating under the brand COSWIG GUSS, is a German specialty foundry founded in 1892 and headquartered in Coswig, Saxony. The company is a wholly-owned subsidiary of the DiHAG Integrated Foundry Group, a network of 12+ subsidiary foundries operating across Germany and Europe. Coswig employs more than 260 qualified specialists and operates one of the most modern foundries in Europe, with annual production capacity of 40,000 tons across two independent production lines and a maximum piece weight of 55 tons. Its 125+ year history includes the founder's 1895 invention of the world's first hot blast cupola furnace and the 2003 development of hollow rotor shafts for the world's first 5 MW wind turbine.

Coswig operates two core product divisions: roll casting (Walzenguss) and hand mould casting (Handformguss). The roll casting division produces profile rolls, upsetting rolls, rolling rings, and pistons for rolling mills, hot strip mills, and hydraulic press systems, with proprietary materials including graphite-free running surface pistons (480-550 HV) and high-chrome wear-resistant alloys. The hand mould casting division produces components for wind turbine drive trains (hollow rotor shafts, bearing housings), industrial mills and grinding systems (roller bodies, grinding plates, tension frames), and general mechanical engineering (gearbox housings, machine beds, printing cylinders). In-house R&D (established 2000) develops proprietary alloys including ceramic-metal casting composites, solid solution strengthened cast iron (EN-GJS-450-18 / EN-GJS-500-14), and NiHard (EN-GJN-HB555), supported by research partnerships with Fraunhofer IKTS, TU Bergakademie Freiberg, and TU Dresden. The company maintains ISO 9001, 14001, 45001, and 50001 certifications, plus Germanischer Lloyd and Lloyd's Register qualification for marine and offshore applications.

Coswig generates revenue primarily through custom hardware sales of engineered castings, with pricing negotiated per-project based on customer specifications. The go-to-market is enterprise field sales, complemented by international sales agencies in France, Benelux, Italy, Spain, Poland, Brazil, India, and Turkey, with products exported to over 20 countries. Products are delivered ready-to-install, and engineering services (casting-compatible design, material selection, solidification simulation) are bundled with product delivery. Named customers include ThyssenKrupp, Koenig & Bauer AG, and Senvion. The company is led by CEO Viktor Babushchak.
