About HEOF

Hellwig & Offermann GmbH (HEOF) was founded in 1983 as a machine and gearbox manufacturing company and is based at its headquarters in Ennepetal. The company combines two areas of expertise under one roof: its own CNC machining as well as a manufacturer-independent gearbox service including repair. In the machining field, individual parts as well as small and medium series are produced – boring mill, milling and turning operations, including on large and complex components weighing up to 5 tonnes. In the gearbox service, industrial gearboxes are inspected, repaired and documented, including technical assessment and remanufacturing of no-longer-available spare parts according to drawings or samples. Customers come, among others, from mechanical and plant engineering, the paper and sugar industries, the chemical industry, the steel and rolling mill sector, as well as crane and conveying technology and power generation. A quality management system according to ISO 9001 is verifiable.
