Steel Competence – Precision since 1960
ELFA-Maschinenbau GmbH is a manufacturing company founded in 1960 in Mülheim an der Ruhr with over 60 years of experience in mechanical engineering. The company produces individual parts and complex assemblies made of steel, stainless steel and special alloys – from one-off production to small series. The value chain includes CNC-controlled precision machining (turning and milling), welding of all common materials, laser and flame cutting for precise contour cuts, bending for sheet metal working, and turnkey assembly of complete assemblies. State-of-the-art production facilities enable the machining of large parts up to 12 meters in length and up to 5 tonnes in weight. Customers come from the steel and iron industry as well as mechanical engineering. The company is certified to ISO 9001:2015 and ISO 3834-3 and supports projects from technical consulting and design through to on-time delivery.
