Excellence in 3rd generation

DWL-WOLF GmbH was founded in 1978

Today, DWL-Wolf operates three production sites as a supplier to the steel and foundry industry. The head office and administrative center is in Lüdenscheid, where we focus on the production areas of forging and sheet metal processing.

In the forge, we produce all kinds of foundry tools, such as pouring ladles, skimmers, plungers, foundry tongs and special items according to customer requirements.

The second plant in Lüdenscheid manufactures sheet metal products, in particular ramming forms for the refractory lining of induction furnaces.

The Niederkrüchten production plant manufactures insulating and exothermic products for ingot casting in steelworks and foundries. These include hot-tops, lining-chains, and covering boards, specially tailored to customer requirements.
