WEFA was founded in 1972 as a subsidiary of Alusuisse. After going through a change of ownership and realigning its strategy, the company began to specialize exclusively on the production of aluminum extrusion dies. Their products are used in the automobile and construction industries as well as in electrical engineering. With the development and subsequent patenting of their own coating process, WEFA made the leap to become the global market leader in the area of coated dies. Their customers include leading aluminum companies and innovative medium-sized pressing plants. Currently, the company has five locations worldwide and employs over 200 people.
