Friction Stir Welding (FSW)

We have further developed our established PROTO DIE process (prototypes for near-series die-cast components): since last year, we have also been offering our customers die-cast prototypes in combination with the innovative friction stir welding (FSW) process.

Example: Production of a housing for a braking resistor that converts excess braking energy into useful heat, making it ideal for electric and hybrid drives. By combining PROTO DIE with the Friction Stir Welding process, our customer achieved a space savings of over 80% while reducing the weight of the housing.

Friction stir welding, also known as FSW (Friction Stir Welding), is an innovative process. It makes it possible to join materials that are difficult or impossible to weld together due to their special properties.

Advantages of Friction Stir Welding

• Precise processing
• High reproducibility of welds
• Minimal material fatigue and cracking
• More environmentally friendly than conventional welding

The addition of friction stir welding to the PROTO DIE process is of particular interest in housing technology for sectors such as transportation and energy, as well as mobility and logistics, as the combined process can be used not only economically but also in an environmentally friendly manner for pilot and small series.
