Prototyping What we create: Tailored components and car bodies.

Our construction department creates well-thought prototypes from development studies and ideas. Equipped with the cutting-edge manufacturing technologies, about 95 employees work on a production surface of 11,600 m². Production is performed order-related either manually for individual components, or automated for small series.

Besides the construction of concept car bodies or vehicle components, our competences cover the manufacturing of sheet metal parts and milled parts. We are familiar with the automotive, railway and aerospace industry.

 

We have the following skills in the area of prototype construction:

Mechanical machining / sheet metal forming Complex and precise parts in short cycle times

Milling, turning and bending

Mechanical machining is performed with cutting-edge technologies. A CNCN controlled folding/bending bench is used in order to achieve a repeatable manufacturing of folded and bent parts. Exhaust systems are manufactured with a CNC tube bending machine.


Sheet metal forming

In sheet metal forming, the component is manufactured by bringing a level sheet into its final shape. The material receives the required shape only by plastic deformation, without cutting processes.


Thanks to cutting-edge hydraulic presses and folding benches we are able to manufacture your sheet metal parts with a pressure force of 10 to 1,200 tons.
