RELIABLE PARTNER – ALSO FOR THE AUTOMOTIVE INDUSTRY
Since more than 70 years we manufacture high class lever arch mechanisms for the stationery industry. This long-standing experience with metal and its possibilities, our success in tool making as well as in component assembly and our good reputation make us an ideal business partner – also for the automotive industry.
Together with car manufacturers we have developed products suiting the requirements of the automotive industry regarding design, functionality and workability and certified according to ISO 16949. We have let our strengths unfold in early stages of development. The result is a choice of ready-made components which can be adapted and extended for individual use.
