A Better Way of Joining

We find the best solution for your joining task. For a higher quality, shorter cycle time and lower costs.

Because we consider ourselves a partner for your joining processes. In case of defective joints in the current production as well as in the selection or development of a new joining process we are at your service. Our extensive know-how in processes, materials and application fields is based on many years of practical experience and close cooperation with our research partner ISF. In this way, we combine the best of theory and practice to integrate joining top performance into your production as well as to improve running processes continuously.

Theoretically sound, down-to-earth and flexible.
