Competent
Our qualified team has 25 years of experience and can offer a proven solution
Agile
Thanks to our high real net output ratio, we are flexible and independent; we focus on fulfilling YOUR wishes
Our Services

Development
We would be happy to assist you with the design of your product in a way that is suitable for welding and to work with you to develop a suitable production concept.

Assembly
We also provide complex production systems from a single source, commissioning is carried out by our trained staff. Thus, the machine you receive is “ready to go”.

Service
Our service team supports you worldwide via remote diagnosis, as well as personally on-site.
Current

Circular friction welding - CircleMerge
PolyMerge optimises circular friction welding of small and non-symmetrical components, e.g. for electronics, sensors and actuators

Infrared welding redesigned
Infrared welding is a well established welding technique for polymers. The method offers clearly multiple advantages over a contact based heat mechanism. Both, systems based on metal foil and based on glass emitters suffers from systematic limitations. Surprisingly the technologies has not changed for a decade, this was reason enough for us, to develop a modern alternative:
Our work leads into a setup based on ceramic emitters produced in an 3D printing process. The result is: flexible in design, high emitter performance, superb lifetime…

Flexible tank production
Demonstration of a robot-based tank production plant for the flexible machining of fuel tanks. The machine has a camera system for automatically detecting the welding position and a thermal camera for quality control.
