Electromagnetic Resistance Welding The EWS method

The EWS process particularly concerns the subsequent installation of metallic components and threaded inserts in plastic parts.

The heating here and thus the plastification of the joining zones are made indirectly by non-contact heating of an available metallic component using electromagnetic energy. Thus, plastic parts with three-dimensional joining zones can also be welded.
The characteristics
– Non-contact heating of the metal components

– Exact provision of the necessary energy consumption

– Exact reproducibility of the insert temperature

– Low thermal load of metal + plastic

– Shortest possible heating times

– Shortest possible cooling times using cold insert punch

– Insert tolerances smaller than 0.1 mm

– No material damage due to overheating

– No hot machine parts

– Deep heating of the metal components using low frequency
