The welding ist generated in the material through molecular oscillation (frictional heat) heating the material evenly.
Heat output to the welding tool (electrode) and the pressure plate protect the surface while the highest temperature is achieved in the weld, thus creating an optimum joint.
All polar materials such as soft and hard PVC, Polyamide (PA), Polyester (PES), Polyurethane (TPU), some types of TPO and compound materials with enough HF-reactive components can be welded or heated using high frequency.
Non HF-reactive materials, such as textiles, are joined by auxiliary welding films or HF-reactive glues.

-	outstanding weld strength (up to 70% of the basic material)
-	best weld quality through optimum temperature behaviour and cooling under pressure
-	thick films can be welded
-	punching or profile welding (also three-dimensional) can be carried out
-	low energy consumption
