Longitudinal Welding Tried-and-tested technology

Longitudinal vibrating systems are used in many areas, for example for welding plastics and non-ferrous metals. Usually, the welding system is arranged horizontally. The vibrations are tangentially transferred into the upper part to be joined. The sonotrode activates the upper part and moves it horizontally in relation to the lower part. Owing to the high frequency of 20 kHz, the amplitude and the pressure, the resulting friction creates an atomic connection between the two parts. The required pressure is generated using a press.
