Ultrasonic Welding1. PrincipleUltrasonic welding uses high - frequency mechanical vibrations (usually above 20 kHz). The ultrasonic transducer converts electrical energy into high - frequency mechanical vibrations. A sonotrode (also known as a welding horn) transmits these vibrations to the parts to

Rapid heating of the workpieceHigh - frequency welding uses high - frequency electrical energy, usually in the range of radio frequencies (from a few kilohertz to several megahertz). When the high - frequency current is passed through the workpiece or the area to be welded, it induces eddy currents

A high - frequency welding machine is a device with a wide range of applications:1. Welding of metal materialsSheet metal welding: It is commonly used to weld thin - walled metal sheets. For example, in the production of metal cabinets, such as file cabinets and electrical equipment enclosures. The

PrincipleHigh-frequency (HF) welding of plastics is very often applied whenever PVC and PU products have to be welded. Well-known products whereby HF welding is applied are car mats, baby cushions/pillows, screen canvas, waterbeds, inflatable boats, drip and blood bags, deck canvases, conveyor belts
