Ultrasonic spot welding technology

When ultrasonic waves act on the surface of thermoplastic plastics, they generate high-frequency vibrations of tens of thousands of times per second. The ultrasonic energy is transmitted to the welding area through the welded component, resulting in local high temperatures. Due to the poor thermal conductivity of plastic, heat accumulates in the welding area, causing the plastic surface to quickly melt. After applying a certain amount of pressure, it melts together.

Handheld ultrasonic spot welding machines can be used for welding, riveting, spot welding of films, fabrics, thermoplastic products, as well as inlaying and edge pressing processes between metal and plastic parts
