The principle of ultrasonic welding is to transmit energy vertically to the welding surface by high-frequency vibration to make local high temperature. Due to the poor thermal conductivity of the plastic, the wrinkles in the welded area cause the two plastic contact surfaces to melt rapidly, and a certain pressure is applied to fuse them into one.

1.Ultrasonic spot welding produces strong structural soldering, especially for large parts, extruded or cast thermoplastic sheets, and parts with complex geometries and hard-to-reach joint surfaces.

2.It is used in the automotive industry to weld automotive parts such as batteries, front corner lights, gauges, reflectors, car manuals, welded sheaths, door weld baffles, automotive, automotive floor mat welding, automotive bumper repair welding.

Competitive Advantages:

1.Light weight, easy to carry and easy to operate.

2.Effective energy saving, healthy and environmentally friendly.

3.Equipped with overload protection circuit (voltage, current, phase, temperature, output).


Q:What is the depth of 28K/30K/35K spot welding gun?

A:Depth can be determined based on customer needs and materials. Take ABS as an example, the minimum welding can be 0.3mm, but to achieve better air tightness, it needs to be welded to at least 0.5mm deep.
