Ultrasonic welding uses high-frequency vibration to locally heat and melt the material to achieve welding. Stationery materials are diverse, such as plastics (PP, ABS), metals (stainless steel accessories) or composite materials (plastic + cloth), and the welding compatibility of different materials needs to be considered.

Secondly, the welding process may include pretreatment (such as material cleaning, alignment), ultrasonic vibration application, pressure-maintaining cooling and other steps. Equipment parameters such as frequency, power, and amplitude need to be adjusted according to material thickness and type.

In terms of advantages, ultrasonic welding does not require glue or screws, improves production efficiency, reduces environmental pressure, and has a firm weld and a neat appearance.
