When the ultrasonic wave acts on the thermoplastic plastic contact surface, it will generate tens of thousands of high-frequency vibrations per second. This high-frequency vibration transmits the ultrasonic energy to the ultrasonic welding material surface through the ultrasonic mold, so the material will generate high temperature. As a result, the contact surfaces of the two plastics melt rapidly, and after the pressure of the ultrasonic machine is added, they are integrated and solidified. In this way, the purpose of ultrasonic welding is achieved. The welding time and ultrasonic welding head pressure of the ultrasonic welding machine can be adjusted, and the ultrasonic amplitude is determined by the transducer and the horn. The higher the ultrasonic frequency, the more beautiful and precise the welding effect is, but the ultrasonic power of the ultrasonic machine is also smaller.

Specially used for anti-theft button welding, plastic shell and plastic box welding, also used in mobile phone accessories welding, mobile phone shell welding, battery shell, U disk welding, SD card welding, CF card, USB connector welding, Bluetooth welding, mobile phone accessories, etc. Welding precision welding, PP folders, thermos cups, powder boxes, transformers, chargers, rectifiers, plugs, car lights, medical products, transparent cup bottoms, transparent cup handles, plastic toys, electronic boxes, hardware screws connected to plastic posts , mobile phone battery shell, car battery, charger, toys are mainly suitable for: PP material, acrylic, ABS, PC, POM, GS and other difficult welding materials.
