The principle of ultrasonic plastic welding is that the generator generates 20kHz (or 15KHz) high-voltage and high-frequency signals. Through the energy conversion system, the signals are converted into high-frequency mechanical vibration, which is added to the workpiece of plastic products. Through the surface of the workpiece and the friction between molecules, the temperature transmitted to the interface increases. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly, and then fills the gap between the interfaces. When the vibration stops, At the same time, the workpiece is cooled and shaped under a certain pressure to achieve perfect welding. Ultrasonic welding machine can be divided into automatic welding machine, semi-automatic ultrasonic welding machine and manual welding machine according to the automation level.

15K ultrasonic plastic welding machine can be divided into 2600w, 3200W and 4200W It is suitable for welding large, difficult and complex plastic products
