Welding principle

Ultrasonic plastic welding principle is 20 KHZ (or 15 KHZ) generated by the generator of high voltage, high frequency signal, can by changing the system, the signal is converted to high-frequency mechanical vibration, and on the plastic workpiece, through the workpiece surface and the friction and make the transfer to the interface between the molecules of temperature, when the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melting, and then fill in the space between the interface, when the shaking stops, workpiece cooling under certain pressure setting at the same time, a high quality welding. The new 15KHZ ultrasonic plastic welding machine has unique effect on soft PE and PP materials, as well as plastic welders with large diameter and long length. It can meet the needs of various products and contribute to the production efficiency and product grade of users.
