The working principle is that the generator generates 20KHz or 15KHz high voltage, high frequency signal, through the ring energy system, the signal is converted into high frequency mechanical vibration, and added to the plastic products workpiece, through the workpiece surface and the friction between molecules and the temperature transferred to the interface increases, when the temperature reaches the melting point of the workpiece itself, the workpiece interface quickly melts

4.High thermal conductivity
