28Khz Ultrasonic Spot Welding Machine

28Khz Ultrasonic Spot Welding Machine

Ultrasonic welding principle of spot welding machine is powered 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 surface and inner friction between the molecules and make the transfer to the interface 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 vibration stops, the workpiece is cooled and shaped at a certain pressure to achieve perfect welding.
