Ultrasonic plastic welding principle is produced by generator 20KHZ (or 15KHZ) of high pressure, high frequency signal, through changing systems, to the signals are converted to high-frequency mechanical vibration, and in plastic products of workpiece, through the surface of workpiece and internal friction between the molecules that interface temperature, when the temperature reaches the workpiece itself the melting point, to make the work quickly melted, and interface, filling the gap between interface, when the vibration stop, workpiece simultaneously under the pressure of certain cooling shapes, then achieve perfect welding.
