1500W ultrasonic plastic shell welding machine work principle
Ultrasonic plastic welding machine is the generator produces 20 KHZ (15 KHZ or 40 KHZ) of high pressure, high frequency signal, through the transducer system, the signal conversion for high frequency mechanical vibration, pressure in plastic welding products workpiece, through the workpiece surface and inner friction between the molecules and to raise the temperature of outlet, when the temperature to the melting point of workpiece itself, make workpiece interface rapidly melting, and then fill in the gap between interface, when vibration stop, workpiece at the same time under the pressure of certain cooling setting, achieve perfect welding. Especially suitable for PP, PE, PS, ABS, AMMA and plastic material products.
