The ultrasonic plastic welding machine uses an energy conversion system to convert high-frequency electronic energy into high-frequency mechanical vibration, which is transmitted to the plastic body through the welding mold, causing the plastic joint
surface to rapidly rub at a high frequency of 28000 cycles per second until it melts, resulting in a "plastic flow" of material
between the plastic joint surfaces and completing the bonding process in an instant.
