1. Ultrasonic welding machine is the use of ultrasonic generator to convert low current frequency to high frequency AC, then the same frequency of mechanical vibration by ultrasonic transducer.
2. Mechanical vibration transmitted to the ultrasonic welding joints by the amplitude modulator, the vibrational energy welding joints received transfer to the workpiece to be welded joint. In the region, the energy through friction converted into heat energy, to melt the plastic.
3. After vibration stopped, maintain short-term pressure makes the weldment on artifacts in molecular link way solidification as a whole.
