Ultrasonic welding machine through the ultrasonic generator will Hz current into high-frequency AC power, the energy input ultrasonic transducer to produce the same frequency of mechanical movement. The mechanical movement passes through the amplitude modulation device to the ultrasonic welding head, and the welding head transmits the vibration energy received to the joints of the workpiece to be welded. In this area, energy is converted into heat by friction, melting the plastic.
The transient pressure maintained on the workpiece after the vibration stops causes the two welds to solidify together in the form of molecular linkage. The general welding time is less than 1 seconds, the welding strength can be compared with the body.
