The principle of ultrasonic welding by the ultrasonic digital generator 50/60 Hz current is converted into 15,20,30 or 40 kHz energy, even reach 70khz. The high frequency electrical energy is converted by the transducer is again converted into a mechanical movement of the same frequency, followed by the mechanical motion transmitted to the weld head through a set can change the amplitude modulator means. The welding head will be received by the vibration energy transmitted to the engaging portion of the workpiece to be welded, in the region, the vibration energy is by friction by conversion into heat, the plastic melts. Ultrasonic can not only be used to weld the hard thermoplastic fabrics and films can also be processed.
Ultrasonic generator main function is to generate high power and high frequency alternating current, drive the ultrasonic transducer.
Ultrasonic generator is applied to all kinds of ultrasonic equipment, mainly with ultrasonic welding, ultrasonic cutting, ultrasonic chemical sonochemistry .
