The principle of ultrasonic welding by ultrasonic digital general 50/60 Hz current is converted into 15,20,30 or 40 kHz energy, even reach 70khz. The high frequency electrial energy is converted by the transducer is again converted into a mechanical movement of the same frequency, followed by mechanical motion transmitted to the weld head through a set can change the amplitude modulator means. The welding head will be received by vibration energy transmitted to the engaging portion of the workpiece to welded, in the region, the vibration energy is by friction energy is 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 is applied to all kinds of ultrasonic equiment, mainly with ultrasonic welding, ultrasonic cutting, ultrasonic chemical equipment and ultrasonic welding equipment such as non-women fabric.
