Principles: 
The ultrasonic generator converts high-frequency energy will be transferred to mechanical motion of same frequency through ultrasonic transducer, and then the mechanical motion can be transferred to the welding horn by amplitude modulator, which can adjust the amplitude. The welding horn will pass the absorbed heat to the junction of workpieces for welding. In this particular zone, vibration energy can be converted into heat through friction. Ultrasonic can not only be used to weld hard thermoplastic but also to process the textile and thin-film.
Features:
Pll Auto Tuning
The Pll Auto Tuning technology synchronize the frequency change of horn and the AMP output. The synchronization expand the auto tuning range, simplify the fabrication of the welding horn. The AMP would output the perfect vibration no matter how the temperature rises of the welding horn. Hat would also be able to reduce the welding failure rate. Auto tuning range: 15Khz to 350Hz, 20Khz to 700Hz., 40Khz to 800Hz.
Voltage Feed back
Keep the steady output of voltage and amplitude without AVR system. Input voltage variation is allowed between 180V to 240V. This feedback control could guarantee the welding stability.
Overload protect
The upper and lower specification limits of electric current and voltage can be measured, and th e output can be cut out in case there is problem.
Soft start protect
Effective soft start protect could remove the harm to the horn at the very beginning of vibration, and eliminate the malfunction at the ultrasonic vibration. (Tunable range: 10mses~200mses)
Multi-welder cylinder synchronization
Air pressure inspection and air cylinder moving speed adjustment, these two function could guarantee the synchronization of the cylinders movement when multiple welders in needed.
