Frequency Auto Tuning 20KHz Ultrasonic Welding Generator for Plastic Welding
20KHz 2500W PLC Control Auto Tuning Ultrasonic Generator /Power Supply for Mask Welding
Ultrasonic technologies are not only quick and efficient but also extremely eco-friendly for processing thermoplastics, films, and fabrics. Ultrasonic in the lower frequency range of 15 kHz to 40 kHz has industrial applications for plastics processing. The ultrasonic frequency is produced by a generator. The generator converts mains voltage into high-frequency high voltage and transfers this to the welding stack, which is made up of the converter, the booster (amplitude transformation unit), and the sonotrode (welding tool).
The principle of the technology is based on the generation of internal heat (molecular friction) by ultrasound and the boundary friction in the join or separation zones of thermoplastics. The converter converts the incoming voltage by electrostriction into mechanical oscillations of the same frequency and conducts them via the booster and sonotrode to the workpiece.
Oscillation absorption, accompanied by the application of pressure and the vertical introduction of mechanical oscillations, creates interface and molecular friction in the joining or separation zone. The result is local heating of the workpiece material in the joining zone. This plasticizing process makes it possible for one or more workpieces to be welded, cut, punched, riveted, or embossed, either continuously or in cycles.
