Product Description
High-Power 20kHz Ultrasonic Welding Machine for Battery Tab & Foil Welding
Working Principle
The transducer converts the high-power ultrasonic frequency oscillating signal generated by the ultrasonic generator into mechanical energy of the corresponding frequency. This energy is applied to the interface of the metal sheets to be welded. At this interface, heat is instantly generated, causing the particles in the metal lattice to activate. As a result, the molecules at the joining interface permeate into each other and form a solid weld.
