20Khz Ultrasonic Welding Machine with Touch Screen for Auto Welding 

1. The principle of ultrasonic welding

The ultrasonic generator generates the signal frequency required by the ultrasonic transducer, and then uses the thermoplasticity of the plastic to generate heat at a very high speed between the molecules by using high-frequency friction between the working surfaces. When the heat is sufficient to melt, the ultrasonic wave is stopped. Vibration, at this time the workpiece joint is solidified by melting, complete the processing procedure! The traditional ultrasonic generator is manually frequency-modulated, and HZ-2000 digital ultrasonic generator realizes automatic frequency tracking, real-time power display, and friendly communication of human-machine interface!

The frequencies commonly used for plastic processing are 15 kHz and 20 kHz, of which 20 kHz is outside the human hearing range, so it is called ultrasonic, but 15 kHz is still in the human hearing range.
