How does ultrasonic welding work?
Each object has its special frequency, by which the object is stable and easy to oscillate. By adding an external force that corresponds to that special frequency, a small force can obtain a large oscillation. This phenomenon is called resonance. The cutting edge is oscillated greatly with the use of resonance. The ultrasonic welding unit is composed of a "transducer" that generates oscillation and an "oscillator" that drives the transducer. Piezoelectric elements are incorporated in the transducer, and by applying an AC voltage aligned with the characteristic frequency of transducer from the oscillator to the piezoelectric element, the entire vibrator including the welding blade is resonated. Transducer comes with feedback-control system which transmits information of frequency or amplitude deviation to oscillator caused by cutting load. The feedback-control system can keep resonance state and amplitude of blade stable and it enable the cutters always to cut materials sharply and cleanly. Ultrasonic vibrates its blade 20,000 - 40,000 times per second (20 - 40 kHz). Because of this movement, the ultrasonic can easily welding resin, rubber, nonwoven fabric and composite materials.
