Ultrasonic cleaning achieves its cleaning purpose by leveraging the cavitation effect of ultrasonic waves in liquids, which separates, emulsifies, and strips away dirt layers. The so-called cavitation effect is a dynamic process of bubble formation, growth, and collapse. The entire process lasts an extremely short time (on the microsecond scale), yet it can release tremendous energy in an instant while creating a highly unique physical environment.
When ultrasonic waves act on a liquid, a large number of micro-bubbles are generated. These bubbles grow rapidly and then collapse abruptly in the liquid, producing shock waves upon collapse. This entire series of dynamic processes—including expansion, collapse, and oscillation—is called cavitation.
Simply put, ultrasonic waves are converted into high-frequency mechanical vibrations by transducers, which then induce the cavitation effect to realize thorough cleaning.
