How Ultrasonics Work

How ultrasonics work

Ultrasonic cleaning is a precision parts cleaning technology that uses high-frequency sound waves to remove dirt and contaminants from parts. Micron-sized bubbles are formed from the alternating pressure waves generated from high-energy transducers. Energy is transferred to and stored within these bubbles. As the bubbles contact the parts to be cleaned, they implode, releasing the stored energy and creating a micro jet, with a kind of scrubbing action that dislodges contaminants from the parts.  Dirt, oils and other dislodged contaminants then settle to the bottom of the tank.

The process of formation and collapse/implosion of these tiny bubbles is called cavitation, and is common to all ultrasonic cleaners. What is unique about the UltraSonic technology is the placement of the transducers on the side of the tank, rather than on the bottom (as virtually all other manufacturers do).

Unlike bottom-mounted transducers, side-mounted transducers provide a consistent cleaning action from top to bottom, with no “blind spots.” To further ensure that all surfaces are cleaned, an agitation table, which holds either the parts or part baskets, oscillates within the tank. This movement guarantees that all surfaces of the components contact the transducer waves. A V-shaped bottom also allows dough, dirt and grime to collect on the bottom without interfering in the transducer’s wave path, and it allows for easy cleaning.
