Cleaning sound waves

Very high levels of cleaning can be attained using ultrasound cleaning procedures. The cleaning sound waves are employed, for example, in precision mechanics, for electrical and electronic components and prior to further electroplating treatment.

The parts to be cleaned are exposed to ultrasonic waves in a tuned cleaning medium where the oscillation generator can be located on the side wall or base of the cleaning bath. The cleaning effect of the ultrasonic waves is based on the cavitation principle. In the ultrasonically irradiated fluid oscillations cause the formation of minute hollow spaces that collapse again immediately. This produces powerful flows and turbulence which practically "blast off"? the contaminant particles from the goods to be cleaned. For the effectiveness of cleaning the following applies: the lower the frequency, the larger is the cavitation bubble and the greater is the energy released.
