Ultrasonic cleaning is that the transducer converts the electric energy provided by the ultrasonic power supply into ultrasonic frequency mechanical vibration, and radiates sound waves to the cleaning liquid contained in the tank through the cleaning tank wall, when the sound pressure reaches a certain value, the micro-bubble (cavitation core) in the liquid vibrates under the action of sound field. When the sound pressure reaches a certain value, the bubble grows rapidly, then suddenly closes, and a shock wave is produced when the bubble closes, it creates thousands of atmospheres of pressure around it, destroying the insoluble dirt, which disperses it in the cleaning fluid. Where liquid is immersed and cavitation is generated, it is used for cleaning, not limited by the complex shape of the surface of the parts to be cleaned, such as holes, grooves, slits and deep holes on the surface of precision parts, micro holes can be cleaned, these parts of the general cleaning method can not be cleaned. Ultrasonic cleaning is the best choice to improve the cleaning efficiency.

Ultrasonic cleaners are used to clean many different types of objects, includes jewelry, scientific samples, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, pens, golf clubs, fishing line wheels, shutters, car injectors, musical instruments, gramophone records, industrial machinery parts and electronic equipment. They are used by many jewelry studios, watchmakers, electronics repair shops and science laboratories.
