The ultrasonic cleaning tank is similar to a container, containing cleaning solution and the washed parts. In general, the transducer is directly connected (bonded or welded) to the bottom of the cleaning tank, and the cleaning tank is used as an ultrasonic vibration radiation plate. In order to have good corrosion resistance, fatigue resistance, and sound conductivity, cleaning tanks or ultrasonic vibration radiation plates are commonly made of stainless steel.

Ultrasonic cleaning is currently the most effective and indispensable cleaning method in industry. Ultrasonic cleaners are instruments that use the chemical cleaning agent of ultrasonic waves combined with cavitation to clean workpieces. Firstly, the dirt is infiltrated and dissolved by the chemical action of the cleaning agent. Then, the impact force generated by ultrasonic cavitation peels off the dirt layer on the surface of the object, and it is stirred, dispersed, emulsified to prevent the dirt that has already detached from the surface of the object from reattaching to the object.
