Ultrasonic Washing Machine
Product Details:
The Ultrasonic is the science of sound waves. These sound waves form a bombarding effect on material to be cleaned. To extract the effectiveness of ultrasound it requires a medium  such as water or solvent for the waves to propagate.

The object to be cleaned is immersed in the solvent and the ultrasound is passed to the solvent. As the waves pass, the liquid fractures or tears because of the negative pressure. This pressure builds up and finally the violent collapse of the cavitations bubbles result in implosions which causes shock waves to radiate. 
Ultrasonic Cleaners are widely used to clean intricate parts. The ultrasound generator generates High Frequency, which is applied to water. Thus water starts resonating at that frequency. This pulsating water molecules splash on the submerged jobs, which in turn get impounded by this frequency. This action loosens the dirt from cavities.
