Compared with other cleaning methods, the ultrasonic cleaning machine shows great advantages. Especially in the specialized and group production enterprises, ultrasonic cleaning machine has gradually replaced the traditional soaking, scrubbing, pressure washing, vibration cleaning and steam cleaning processes. The high efficiency and cleanliness of the ultrasonic cleaner are due to the penetration and cavitation shock wave generated by the sound wave propagating in the medium. Therefore, it is easy to clean the parts with complex shape, inner cavity and hollow. For general degreasing, rust prevention, phosphating and other processes, it can be completed in only two or three minutes under the action of ultrasound. Its speed is several times to dozens of times faster than traditional methods, and its cleanliness can also reach high standards. This is more protruding in many situations requiring higher surface quality and productivity of products. The results show that other methods are difficult to achieve or irreplaceable.
