The lower the ultrasonic frequency, the easier it is to generate cavitation in the liquid. This cavitation produces greater force and a stronger effect, making it suitable for the rough cleaning, heavy-soil cleaning, and initial cleaning of workpieces. In contrast, higher frequencies result in more directional ultrasonic waves, which are ideal for cleaning delicate items. Therefore, the common frequencies of ultrasonic cleaners are 28 kHz and 40 kHz.

Advantages of Ultrasonic Cleaning

Compared with many other cleaning methods, ultrasonic cleaners offer significant advantages. Particularly in specialized and large-scale manufacturing enterprises, ultrasonic cleaners have gradually replaced traditional processes such as immersion cleaning, scrubbing, pressure rinsing, vibration cleaning, and steam cleaning.

The high efficiency and high cleanliness of ultrasonic cleaners stem from the penetrability and cavitation impact effect generated when sound waves propagate in a medium. This makes it easy to clean parts with complex shapes, internal cavities, and fine holes thoroughly. For common processes like oil removal, rust prevention, and phosphating, ultrasonic cleaning can be completed in just two to three minutes under ultrasonic action-its speed is several times, or even dozens of times, faster than that of traditional methods.

In many scenarios where high requirements are placed on product surface quality and production efficiency, ultrasonic cleaning demonstrates results that are difficult to achieve or irreplaceable with other treatment methods. Its advantages can be summarized as follows:

Excellent cleaning results, with high cleanliness and consistent cleanliness across all workpieces.

Fast cleaning speed, which improves production efficiency.

No need for manual contact with the cleaning solution, ensuring safety and reliability.

Capable of thoroughly cleaning deep holes, narrow gaps, and hidden areas of workpieces.

Saves solvents, thermal energy, workplace space, and labor costs.
