What Exactly Does Precision Cleaning Mean?

The term “precision cleaning” describes a process that requires a clearly defined maximum allowable level of particle, film or impurity contamination on the surfaces to be cleaned. Precision cleaning is usually done with reference to a standard, such as a particle count or film contamination.

Compared to ordinary cleaning wherein a significant amount of impurities on the surface of the parts to be cleaned is removed but doesn't specify how much is left, precision cleaning cleans until the targets for the remaining contamination are reached.

Many industries, including medical, pharmaceutical and aerospace use precision cleaning standards in their manufacturing processes. Coating metal parts, plating components, cleaning tools prior to disinfection and cleaning silicon prior to diffusion, require high standards of cleanliness. It means that an inspection of the part shows that it has been cleaned to confirm any remaining level of contamination is within the permissible tolerances.

Cleaning with chemicals and manual cleaning are some of the methods used for precision cleaning. They may be expensive, time-consuming and labor-intensive. These methods do not guarantee that the parts are thoroughly and precisely cleaned.

Cleaning with ultrasonic cleaners addresses all these drawbacks and offers a complete cleaning solution for precision cleaning needs. Ultrasonic cleaning works by producing high-frequency sound waves at specified power levels in water or in a gentle cleaning solution. The parts to be cleaned are immersed in the cleaning solution and the ultrasonic waves dislodge dirt and contaminants from surfaces. The ultrasonic waves penetrate wherever there is cleaning solution and delivers an even and thorough cleaning action. Ultrasonic cleaning is ideal for parts with intricate shapes, holes, and crevices. Kaijo Shibuya is a leading ultrasonic cleaning manufacturer that offers a complete line of ultrasonic cleaners and components for precision cleaning applications.

How to Select the Best Ultrasonic Generator for Your Cleaning Applications

Among all the components of an ultrasonic cleaning system (generators, transducers, and a cleaning tank), it is the ultrasonic generator that determines its main characteristic of the system. Therefore, choosing the right ultrasonic generator is essential for obtaining the specified performance desired. The generator needs to have the right operating specifications and capabilities required for the cleaning application. In addition, the transducers and tank size have to match the generator as well. If the right generator is not selected, the system may work more slowly than expected or may not clean completely.

 Selecting the power of the ultrasonic generator depends on the size of the parts being cleaned. The parts must fit inside the cleaning tank and be submerged in the cleaning solution. The tank size, in turn, determines how much power is required to fill the tank evenly with ultrasonic waves.

The generator frequency determines the intensity of the ultrasonic cleaning action. A low frequency creates large cavitation bubbles that deliver robust scrubbing and cleaning action (appropriate for cleaning parts made of hard materials). A high frequency, on the other hand, creates smaller cavitation bubbles that deliver gentle cleaning action (appropriate for cleaning more delicate parts). An ultrasonic generator should be selected that produces the corresponding frequency, multiple frequencies or a frequency range that is needed for the specific cleaning application.

 Kaijo’s Quava high power ultrasonic generator, for instance, delivers up to 1200 W power and is configurable to 10 frequencies which range from 26 kHz to 950 kHz. This generator is ideal for cleaning parts ranging from metal engine components encrusted with oil, grease, and deposits to delicate circuit boards or optical components.

The Phenix Hyper ultrasonic cleaning generator provides a standard sweep mode or in a special hyper mode to improve cleaning performance. Hyper mode allows ultrasonic energy produced by the generator to fill the cleaning tank evenly. This provides optimum cleaning for many kinds of parts, even those with complex shapes, quickly and completely. This ultrasonic cleaning generator operates at 78 kHz with 1200 Watts of power and has an auto-tuning function that keeps the frequency adjusted when operating conditions change.
