Ultrasonic cleaning has become standard in the industry. The cleaning is realized by means of high-frequency sound waves. One speaks of ultrasound when the sound is no longer acoustically perceptible to humans. The frequencies here are above 18 kHz.
The vibrations generated by this sound in a water-like liquid cause bubbles to form on the surface to be cleaned. The process by which mechanical sound waves create compression and decompression phases is called cavitation. During the decompression phase, many small cavities are created in the liquid, which implode during the compression phase. The resulting pressure thus removes minute particles from the hard surfaces.
Due to its properties, ultrasonic cleaning can be used for a wide range of soiling. The cleaning success is almost unsurpassed.
