What is Ultrasonic Cleaning?
- Ultrasonic cleaning is a type of cleaning process which uses cavitation induced by alternating compression and rarefaction cycles at ultrasonic frequencies.
- Cavitation removes contaminants on the surface of the part by imparting vibrations through implosions or oscillations of tiny cavities or voids.
- An ultrasonic transducer converts a form of energy, usually electrical or mechanical, into an ultrasonic vibration. The two main types of ultrasonic transducers used for cleaning are piezoelectric and magnetostrictive.
- The ultrasonic generator is the main component of an ultrasonic cleaner which receives power and converts it into a suitable form for energizing the transducer at the desired frequency.
- Other parts of an ultrasonic cleaning machine are the tank, basket, and electrical heaters.
- Several factors can affect cleaning efficiency. These are chemical solution properties, bath temperature, solution chemistry, dissolved gases, frequency, and power.
- There are three main types of ultrasonic cleaning machine according to construction. These are single-tank, multiple-tank, and immersible ultrasonic cleaners.
