Ultrasonic Cleaning Industry Information
Ultrasonic cleaner manufacturers offer a variety of
specialized cleaning machines that are used in both industrial and commercial
settings to clean parts and products. Ultrasonic cleaners utilize ultrasonic
sound frequencies that are above the range of human hearing. The ultrasonic
sound waves are provided by transducers, which convert electricity into
intense ultrasonic frequencies. Commercial uses for ultrasonic cleaning
equipment include golf club cleaners, window blind cleaners and jewelry
cleaners. Industrial uses include pre- and post-production cleaning,
automotive parts cleaning and critical and precision cleaning. Ultrasonic
cleaner manufacturers make products that clean, rinse and dry batches
of parts.
Cleaning depends on cavitation, which is the rapid formation and violent
collapse of minute bubbles or cavities in a cleaning fluid. This process
results in agitation, due to the numerous small and intense imploding
bubbles, which produces an effective scrubbing of all surfaces, exposed
and hidden, of the submerged parts. The frequency level of the sound
waves affects the size and amount of cavitation. Adjusting the frequency
according to the parts being cleaned ensures that the energy from the
cavitation reaches and penetrates all areas of the part, no matter how
complex. The cleaning process involves immersing a part into an agitated
fluid (usually pure water, solvent or vapor) for a short period of time.
The parts are then rinsed and dried, completing the process.
Ultrasonic cleaners began by relying heavily on chemical solvents to
clean products. However, regulations and attitudes have since changed,
requiring the ultrasonic cleaner manufacturers to phase out hazardous
chemicals that are potentially harmful to the environment and individual
health. The problem is many contaminants, greases and tightly bonded
soils cannot be removed with just water or non-hazardous solvents and
chemicals. Now, aqueous cleaning techniques combined with ultrasonic
cleaning technology are able to remove most challenging soils and bonded
oils in a more environmentally-safe and efficient way.
Ultrasonic cleaners present distinct advantages over other techniques.
The three most important benefits are accuracy, consistency and speed.
Certain factors are important in deciding what ultrasonic cleaner is
right for a particular application. These factors determine the size
and type of the machine, as well as the solvents involved. The intricacy
of the parts, including size, shape and weight, are important for determining
the size and type of equipment. The amount and type of soil on the parts
determines the cleaning medium. The rate of cleaning is also important,
such as whether parts will be cleaned in batches, on a continual basis
or intermittently. Another important factor to consider is the required
standard of cleanliness.
