Ultrasonic cleaning
A basic ultrasonic cleaner is a cleaning device that uses
ultrasound (usually from 20–400 KHZ) and an appropriate cleaning
solution to clean items. The ultrasound can be used with just
water, but use of an ultrasonic soap appropriate for the item to be
cleaned and the soiling enhances the effect. Cleaning normally
lasts between three and six minutes.
Ultrasonic cleaners can be used for a wide variety of applications,
including plastic parts, bearings, bolts, rubber parts, internal
parts, plastic injection molds, transmission parts and final
cleaning all engine parts prior to assembly.
Ultrasonic cleaning can clean contaminants that include dust, dirt,
oil, pigments, rust, grease, algae, fungus, bacteria, lime scale,
polishing compounds, flux agents, fingerprints, soot wax and mold
release agents and biological soil.
The versatility of ultrasonic cleaning machines make them an ideal
choice for the automotive, medical, pharmaceutical, aerospace and
engineering industries, as well as many other industrial
industries.
How ultrasonic cleaning works
Ultrasonic cleaning uses cavitation bubbles induced by
high-frequency pressure (sound) waves to agitate a liquid. The
agitation produces high forces on contaminants adhering to
substrates like metals, plastics, glass, rubber and ceramics. This
action also penetrates blind holes, cracks and recesses. The
intention is to thoroughly remove all traces of contamination
tightly adhering or embedded onto solid surfaces. Water or solvents
can be used, depending on the type of contamination and the part.
