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.
