Ultrasonic cleaning works through high-frequency sound waves transmitted through liquid to scrub clean the surface of immersed parts. The high-frequency sound waves, typically 40 kHz, agitate the liquid solution of water or solvent.
Ultrasonic energy causes the rapid formation and collapse of small bubbles in the liquid; known as cavitation. A huge burst of energy creates bubbles that quickly increase in size until they burst against the surface of the item.
Ultrasonic cleaning is suitable for cleaning a wide variety of materials. It is especially useful for removing tightly-adhered contaminants from intricate items with blind holes, cracks and recesses. Examples of contaminants removed through ultrasonic cleaning include dust, dirt, oil, grease, pigments, flux agents, fingerprints and polishing compound.
At CDSA we use the ultrasonic cleaner often as part of our injector testing and pre common rail injector and pump rebuilds. This is not however limited to just cleaning diesel injectors and diesel fuel pumps. Due to the majority of parts we clean and the strength of the chemicals we use, it is recommended to clean steel products only with this service. If you have other material types that need cleaning it might be worth looking at our Wet Blasting Service.
