Ultrasonic Cleaning Process
In recent years, improved equipment designs, combined with the advent of advanced, non ozone-depleting solvents, have spurred a resurgence in the use of vapour degreasing cleaning systems. In addition, the rise of cell manufacturing, in which workers are arranged in semi-autonomous teams rather than long production lines, has made the use of low-volume/small-footprint vapour degreasers a more attractive option than large centrally-located aqueous cleaning systems.
In many applications requiring high purity and low contaminant levels on finished parts, such as electronic components, aerospace materials and medical devices, solvent systems can offer a number of important cost and performance advantages over aqueous systems.
Typical Solvent Cleaning Stages
- Part is lowered into immersion sump with ultrasonic agitation and cleaned for around 5 minutes.
- Part is raised into vapour zone, and held for 1 minute.
- Part moves to freeboard zone, allowing solvent to evaporate and return to sump.
- Part emerges clean and completely dry.
Total elapsed time to finished part: 7 Minutes
Typical Aqueous Cleaning Stages
- Part is immersed in hot cleaning solution agitated by ultrasonics for 5 minutes. Depending on soil may require the addition of rust inhibitors.
- Part is immersed in first rinse tank for 3 minutes.
- Part is immersed in second rinse tank for 3 minutes.
- Part is held in drying chamber to evaporate water for 5 minutes.
Total elapsed time to finished part: 16 Minutes*Times required for cleaning and drying operations vary and depends on a variety of factors. General range for solvent cleaning is 1-7 minutes, while aqueous cleaning can take anywhere from 7 minutes to an hour or more.
