Ultrasonic cleaning makes a solid contribution into the production and manufacturing processes innovation, making the conventional methods obsolete. The article gathers the most frequently asked questions on the technology according to Hilsonic, one of the leading UK ultrasonic cleaner manufacturers. Everything you should know on how to start with the technology is gathered under one roof.
So how it works?
The method implies introducing power into the tank containing the cleaning solution. This energy causes the formation of zillions of small bubbles in the solution that emerge and collapse, this phenomenon is called cavitation. Cavitation leads to a very gentle but totally effective cleaning effect on the surface, which reduces the pollutant.
Why ultrasound method?
Ultrasonic cleaning is the quickest and, perhaps, the most cost-effective precision cleaning method that can deal with the parts of the most complicated shapes. Manual cleaning or spray washing demonstrate poor efficiency when it comes to blind holes, inner tubes or hard-slots, but these tasks are pose no problems when it comes to ultrasonic cleaning.
Depending on the application, the best standards of cleaning can also provide big profits by significantly improving the output cleaning quality and reducing operational expenses.
Shall I choose ultrasound or spray washing?
Water spray washing is an excellent technique designed for a wide variety of applications. Armed with automated mechanisms and conveyor multistage systems (including washing and drying sections, for example) the company can press for a rapid increase in capacity and quality of cleanliness. In certain cases, the heavy dirt better shot blasting sink, which is caused by a strong impingement of the jet of cleaning solution, supplied under pressure, with the surface.
In other cases spray washing and ultrasonic cleaning can achieve equally high standards of cleanliness and cope with the need of bandwidth, so choices can be made based on the cost or preference.
Nevertheless, in certain types of applications ultrasonic cleaning holds a major advantage over spray washing. Here’s the breakdown of cleaning cases:
- Deep, blind holes or complex configuration
- Tubular parts
- Thin or light nodes, which could be susceptible to damage
- Achieving extremely high standards of cleanliness evaluated in fractions of micron size particles or parts per billion, or PPB, to the level of pollution
To find out which process may be most appropriate for your application, a professional audit is the preferable and the most effective option. We make use of solvents. How can we be sure we are not violating the environment protection rules?
The latest generation of cleaners by the leading manufacturers such as Hilsonic are designed to use the new low toxicity solvents with zero ODP (ozone damage potential). You can take advantage of Microsolve Co-solvent and Mono-solvent line-up that guarantee extremely effective solvent exposure.
I use trichlorethylene, but I’m not sure how long I can continue to do so legally. Can you assist?
Legislation on emission of solvents is quite complex, but the equipment engineers can advise on specific issues of how emission standards apply to your company. To do this, you must provide details of how much solvents you use, as well as share more details on technological process.
