An ultrasonic solvent degreaser delivers optimum results when cleaning small objects, especially those with complex shapes. It’s a highly effective process for ensuring that every nook and cranny of a surface is kept clean. Given the size of the investment, it’s essential to consult a specialist in the field when purchasing your cleaning machine.
Ultrasonic degreasing for highly precise cleaning
Ultrasonic cleaning, including solvent degreasing, is performed using a special industrial machine. The process consists in removing all particles that have adhered to the surface, even in the smallest gaps, thanks to the phenomenon of cavitation. The principle is as follows: high sound frequencies (from 20kHz to 170kHz) cause micro-bubbles to form in the liquid in the tank, then these bubbles implode and the liquid seeps into every nook and cranny of the object to be cleaned.
Adding a solvent helps to achieve better results, as the action of water is limited. What’s more, some solutions promote cavitation, producing a greater number of bubbles for greater precision when washing/degreasing. In addition, it’s best to operate at a temperature of around 50°C for optimum solvent efficiency.
An ultrasonic degreasing machine essentially comprises a tank, transducers and a high-frequency generator. The use of a specific solution is recommended, as each field of application for this type of cleaning has its own specific solvents.
Advantages of ultrasonic degreasing
Ultrasonic degreasing is used in a wide range of sectors: dentistry, optics, laboratories, jewelry, archaeology, etc. The main advantage is the ability to degrease even the smallest surfaces, removing the smallest particles (down to 15 microns). This efficiency makes it possible to clean even the most complex shapes. What’s more, there’s no need to dismantle objects beforehand, even when different materials are involved.
While solvents are often used, chemical reagents are employed in small quantities. Since the operation is carried out in a dedicated tank, with no manual handling of solutions, there is no projection of hazardous substances. The absence of human intervention during the process means that the time spent degreasing is profitable, and labor is saved. Last but not least, it’s a very fast process, taking just a few minutes, twenty at the most. Combined with high-precision cleaning, this processing speed makes the technique highly efficient. Ultrasonic degreasing machines and solvents are therefore indispensable in the industrial field.
How do I know which machine I need?
It’s often very difficult to make the right choice when we don’t have the knowledge of this type of industrial machinery. We advise you to contact the experts in parts cleaning. They’ll help you make the right choice for the parts cleaning machine best suited to your needs and sector. Some manufacturers adapt their machines to your production line, integrating them directly into your manufacturing process.
Other industrial cleaning machines are also available, using different techniques depending on your activities and needs: spray or immersion washing fountains, leach degreasing systems, sandblasting cabins, tribofinishing and drying equipment for surface treatment…
