Ultrasonic and/or spray cleaning, our cleaning and surface treatment systems offer you an innovative, state-of-the-art service.

Spraying

This cleaning process, used in a detergent environment, is an activator of the mechanical action of cleaning, using static or rotary nozzles. This mechanical effect is therefore essentially directional, and is nevertheless suitable for parts of simple geometry. Depending on the type of equipment used, sprays may be used at low temperatures or vacuums.

Ultrasonic

This cleaning process, used in a detergent medium, as in a solvent medium, is an activator of the mechanical action of cleaning, by the implementation of the physical phenomenon of cavitation of a liquid. The principle of operation of ultrasonics, is to transform a low frequency electric current 220V / 50 Hz (created by the ultrasonic generator), into a vibration, high frequency, transmitted to the cleaning liquid, thus generating the formation of microbubbles charged with energy, which during their implosion, release an amount of energy equivalent to mechanical brushing. The cavitation of the liquid is homogeneous, at all points of the liquid, the mechanical effect is therefore multidirectional, and is therefore suitable for all kinds of geometries, from the simplest to the most elaborate. The ultrasonic cleaning process can be used at atmospheric pressure or under vacuum, allowing total propagation, including inside blind holes or cavities.

Detergents

These detergent products are used in low concentrations, in baths of hard, osmosis or demineralized water, in addition to a mechanical action, in order to solubilize the pollution to be eliminated on the surface of the parts to be treated. These products may be alkaline or acidic, depending on the pollutants to be removed, incorporating surfactants to promote rinsing or anti-corrosion agents, depending on the sensitivity of the metals to be treated. The use of detergents will allow the use of the terms cleaning or surface preparation. A wide range of products is available, allowing us to develop a cleaning process adapted to any type of part, no matter the constituent material(s). All detergents are generally used, at a temperature ranging from 45°C to 75°C, since temperature is also an activator of solubilizing power.

Solvents

The products of the A3 range (solvents having a flash point between 55 °C and 100°C) are divided into two main ranges: Hydrocarbons (petroleum-derived products) Modified alcohols (synthetic products). These products with neutral pH can be used, under vacuum, in the vapor phase as well as in dip process. Their main advantage lies in their stability and the fact that they can be distilled continuously. The use is therefore simplified, operating costs and consumption are very low. They also have a very important oil absorption power, being mainly intended for the degreasing of surfaces. Hydrocarbons will allow, beyond degreasing, to leave a temporary protective film on the surface of the treated parts. As a result, the surface tension value will not exceed 38 mN/m. On the other hand, the modified alcohols not leave film on the surface of the parts and will allow a surface treatment after the degreasing operation. The surface tension value can then, depending on the material and the surface condition, reach values between 42 and 44 mN/m.
