Spray cleaning

Spray cleaning works by spraying liquid (water, detergent solution, solvents) under pressure onto the parts to be treated. This process is effective for removing surface dirt.

Direct mechanical action

There are several types of spray cleaning.

Firstly, wash tunnels, for example, offer high throughput rates and are suitable for large numbers of homogeneous parts. The equipment is bulky and requires high-pressure pumps. Their implementation allows for very limited flexibility.

In contrast, “carousel” machines offer a simple and space-saving solution for cleaning smaller or larger parts in small quantities. These processes are ideal for mechanical maintenance in the railway or aerospace industries, to remove dust, grease, and other contaminants.

In addition, chip spin dryers can also be classified as spray machines. A basket in which chips from machining are sprayed with detergent, while the basket rotates at several hundred revolutions per minute to remove as much oil as possible from the metal mass. This application is particularly useful for precious metal machinists.

Finally, departicleing prevents cleaned parts from remaining in contact with the contaminated cleaning solution, ensuring a very high level of cleanliness. The orientation and power of the jets, combined with the addition of detergent, provide a combination that is particularly suitable for removing fine particles from the surface of parts whose geometry does not present any retention areas or gaps. In this configuration, the cleaning solution is not usually recycled, resulting in higher detergent consumption.
