sandblasting

The terms sandblasting and shot peening in Italy are sometimes used interchangeably but in fact they describe two very distinct procedures for surface treatment and finishing in different industrial fields.

What is sandblasting?

Sandblasting is the procedure that allows you to remove and eliminate, with a stream of abrasive and air launched at high speed and at very high pressure, impurities and corrosive slags: paints, rust, oxides, sand and calamine. In this way the surface can be prepared in order to create the best adhesion between the surface and the coating that will be applied or reapplied on the it.

For the sandblasting process, various types of abrasive material are used depending on the result to be obtained in terms of cleanliness and roughness of the surface. Mineral abrasives

The sandblasting process is a mechanical technique for the controlled cleaning of a surface, usually metallic. It is made by erosion thanks to the abrasion generated by propelling metal shots or grit with compressed air lances.

Another method uses wheel blasting machines. The sandblasting process, in addition to allowing the surface of a metal product to be cleaned from residues and corrosive scales, can also be used to obtain a particular surface roughness for subsequent coating or painting processes. In the case of shot-peening, on the other hand, it’s used to add strength and reduce the stress profile of special components.
