Sandblasting is a technological process of removing various impurities from different surfaces with the help of an abrasive and a device or chamber for sandblasting, in order to obtain a certain quality, roughness or desired purity. The process is based on compressed air that creates a pneumatic acceleration of the abrasive and is applied to the blasting surface through appropriate nozzles.
Different abrasives, different blasting nozzles and different air pressure levels are used. With all these parameters it is possible to control the blows on the treated surface.
