Shot-blasting

Description of the technology

Shot-blasting is the process of cleaning or altering the properties of the surface layer of metal parts by using a jet of highly abrasive substances. The abrasive jet is generated by compressed air or by the centripetal force of a turbine, sometimes called a blast wheel.

In order to carry out the process of shot-blasting, loose abrasive material is used: cast steel shot, alumina, crushed glass and garnet.
