Surface cleaning of the shot blasting machine
Shot blasting machine is first used to remove the surface sand and oxide scale of steel castings and iron castings in the foundry industry.

Almost all steel castings(shot blasting machine), gray castings, Ma steel castings and ductile iron castings shall be shot blasted. This is not only to remove the oxide scale and sand sticking on the casting surface, but also an indispensable preparation process before casting quality inspection. For example, strict shot blasting must be carried out for the casing of large gas turbine before NDT, so as to ensure the reliability of flaw detection results. In general casting production, shot blasting is an essential process to find casting surface defects such as subcutaneous pores, slag holes, sand sticking, cold shut, peeling and so on. The surface cleaning of non-ferrous metal castings, such as aluminum alloy and copper alloy, in addition to removing oxide scale and finding surface defects of castings, the main purpose is to remove burrs of die castings by shot blasting and obtain surface quality with decoration significance to obtain comprehensive effects.
