 Casting cleaning, removal of molding sand and oxide scale. After the casting is demolded, the sand, binder or oxide layer remaining on the surface can be quickly removed by shot blasting. And cleaning burrs and residual parts after cutting.
 Surface strengthening (shot peening strengthening). Improve the fatigue life of parts, enhance the resistance to stress corrosion, and prevent fatigue cracks.
 Pre-treatment of casting coating/plating. Increase surface roughness (Ra value) and improve the adhesion of paint, electroplating or thermal spraying.
 Weld and defect repair. Clean the weld area to facilitate the detection of cracks or pores; remove surface impurities before repair.
 Eliminate residual stress in castings and reduce the risk of deformation in subsequent processing.
