The sand blasting process flow of sand blasting includes pretreatment stage and sand blasting process stage:

Pretreatment stage of sand blasting process: it refers to the treatment that should be carried out on the surface of the workpiece before spraying and plating protective layer.

The pretreatment quality of sand blasting process affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. Dalian assembly line sand blasting processing factory

If the pretreatment is not done well, the corrosion will continue to spread under the coating, causing the coating to fall off in pieces. After careful cleaning of the surface and generally simple cleaning of the workpiece, compared with the coating by exposure method, the service life can be 4-5 times different.

Sand blasting process stage: it uses compressed air as power to form a high-speed jet beam, and sprays spraying materials (such as RZG garnet sand and natural emery) to the surface of the workpiece to be treated at high speed, so as to change the appearance of the outer surface of the workpiece. Due to the impact and cutting effect of abrasive on the workpiece surface, the workpiece surface can obtain certain cleanliness and different roughness, and the mechanical properties of the workpiece surface can be improved.
