The last process of zinc alloy die casting is to conduct surface treatment to make the zinc alloy die casting look more beautiful.

Sand blasting is a kind of high-speed spray beam, which is driven by compressed air in the fine die casting plant. It can spray the material to the surface of the workpiece to be treated at high speed, and change the appearance or shape of the workpiece. Due to the impact and cutting effect of abrasive on the surface of the workpiece, the surface of the workpiece gets a certain degree of cleanliness and different roughness, which improves the mechanical properties of the surface of the workpiece. Therefore, it improves the fatigue resistance of the workpiece, increases the adhesion between it and the coating, prolongs the durability of the coating, and is also conducive to the smooth decoration of the coating.

Common spray materials include copper ore, quartz sand, emery, iron sand, sea sand and other options. After sand blasting, the surface of zinc alloy die-casting will have a layer of sand like effect, increasing the sense of hierarchy, making the zinc alloy die-casting look very high-grade.
