Sandblasting

Sandblasting uses compressed air to create a high-speed stream that propels abrasive materials (such as copper ore sand, quartz sand, diamond sand, iron sand, and Hainan sand) onto the surface of the metal that needs to be treated. This causes changes in the outer surface or shape of the metal's surface.

Due to the impact and cutting action of the abrasive material, the surface of the metal obtains a certain degree of cleanliness and different levels of roughness, thereby improving the mechanical properties of the metal's surface.

As a result, the fatigue resistance of the metal is enhanced, the adhesion between the metal and the coating is increased, and the durability of the coating is prolonged.
