Is it better to use sandblasting machine or shot blasting machine for surface treatment of aluminum products?

      Surface treatment of aluminum products usually, after the processing of aluminum products, there is no smooth and perfect surface, and the oxidation speed is fast. Because the grade of the product needs to be improved, the appearance must be enhanced, so the corresponding surface treatment of the product can achieve the desired effect. Because the aluminum product itself is soft and has poor wear resistance, the sandblasting machine uses compressed air as the power and uses a pneumatic source high-speed jet beam to spray sand and abrasive onto the surface of the workpiece, so that the surface of the workpiece is deformed and then cleaned. The degree and roughness, mechanical properties are changed, which improves the fatigue resistance of the workpiece; it is also more conducive to the leveling and decoration of the coating, and it can also remove the oxide scale on the surface of the aluminum product.

　　The use of chemical pickling is not only highly corrosive, but also environmentally friendly, and the environmental damage is high.

      Although shot blasting equipment can also achieve this effect, because the material handled by the shot blasting equipment requires high hardness and is not afraid of collisions, aluminum is a material that is easier to wear in the metallic grade, and the pressure resistance level is low. This type of equipment should be selected for surface treatment! The surface treatment of aluminum products is more suitable for sandblasting.
