The difference between shot blasting and sand blasting is briefly introduced

Although there is only a word difference between shot blasting and sand blasting, both of them use high-pressure air or compressed air as the power to blow out the workpiece at high speed and hit the surface of the workpiece to achieve the cleaning effect, but the editor of dahong new material reminds us that they choose different media, the effect is also different.Here is a brief introduction of the differences between them:

After sandblasting, the workpiece surface dirt is removed, the workpiece surface is slightly damaged, and the surface area is greatly increased, thus increasing the bonding strength of the workpiece and the coating. MIM experts found that the surface of the workpiece after sandblasting is metallic, but because the surface is rough, the light is refracted, so there is no metallic luster, it is dark surface.

After shot peening, the surface dirt of workpiece is removed, the surface of workpiece is slightly damaged and the surface area is increased. Since the workpiece surface is not damaged during the processing, the extra energy generated during the processing will lead to the surface strengthening of the workpiece matrix. The surface of the workpiece treated with shot peening is also the same as that of metal. However, as the surface is a spherical surface, part of the light is refracted, so the workpiece is processed as a matte effect.

Above is the distinction that gush shot and gush arenaceous, did not know everybody? More about MIM technology and MIM materials, welcome to consult the professional team of MIM injection molding for new materials of guangdong da-hong metal powder.
