Briefly introduce the difference between shot blasting and sand blasting

Although there is only one word difference between shot blasting and sand blasting, both of them use high-pressure air or compressed air as power to blow it out at a high speed and impact the workpiece surface to achieve cleaning effect, but the Zhongwei Precision Editor specially reminds you that they choose different media and have different effects. The following is a brief introduction to the differences between them:

After sand blasting, the dirt on the workpiece surface is removed, the workpiece surface is slightly damaged, and the surface area is greatly increased, thus increasing the bonding strength between the workpiece and the coating/plating. MIM zhongwei precision expert of metal injection molding found that the surface of the workpiece after sand blasting treatment is metallic, but because the surface is rough, the light is refracted off, so there is no metallic luster, and it is a darkened surface.

After shot peening, the dirt on the surface of the workpiece is removed, and the surface of the workpiece is slightly and is not easy to be damaged, so the surface area is increased. Since the workpiece surface is not damaged during the processing, the excess energy generated during the processing will cause the surface strengthening of the workpiece substrate. Zhongwei precisely reminds you that the surface of the workpiece after shot peening is also metallic, but because the surface is spherical and part of the light is refracted, the workpiece is processed into a matte effect.

The above is the difference between shot blasting and sand blasting. Do you know it? For more information about MIM technology and MIM materials, please consult the MIM technology professional team of Zhongwei Precision Metal Powder Injection Molding in Qinhuangdao!
