Sand blasting treatment is using compressed air to spray to Metal Abrasive to the surface of the workpiece with high speed, so as to improve the appearance quality by clearing the oxide and rust on the surface. Shot blasting treatment is to attack the metal workpiece surface by high speed hard particles, in order to improve the fatigue strength of the metal surface. The two kinds of treatment process tools are different.
The medium of these two methods can be used circularly. The Shot Blasting Machine technology instead of the general cold and hot forming process, process the large thin-walled aluminum parts, not only can avoid the residual tensile stress on the part surface, but also can get the favorable compressive stress on the parts. It should be noted that the service temperature of the parts processed by shot blasting machine is not too high, otherwise the compressive stress will disappear automatically at high temperature, so lost the expected effect. Their use temperature is determined by the material of the parts.
Kaitai Group is China top Sand Blasting Machine Supplier, shot blasting machine manufacturer with high quality with appropriate price.
