1. Shot blasting and sandblasting are surface treatments, but it is not that only castings are shot.
2. The main function of sand blasting is surface rust removal, descaling, etc., such as heat-treated parts, and the effect and function of shot blasting are more: not only rust removal, but also surface roughness, surface roughness, removal of parts Machining burrs to eliminate internal stress in the part.
3. There are many processes for shot peening, such as: castings, forgings, parts of parts after machining, and parts after heat treatment of parts.
4. Sand blasting is mainly manual operation, while shot blasting is automated and semi-automatic.
5. Steel shots and iron shots used in shot blasting are not really pills in the true sense. Accurately speaking, it is a small steel wire or a small steel stick. It only looks like a meatball after a period of use. The so-called sandblasted sand To put it bluntly, it is just river sand. It is no different from the construction. It is only sieved with sandblasting, with less mud and particle size specifications. Of course, some industries are also different. For example, the shipbuilding industry uses real steel shots for shot blasting and metal ore (not river sand-quartz sand) for sandblasting.
6. Pills and sand Pills are generally spherical and non-angular particles. For example, steel wire cutting pills; sand refers to angular sand grains, such as brown corundum, white corundum, river sand and so on.
7. Spraying and throwing spray is the use of compressed air as the power to spray sand or pellets onto the surface of the material to achieve a clear and a certain roughness. The shot blasting machine manufacturer is a method of centrifugal force generated when the pellets are rotated at a high speed, impacting the surface of the material to achieve removal and a certain roughness.
