Shot Blasting Machine Applications

1. Clean the metal surface.

Shot blasting equipment was first used in the foundry industry to remove sand and scale on the surface of cast steel and iron castings. The high-speed and dense particle beam discharged by the shot blasting machine attacks the rust layer, welding slag, oxide scale and haze on the surface of the original steel material, and the rust layer, welding slag, oxide scale and haze on the surface of the original steel material quickly fall off. It gives a certain surface smoothness and hardness, improves the adhesion between the paint film and the steel, improves the internal quality of the metal and prolongs its service life. Almost all steel castings, gray castings, ductile castings, ductile iron castings, etc. need to be subjected to shot blasting. It is not only the removal of scale and sand on the surface of castings, but also a necessary preparatory process before casting quality inspection. For example, the shell of large gas turbines must be strictly shot blasted before non-destructive testing to ensure the reliability of the test results. In general foundry industry, shot blasting is an indispensable process for detecting surface defects of castings such as subcutaneous pores, slag cavities, sand adhesion, cold freezing, peeling, etc. Surface shot blasting of non-ferrous metal castings such as aluminum alloy and copper alloy, in addition to removing oxide scale and detecting surface defects of castings, mainly aims to remove burrs of castings and obtain a surface quality with decorative value through shot blasting to achieve a comprehensive effect. 2. Strengthening of metal parts

According to the modern theory of metal strength, the main direction of increasing the strength properties of metal is to increase the density of dislocations inside the metal. Practice has shown that shot blasting is the most effective process for increasing the dislocation structure of metals. This is even more important for parts that cannot be strengthened by phase transformation or that require additional strengthening based on strengthening by phase transformation. Molds, gears, machine tools, tractors and other parts require lighter weight, but technical requirements are becoming increasingly stringent. An important technological measure is the use of shot blasting technology with a shot blasting machine to increase the strength and hardness of parts.

3. In the construction industry, in the production of stone, cement brick, decorative aluminum, stainless steel and other industries, surface roughening is used, which should replace the previous processes of high energy consumption, firing and etching.

4. Roughening the surface of aluminum alloy parts, plastic parts, etc. to increase the surface roughness, improve the adhesion of coatings or electroplating, improve the appearance of texture, and sometimes increase the coefficient of surface friction.
