The through-type shot blasting machine is a kind of equipment widely used for surface cleaning and processing, suitable for many different types of workpieces and materials. Its working principle is to use the high-speed rotating shot blasting wheel to project the shot blasting medium such as steel shot at high speed onto the surface of the workpiece, so as to achieve the purpose of cleaning, rust removal, oxide scale removal, welding slag removal, surface strengthening, etc. The through-type shot blasting machine is particularly suitable for mass production and continuous operation due to its automatic characteristics. The following are the types of materials that the through-type shot blasting machine is suitable for processing:

1. Metal materials
Cast iron: The through-type shot blasting machine is widely used for surface cleaning of cast iron parts, especially sand mold residues, oxide scales and casting defects on castings. After the cast iron parts are shot blasted, the surface can be evenly cleaned and the surface residues can be removed.
Steel: Steel is one of the common materials processed by the through-type shot blasting machine, and is widely used for cleaning steel plates, steel structures, automotive parts, etc. The shot blasting machine can remove rust, oxide scales and coatings on the surface of steel, making the surface smoother and suitable for subsequent processing (such as painting, welding, etc.). Stainless steel: The through-type shot blasting machine is also suitable for cleaning the surface of stainless steel, especially removing the oxide layer, welding residue and surface dirt, and enhancing the surface finish of stainless steel.

2. Aluminum alloy
Aluminum alloy materials are usually used in industries such as automobiles, aviation, machinery and electronics. The surface of aluminum alloy is prone to form an oxide layer. The through-type shot blasting machine can remove the oxide layer, rust and dirt, making the surface smoother and providing a better foundation for subsequent painting and processing. The light weight and high strength of aluminum alloy make it widely used in aerospace and automobile manufacturing.

3. Copper alloys and other non-ferrous metals
Copper alloys (such as brass, copper, etc.) and other non-ferrous metals (such as zinc alloy, magnesium alloy, etc.) also need surface cleaning in some areas. The through-type shot blasting machine can remove oxides and dirt on the surface of these metals, ensure the surface quality of the material, and increase the accuracy of its subsequent processing.

4. Cast aluminum parts
During the casting process, cast aluminum parts usually have residual casting sand, oxides and surface defects. The use of a through-type shot blasting machine can effectively remove these impurities on the surface of cast aluminum parts, ensure the surface of cast aluminum parts is flat, and provide an ideal surface state for subsequent painting, heating treatment or welding.

5. Building materials
Concrete components: The through-type shot blasting machine is suitable for cleaning the surface of concrete components, especially removing cement slurry, dirt and impurities in cracks on the surface. The concrete surface after shot blasting is not only smoother, but also helps to enhance its adhesion, which is convenient for subsequent construction (such as painting, tiling, etc.).
Masonry materials: For some masonry materials for construction, especially imitation stone permeable bricks, shot blasting machines can remove surface impurities and enhance their weathering resistance.

6. Castings
The surface of castings often has impurities such as casting sand, sand mold residues, oxide scale and pores. The through-type shot blasting machine cleans the surface of the casting by projecting media, removes these unnecessary impurities, and can generate a compressive stress layer on the surface of the workpiece, thereby enhancing its fatigue resistance.

7. Auto parts
Various auto parts, especially body structures, engine housings, brake discs, wheels, etc., usually need to remove rust, dirt and oxide scale on the surface. The through-type shot blasting machine can clean the surface of these parts and improve the quality of subsequent painting or welding.

8. Mechanical parts
Gears: Through-type shot blasting machines are often used to clean mechanical parts, especially gears, bearings, shafts, casting machine parts, etc., to remove rust, impurities and burrs on their surfaces, and improve the processing accuracy and service life of parts.
Fasteners and connectors: including nuts, bolts, pins, etc. These small workpieces are often contaminated by processing residues during the manufacturing process. Shot blasting machines can clean these impurities and prepare for further processing.

9. Electrical equipment and tools
The surfaces of electrical equipment (such as distribution boxes, terminal blocks, etc.) and tools (such as hand tools, machine tools, etc.) are often contaminated during manufacturing and use. The through-type shot blasting machine can remove rust, oxides, etc. on the surface, thereby improving its surface quality and avoiding the impact of corrosion on electrical equipment and tools.

10. Aerospace parts
Some parts in the aerospace field need to be carefully cleaned, especially some high temperature and corrosion resistant materials, such as titanium alloys, aluminum alloys, etc. The through-type shot blasting machine can effectively remove the surface oxide layer and impurities, and enhance the corrosion resistance of the material.

11. Welded structural parts
During the welding process, impurities such as welding residues and oxide scales will adhere to the welding parts, affecting the strength and appearance of the structure. The through-type shot blasting machine can clean the residues, oxide scales, etc. in the welding parts, and improve the quality and strength of the welded structural parts.

Summary:
The through-type shot blasting machine is suitable for the surface cleaning of various metals, aluminum alloys, stainless steel, castings, concrete, building materials, etc., and can effectively remove surface dirt, oxide layers, rust, casting residues and welding residues, and improve the surface quality of the workpiece. Due to its automation characteristics, it is widely used in casting, machinery manufacturing, automobiles, construction, aerospace and other industries.
