A through-type shot blasting machine is a device used to clean, remove rust, and strengthen metal surfaces. It is widely used in steel, casting, machinery manufacturing and other industries. It uses a high-speed rotating shot blasting machine to spray abrasives such as steel shots and cast iron shots at high speed on the surface of the workpiece to be processed, thereby achieving surface cleaning, removing oxides, impurities or other contaminants, and even strengthening the surface of the workpiece.
The main functions of a through-type shot blasting machine include:

1. Surface cleaning
Functional description: The core function of a through-type shot blasting machine is to clean dirt, rust, scale, oil and other impurities on the surface of the workpiece. These impurities will affect the surface quality of the workpiece or subsequent processing (such as painting, welding, etc.). Therefore, surface cleaning is a common application of shot blasting machines.
Application examples: Cast steel parts, cast iron parts, metal structural parts, etc., under the action of a through-type shot blasting machine, rust, scale and other impurities attached to the surface can be removed, so that the surface of the workpiece can achieve better cleanliness.

2. Rust removal and descaling
Function description: The through-type shot blasting machine is very suitable for removing rust and scale on the surface of metal workpieces. Especially in the steel industry, an oxide layer often forms on the surface of steel, affecting its subsequent processing or coating. The shot blasting machine removes the oxide by impact, effectively improving the surface quality of the workpiece.
Application example: The surface oxide removal of metal materials such as steel plates, steel pipes, and steel bars provides a better foundation for subsequent spraying, welding and other processes.

3. Strengthening the metal surface
Function description: Shot blasting can not only clean the surface, but also form compressive stress on the surface of the workpiece through high-speed impact, which plays a role in surface strengthening. This function is usually used to improve the wear resistance, fatigue resistance and corrosion resistance of metal parts and extend the service life of the workpiece.
Application example: In the field of casting and machinery manufacturing, castings or mechanical parts can be strengthened by shot blasting to improve their wear resistance and stress corrosion resistance, especially in the automotive, aviation and other industries.

4. Remove sand from the surface of castings
Function description: During the casting process, the metal flows into the mold and cools down, leaving a sand mold. The through-type shot blasting machine can effectively remove the sand and remaining sand core on the surface of the casting to ensure that the surface of the casting is clean and smooth.
Application example: Foundries often use through-type shot blasting machines to clean the residual sand on cast iron and steel castings to ensure the accuracy and appearance of the castings.

5. Surface finishing and polishing
Function description: The abrasive of the through-type shot blasting machine can not only clean the surface under high-speed impact, but also perform a certain polishing treatment on the metal surface, making the surface of the workpiece smoother and flatter.
Application example: In some industries with high requirements for appearance and surface quality (such as automobiles, home appliances, etc.), through-type shot blasting machines can provide fine surface treatment to achieve a polishing effect.

6. Remove welding spatter
Function description: During the welding process, welding spatter (i.e., welding metal particles) may adhere to the surface of the workpiece, affecting the appearance and quality. The through-type shot blasting machine can effectively remove these spatters and restore the surface quality of the workpiece.
Application example: On the surface of metal structures, pipes, etc. after welding, the shot blasting machine can remove welding spatter and welding residues to ensure the cleanliness and tidiness of the workpiece.

7. Removal of coatings and old paints
Function description: The through-type shot blasting machine can also be used to remove old coatings, paint layers, etc. on the surface of workpieces. Especially when re-coating is required, removing the old coating is a very important step. The through-type shot blasting machine can remove these coatings evenly.
Application example: On the surface of steel structures and old equipment in old buildings, the shot blasting machine can effectively remove old coatings and provide an ideal base surface for new coating or anti-corrosion treatment.

8. Automated processing of mass production
Function description: The through-type shot blasting machine is usually combined with a conveying system to form an automated production line, which is suitable for continuous processing of workpieces in mass production. This automated feature can significantly improve work efficiency, reduce manual intervention, and ensure the continuity and stability of production.
Application example: In foundries, steel mills, automotive parts manufacturers, etc., a large number of workpieces are cleaned and strengthened by shot blasting machines, and batch processing can be completed in a short time to meet the needs of large-scale production.

9. Improve painting and welding performance
Function description: The through-type shot blasting machine can roughen the metal surface and provide better adhesion for subsequent painting, coating or welding. The rough surface helps the combination of paint and metal surface, preventing the coating from falling off or welding from being weak.
Application example: After the steel surface is treated and then sprayed or coated, shot blasting can provide stronger adhesion for the coating and extend the service life of the coating.
10. Remove iron oxide scale
Function description: Iron oxide scale is easily formed on the metal surface, especially after the steel material is exposed to the air for a long time. The through-type shot blasting machine can remove these iron oxide scales and restore the metal surface to a smooth and clean state.
Application example: After the surface of steel products such as steel plates and steel pipes is cleaned, they can obtain better weldability, coating and corrosion resistance.
