How does Dalian shot blasting process remove surface defects and defects of materials?

Shot blasting is a common surface treatment method that uses a high-speed rotating shot blasting wheel to shoot metal shot blasting particles towards the surface of the workpiece being treated, in order to remove surface dirt and oxide layers, while improving surface roughness. Shot blasting is widely used in industries such as casting, automotive, aerospace, metallurgy, etc. It has the advantages of high efficiency, environmental protection, and improving workpiece quality. However, it also has some drawbacks, such as generating noise and dust, which may cause deformation on the surface of the workpiece, etc. In practical applications, it is necessary to choose appropriate shot blasting processing methods based on specific material and process requirements to achieve good surface treatment results.

Shot blasting has a series of advantages. It can effectively remove various defects on the surface of the workpiece, such as oxide layers, rust, scratches, etc., fundamentally improving the quality of the metal surface. Secondly, shot blasting can increase the surface roughness of the workpiece, improve the adhesion between the coating and the coating, and make the coating more firm. In addition, shot blasting can also improve the strength and wear resistance of metal materials, extending the service life of products. Shot blasting is an environmentally friendly and energy-saving surface treatment method because it does not produce chemical waste liquid or secondary pollution.

How does Dalian shot blasting process remove surface defects and defects of materials?

Shot blasting can remove the oxide layer on the surface of materials. On the surface of many materials, such as steel, aluminum, copper, etc., it is easy to form an oxide layer, which affects the mechanical properties and processing performance of the material. By shot blasting, the oxide layer can be completely removed, the surface roughness and cleanliness of the material can be improved, and the bonding strength with other substances can be enhanced.

Secondly, shot blasting can remove dirt and grease from the surface of the material. In industrial production processes, various types of dirt and grease are often attached to the surface of materials. These dirt not only affect the surface quality of materials, but also reduce the adhesion and uniformity of subsequent processes such as painting and spraying. Shot blasting processing can effectively remove these dirt and grease through the high-speed impact of the shot blasting agent, making the material surface clean and pollution-free.

Thirdly, shot blasting can remove rust and fragile layers on the surface of materials. In the processing of some metal products, prolonged exposure to humid air can lead to corrosion on the metal surface, thereby reducing the service life of the material. Meanwhile, some metals may form uneven and fragile oxide layers on their surfaces after heat treatment or welding. By shot blasting, rust and fragile layers can be completely removed, restoring the overall performance of the material, and providing ideal surface conditions for subsequent painting, welding, and other processes.

The technical points of shot blasting processing include the selection of shot blasters, the selection of shot blasting materials, and the control of shot blasting parameters. The selection of shot blasting equipment should be based on the specific size and shape of the workpiece, as well as the process requirements, to ensure the effectiveness of shot blasting while not damaging the surface of the workpiece. The selection of shot blasting materials should be based on the material and requirements of the workpiece to achieve cleaning and treatment effects. The control of shot blasting parameters includes shot blasting speed, shot blasting flow rate, shot blasting time, etc., which need to be adjusted and controlled according to specific process requirements to achieve good processing results.
