What are the similarities and differences between Dalian shot blasting and sandblasting processing?

Dalian shot blasting is a commonly used surface treatment process, widely used in various industries for component processing, which can effectively improve the surface quality and service life of workpieces. It is an important metal surface treatment method. With the continuous progress of technology, shot blasting technology is also constantly innovating and developing, providing more effective and efficient solutions for the surface treatment of workpieces.

Shot blasting can effectively remove defects such as oxide layer, dirt, and rust on the surface of the workpiece, improving the surface smoothness and roughness, thereby improving the quality and appearance of the workpiece surface. Shot blasting can effectively remove oil and impurities from the surface of the workpiece, improve the cleanliness and roughness of the workpiece surface, thereby increasing the adhesion and corrosion resistance of the coating. Shot blasting removes defects such as oxide layer and rust on the surface of the workpiece, effectively preventing surface corrosion and fatigue cracks, and prolonging the service life of the workpiece.

What are the similarities and differences between Dalian shot blasting and sandblasting processing?

The principles of shot blasting and sandblasting are different:

Shot blasting processing is the process of dropping metal pellets, sand, glass beads, and other particles onto the high-speed rotating blades of a windmill. These particles are quickly thrown onto the surface of the object using wind power to remove surface dirt and increase roughness.

Sandblasting processing is the process of spraying high-speed abrasive particles onto the surface of an object, performing cutting, polishing, and other treatments to improve surface roughness and cleanliness.

The application scope of shot blasting and sandblasting is different:

Shot blasting is suitable for surface treatment of various metal materials, such as steel, aluminum alloys, etc. It is mainly used to remove oxide skin, clean welding slag, improve surface smoothness and adhesion.

Sandblasting is suitable for a wider range of materials, such as metals, plastics, ceramics, etc. It can also be used to treat the surface of complex shaped workpieces, achieving effects such as rust removal, surface polishing, and increased gloss.

The accuracy and efficiency of shot blasting and sandblasting are different:

Shot blasting is generally used for surface treatment that requires high roughness, with high processing efficiency but low accuracy.

Sandblasting is relatively more precise, and controlling the particle size and pressure can adjust the machining accuracy, but the processing efficiency may be slightly lower than shot blasting.

Shot blasting is commonly used for surface treatment of components in industries such as automobiles, machinery, ships, and aerospace. It can effectively remove impurities such as surface oxide layers, rust, and welding slag, improving the surface quality and service life of workpieces. Shot blasting processing can also perform various treatments on workpieces, such as shot blasting rust removal, shot blasting strengthening, shot blasting shaping, and shot blasting slag removal, suitable for workpieces of different shapes and materials.

The process principle of shot peening is to use a shot peening wheel to spray granular pellets at a certain speed from a certain height onto the surface of the workpiece. Through impact, friction, and cutting, surface oxidation layers, rust, oil stains, and other stains are removed. At the same time, it can also improve the surface roughness and increase the adhesion of the workpiece surface. Shot blasting usually uses steel shot, iron shot, aluminum shot, glass shot, etc. as the spraying medium, and its selection depends on factors such as workpiece material, surface treatment requirements, and processing effect.
