Can Dalian shot blasting be used for surface treatment of mixed materials?

Dalian shot blasting, as a surface treatment technology, has a wide range of applications in industrial manufacturing and maintenance fields. It has the advantages of simple, fast, and effective removal of surface impurities and improvement of surface quality, but it also has certain drawbacks and limitations. In practical applications, it is necessary to reasonably select shot blasting materials and processing parameters to achieve ideal processing results.

Shot blasting can enhance fatigue life and resistance to fatigue cracks, as it can improve the surface adhesion ability of metal materials. In this way, even at special temperatures, the projectile can form a solid adhesion layer with the surface, thus preparing for subsequent plating or coating treatment. Shot blasting is often an important part of the pre-treatment process of metal materials before casting and forging. It can remove impurities from the material surface, reduce the occurrence of casting defects, and improve the roughness of the material surface, making it convenient for material processing.

Can Dalian shot blasting be used for surface treatment of mixed materials?

For the surface treatment of mixed materials, simply using shot blasting is clearly not enough. Generally speaking, a comprehensive use of various surface treatment methods such as sandblasting, electrochemical treatment, and grinding can achieve good surface treatment results. It is necessary to comprehensively consider factors such as the material, surface characteristics, and usage environment of the mixed material from multiple dimensions, and adopt a surface treatment method suitable for a specific mixed material according to the actual situation. Only by comprehensively applying multiple surface treatment methods can we truly achieve effective surface treatment of mixed materials, ensuring their good use effect and reliability.

In the shot blasting process, the selection of shot blasting materials and parameters such as jet velocity are very important. According to different application scenarios and needs, different types, shapes, and sizes of shot blasting materials can be selected to achieve different processing effects. Coatings with higher viscosity often require a rough surface, so it is necessary to choose larger shot blasting materials and higher jet speeds. On the contrary, thin coatings require a smooth surface, which often requires small and fine shot blasting materials and lower jet speeds.

In electrical and electronic manufacturing, shot blasting can remove the aluminum oxide layer from the metal surface, restore good conductivity and corrosion resistance, and improve the reliability and service life of electronic components. In the field of steel structural components and machine manufacturing, shot blasting can make the metal surface smooth and uniform, improving the material properties and quality of various components.
