The use of shot blasting cleaning technology in the coating production line is of great significance for castings such as car frames. On the one hand, during the casting process, impurities such as oxide scale and sticky sand will form on the surface of the car frame. Shot blasting cleaning can effectively remove these impurities, exposing the metal body on the frame surface and providing a good substrate for subsequent coating, ensuring better adhesion between the coating and the frame surface, and avoiding problems such as coating peeling and blistering. On the other hand, the shot blasting process can create a certain roughness on the surface of the frame, increase the contact area between the coating and the surface, further improve the adhesion performance of the coating, and thus enhance the anti-corrosion ability and appearance quality of the frame. Moreover, shot blasting cleaning can also strengthen the surface of the frame to a certain extent, improve its mechanical performance, and extend the service life of the frame.

The functional feature of the drum type shot blasting machine is that it can perform comprehensive shot blasting cleaning on small parts, effectively removing impurities such as oxide scale and rust on the surface of the parts, and strengthening the surface of the parts to improve their fatigue strength and other performance. Moreover, due to the enclosed structure of the drum, it can effectively control the splashing of projectiles and reduce pollution to the working environment.

The functional advantage of the track type shot blasting machine lies in its significant cleaning effect on the surface of castings and forgings, which can effectively remove surface sand, burrs, etc., and improve the surface quality of workpieces. The smooth rotation of the track enables the workpiece to receive uniform projectile impact in the shot blasting chamber, ensuring consistent cleaning effect. Meanwhile, the track type shot blasting machine has a relatively large load-bearing capacity and can handle workpieces of a certain weight.

The main function of the hook type shot blasting machine is to meet the shot blasting needs of large workpieces. It can adjust the lifting capacity of the hook and the size of the shot blasting chamber according to the size and weight of the workpiece. During the shot blasting process, various parts of the workpiece can be covered by the shot through actions such as lifting and rotating the hook, achieving comprehensive cleaning and strengthening. For some large workpieces with complex shapes, the hook type shot blasting machine can also perform shot blasting tasks well.

The outstanding function of the through type shot blasting machine is to adapt to large-scale continuous production, and its conveying system can be adjusted according to the production pace to achieve rapid conveying and shot blasting of workpieces. It can perform shot blasting cleaning on workpieces of different specifications, and adjust shot blasting parameters such as shot speed, flow rate, etc. according to the material and surface requirements of the workpiece to achieve the best shot blasting effect. The automation level of the through shot blasting machine is relatively high, which can reduce manual intervention, improve production efficiency and product quality stability.
