Suspended chain shot blasting machine: Suspended chain shot blasting machine is suitable for shot blasting cleaning of small cast iron parts, cast steel parts, forgings and stamping parts, especially suitable for cleaning forgings and castings, to remove sand, rust, oxide scale, dirt, etc. on the surface of the workpiece, make the surface of the workpiece appear metallic, eliminate internal stress of the workpiece, improve the fatigue resistance of the workpiece, increase the adhesion of the paint film during painting, and ultimately achieve the goal of improving the surface and internal quality of the workpiece. Suspension chain shot blasting machines are divided into Q38 series suspension chain continuous shot blasting machines, Q48 series suspension chain step shot blasting machines, and Q58 series suspension chain stacking shot blasting machines.

8. Roller through shot blasting machine: It is a multifunctional shot blasting cleaning equipment for cleaning structural components, H-beams, steel plates, and other types of steel, with two types: flat roller and V-shaped roller. It can apply strong shot blasting to the surface of steel in its original state, removing rust spots, welding slag, and oxide layers. To achieve a uniform and consistent metallic luster surface with a certain degree of smoothness, in order to remove stress, improve the coating quality and corrosion resistance of steel structures and steel surfaces. This machine is suitable for stress relief and surface rust removal of steel plates, steel sections, steel pipes, metal structural weldments, steel products, railway vehicles, engineering machinery, bridge manufacturing industries, etc. It is the most widely used shot blasting machine.

9. Steel pipe inner and outer wall shot blasting machine: The steel pipe inner and outer wall shot blasting machine is a shot blasting cleaning equipment that integrates the inner and outer walls of the steel pipe. The outer wall is shot blasted, and the inner wall is shot blasted or cleaned according to the diameter of the pipe to remove the sticky sand, rust, oxide scale, dirt, etc. on the surface of the workpiece, make the surface of the workpiece appear metallic, eliminate internal stress, improve the fatigue resistance of the workpiece, achieve the goal of improving the surface and internal quality of the workpiece, and ultimately improve the corrosion resistance of mechanical products and metal profiles, improve the fatigue resistance of steel, and extend its service life; Optimize the surface process status of steel to achieve complete cleaning.

10. Steel cylinder specific shot blasting machine: a specialized shot blasting machine equipment for cleaning the inner or outer walls of steel cylinders, acetylene cylinders, oxygen cylinders, etc.

11. Anchor chain specific shot blasting machine: capable of one-time cleaning of anchor chains with diameters ranging from 22 to 150. It effectively improves the fatigue strength and corrosion fracture resistance of the anchor chain by ejecting countless high-speed projectile streams onto the surface of the anchor chain, thereby removing oxides and their surface attachments, and causing plastic deformation on its surface.

12. Wire specific shot blasting machine: mainly used for cleaning and strengthening the surface of small round steel and wire. Through shot blasting strengthening, not only can the rust on the surface of the workpiece be removed, preparing for surface non-destructive testing and anti-corrosion coating, but also the tensile strength of the workpiece can be enhanced, improving its service life. This series of equipment is equipped with shot blasting wheels centrally arranged on the top surface of the shot blasting cleaning room, using inclined V-shaped rollers to transport workpieces, and selecting and rotating the bars while moving forward. The cleaning effect is uniform, and the entire equipment is compact, easy to maintain, and can be configured with automatic loading and unloading mechanisms according to user requirements.

15. Steel plate/profile pretreatment line: The steel pretreatment line process refers to the processing technology of surface shot blasting and rust removal of steel before processing (i.e. raw material state), and coating with a layer of protective primer. Pre treatment of steel can improve the corrosion resistance of mechanical products and metal components, enhance the fatigue resistance of steel plates, and extend their service life; At the same time, it can also optimize the surface processing status of steel, which is beneficial for CNC cutting machine cutting and precision cutting. In addition, due to the relatively regular shape of the steel before processing, it is conducive to mechanical rust removal and automated painting. Therefore, using steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and the pollution to the environment.
