Bead Blast is a widely used surface strengthening process that enhances the fatigue strength of a workpiece by bombarding the surface with pellets and implanting residual compressive stress. This process not only improves the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of the parts, but also is convenient to operate. The types of bead blast treatment include steel shot, cast iron shot, glass shot, ceramic shot and so on. In addition, bead blasting is also used for parts that work under alternating stress, which can greatly improve the fatigue strength, such as automobile plate spring, spiral spring, shaft, connecting rod, etc. After shot peening, the life can be increased several times.

Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play the role of aesthetics and rust prevention. The main method used is hot-dip galvanizing. The main method of galvanized steel plate surface is hot-dip galvanized, and the production process of hot-dip galvanized plate mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection

Anodizing refers to the process of forming an oxide film on the surface of a metal material through electrolysis in an electrolyte solution. The anodic oxide film is formed by the combination of metal atoms and oxygen atoms, which has the characteristics of improving the wear resistance and hardness of the material, improving the corrosion resistance of the material and enhancing the insulation. Its treatment process includes pre-treatment (cleaning, oil removal, rust removal, etc., on the metal surface to improve the surface roughness and cleanliness), anodizing (the metal material as an anode, in the electrolyte power, so that the metal surface oxidation reaction, the formation of oxidation), post-treatment (the formation of oxide film cleaning, drying, etc.) To improve its corrosion resistance and appearance quality)

Powder coating is the use of powder spraying equipment to spray powder coating to the surface of the workpiece, under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece, forming a powdery coating; The powder coating is cured by high temperature baking and leveling, and becomes the final coating with different effects (different kinds of effects of powder coatings). Its advantages are high efficiency, less pollution, high utilization rate of paint and good film performance.
