Spray powder processing strengthens pre-treatment, including the quality of the workpiece substrate and the purification of compressed air, to improve the flatness of the coating.

Select suitable coatings based on the material and surface treatment requirements of the workpiece. Different coatings have different viscosity, solid content, and construction process requirements, which need to be selected according to the actual situation.

Passivation treatment is a commonly used metal surface treatment method that can be applied to various metal materials with the aim of improving the corrosion resistance and aesthetics of the metal surface.

Electroplating is a method of depositing metal ions on the surface of a substrate. Commonly used metals include chromium, nickel, copper, zinc, etc. Electroplating has the characteristics of uniform coating, smooth surface, corrosion resistance, oxidation resistance, etc., but the production cost is relatively high.

Metal surface passivation treatment is a step in chemical cleaning processes aimed at improving the corrosion resistance and extending the service life of metal materials.

The temperature of the plating solution will affect the deposition rate of chemical nickel. The higher the temperature, the faster the deposition rate, and vice versa. By controlling the temperature of the plating solution, the deposition rate of chemical nickel can be adjusted, thereby affecting the thickness of the coating.

After rough machining, semi precision machining is performed, including surface treatment of metal parts such as grinding and polishing, as well as cutting of metal parts to further improve their dimensional accuracy.

The operation methods of precision machining include: CNC machining technology: controlling the motion trajectory of the machine tool through computer programs, and machining parts on the ground

Nickel plating can make the metal surface shiny and flawless, with a good metallic texture and improved appearance aesthetics.

Metals may be corroded by chemicals such as acids and bases, which can accelerate their aging and damage. The oxide film formed on the metal surface after passivation treatment can resist chemical corrosion to a certain extent and maintain the stability of the metal's properties.
