Why spray the perforated mesh?

Do you know why it is necessary to carry out the spraying process after the protective punching mesh is processed and formed, because the surface spraying after the processing and punching can play a beautiful, anti-corrosion and protective effect on the workpiece.
The principle of punching molding spray technology is that when the plastic powder is charged by a high-voltage electrostatic device, and under the action of an electric field, the paint is sprayed on the surface of the punching mesh, and the powder will be uniformly adsorbed on the surface of the punching mesh to form a powdery coating.
The powder coating is leveled and solidified after being baked at high temperature, and the plastic particles will melt into a dense final protective coating with various effects; it is firmly attached to the surface of the perforated mesh.
Electrostatic powder spraying is used for punching forming mesh spraying, and powder spraying is to use electrostatic generator to make plastic powder with electricity. Adsorbed on the surface of the iron plate, baked at 180°C to 220°C, and the powder is melted and attached to the metal surface.
The punching and forming mesh is sprayed with plastic, which has no pollution to the environment and no harm to the human body. The characteristics of spray plastic are bright appearance, higher strength and mechanical strength, and higher corrosion resistance and wear resistance. The colors of spraying are white, blue, green, silver, yellow, etc.
