　　The coloring treatment for metal nameplate production includes printing, oil spraying, electroplating, oxidation, baking paint coating, or local painting and other coloring methods. The baking process refers to applying three coats of primer and four coats of topcoat on the substrate of a metal nameplate. Each coat of paint must be placed in a dust-free and constant temperature baking room for baking. The effect of the painted metal nameplate reflects smooth edges and corners, the same color, uniform front paint film, and full color, with high decorative performance. Next, let's talk about the baking process for making metal nameplates:

　　The pre-treatment process for the surface of metal nameplates: 1. degreasing, 2. water washing, 3. rust removal, 4. water washing, 5. surface adjustment; 6. Water washing, 7. Phosphating, 8. Water washing, 9. Drying. Pre treatment → drying → primer coating → baking → topcoat coating → baking → inspection → packaging.

　　1. Using environmentally friendly high-quality paint for baking treatment, the baking room must be free of dust particles in the workshop, and the baking surface coating should be treated with three coats and three baking treatments, with a coating thickness greater than or equal to 35 microns.

　　2. Clean the residue on the surface of the metal nameplate, apply dust, and polish a series of surface cleaning treatments.

　　3. The paint color should meet the design requirements, and the surface paint film should be smooth and uniform, without any defects such as flow marks, wrinkles, orange peel, bubbles, gray layers, etc. that affect the decorative effect.

　　4. When the temperature reaches the set temperature, set the automatic stop burner. When the temperature drops to the set temperature, the fan and burner automatically restart to maintain a relatively constant temperature in the paint baking room. Finally, when the paint baking time reaches the set time, the paint baking room will be automatically shut down, and the paint baking process for making metal nameplates will end.
