A brief discussion on the baking process of metal nameplate making
Metal nameplate production coloring processing has printing, oil spraying, electroplating, oxidation, baking paint coating, or local coating paint and other coloring methods.
Baking process refers to the metal nameplate substrate on three primers, four topcoats, each paint, need to be placed dust-free oven.Paint metal nameplate effect reflects smooth edges and corners, the same color, front paint film uniform, full color, with a higher decorative performance.
Next, we will talk about the metal nameplate production of baking process:
Pretreatment process of metal nameplate surface :1. Oil removal, 2. Water washing, 3. Rust removal, 4. Water washing, 5.6. Water washing, 7. Phosphating, 8. Water washing, 9. Drying.Pretreatment → drying → primer painting → baking → finish painting → baking → inspection → packaging.
1. Adopt environmental protection high quality paint baking treatment, baking room must be no dust particles workshop, baking paint surface coating three coating three baking treatment, coating thickness greater than or equal to 35 micron.
2. A series of surface cleaning treatments including cleaning the residue on the surface of the metal nameplate, patching dust and polishing.
3. Paint color should meet the requirements of the design scheme, the paint film should be smooth and uniform, not allowed to appear flow marks, wrinkles, orange peel phenomenon, bubble, ash layer and other defects affecting the decorative effect.
4. When the temperature reaches the set temperature, set the burner to stop automatically.When the temperature drops to the set temperature, the fan and burner automatically restart, so that the temperature in the paint room remains relatively constant.
Finally, when the baking time reaches the set time, set the baking room to automatically shut down, the metal nameplate baking process is finished.
