Detailed explanation of the process flow of the paint shop

In the development of modernization, the coating process is no longer a literally "spray paint" process. The reason why the coating process is called a process is that it is unusual. The role of the current coating is to meet the public's aesthetic needs for a diverse appearance, and the safety and service life of the vehicle performance will not be ignored.

In the development of modernization, the coating process is no longer a literally "spray paint" process. The reason why the coating process is called a process is that it is unusual. The role of the current coating is to meet the public's aesthetic needs for a diverse appearance, and the safety and service life of the vehicle performance will not be ignored. The basic principles and operation methods of the coating process are as follows.

Detailed explanation of the process flow 1. Surface treatment: It can also be called pre-treatment. This is the step of "laying the foundation" for the coating process. The main processes are degreasing, rust removal, phosphating and other steps. Remove impurities on the surface of the workpiece or change the material of the workpiece surface (form an oxidized coating on the surface of the workpiece). These are to make the subsequent coating stronger and increase the adhesion of the paint surface. 2. Scrape putty: Use putty powder and water to mix into a filler, and use a scraper to apply putty on the incomplete surface of the workpiece to be painted. If there are slight bumps on the surface of the product, you can also use sandpaper to polish it at this stage; this process mainly plays the role of filling and leveling, reducing the generation of defective products and directly reducing production costs. 3. Spraying primer: Primer is a key step in the painting process. The role of primer is to improve the anti-corrosion ability of the car body. It will also affect the subsequent painting of the topcoat and directly affect the appearance quality. 4. Drying: After the primer is dried, the product needs to be transferred to the drying furnace, because the coating needs to be dried and cured quickly. Rapid curing of the paint surface affects the surface quality of the paint surface and improves production efficiency. 5. Spraying topcoat: The topcoat is the "face" of the car's appearance and is also an intuitive factor for consumers to choose consumption. Through topcoats of different colors and processes, a variety of effects such as gloss, matte, and color matching can be achieved. 6. Drying (topcoat drying): After the primer, it needs to be dried. Similarly, the topcoat needs to be dried in the curing furnace after spraying to achieve the best effect.

Precautions 1. The operator must be professionally trained or have rich practical experience, understand the principles of mechanical operation, and be familiar with the operating essentials and safety precautions of each process. 2. Regular maintenance and regular cleaning of the painting production line workshop environment to avoid the influence of impurities and dust on the coating quality. 3. Strictly control the drying temperature to prevent the coating from overheating or burning. If you want to operate a coating production line well, you need to constantly learn and understand the process flow and operating principles. I hope that the seven major process flows of the coating workshop shared in this article can inspire and help readers.
