First of all, professional automotive sheet metal and vehicle painting aims at repairing damaged vehicles, restoring their original appearance and keeping the hardness of metal materials as much as possible. However, some repair shops have omitted some work processes in order to cut corners, which has caused serious consequences. Then let's see what the consequences are:
1. When the vehicle passes through the sheet metal, the external galvanized layer will be crushed. If the heating process is applied in the sheet metal process, the metal material will be annealed and the strength and hardness of the metal will be reduced. If there is a collision afterwards, it is difficult to ensure the safety of the occupants in the car.
2. When the vehicle passes through the sheet metal, because the metal passes through the sheet metal, if the repair is not professional enough, the exterior is easy to be uneven, and cracks and depressions will appear after a long time, which will affect the appearance of the vehicle.
3. Whether it is sheet metal or painting the whole car, it will have an impact on the vehicle's preservation rate, because your car is not the original paint, and repainting will not achieve the original effect anyway.
4. painting the whole car means taking the whole body apart. If there is any mistake on the way, it may cause damage to the vehicle.
These are the serious consequences caused by nonstandard painting in automotive sheet metal and vehicle painting. Automotive sheet metal and the whole car painting will not be like this. If the maintenance master is experienced and dedicated enough, the above situation should not occur. Let's learn about the whole process of painting in automotive sheet metal:
1, determine the scheme
Before painting, the maintenance master needs to determine the maintenance plan according to the damage degree of the vehicle, and different solutions will be taken to different degrees.
2. Metal plate forming
Cutting, grinding, stretching, fire extinguishing and deoxidation are adopted for the deformed part. You should know that sheet metal is not only to restore the original appearance of the vehicle, but also to maintain the hardness of the metal material as much as possible.
Step 3 Scraping and shaping
After the sheet metal is corrected, the maintenance master will reshape the waistline of the car body and adjust its flatness by scraping and reshaping the car body.
4. Paint the surface
The paint spraying process is complex, which requires spraying the first primer, intermediate primer, paint mixing, topcoat spraying, paint drying and other processes, and must be carried out in a dust-free environment.
5, paint surface treatment
Although it has been painted, there will still be minor flaws, so the repair union will use extremely fine beauty sandpaper or polish it with a polishing machine to restore the luster of the car body.
