What is the main purpose of painting in automotive sheet metal?
Hello, sheet metal painting is a kind of automobile repair technology, which is to repair the deformed part of automobile metal shell. For example, if the car body shell is knocked out of a pit, it can be restored to its original state by sheet metal, and then the deformed car metal surface can be restored to the same brightness as other intact places by spraying special paint.

After the automobile body is corrected by sheet metal, there are still some defects that can't be made up by sheet metal work. Even if new parts are replaced, there will be imperfections. In order to be more perfect and accurate, we must make up for the defects through sculpture technology. After the car is damaged due to deformation and other reasons, its flatness, wheel angle and lines need to be scraped and polished. This formula shows that scraping = restoring body skin = die product = die processing program. The body skin of any car is stamped with a mold, and we repair the body skin just like repairing the mold, so our scraping molding process should be connected with the mold processing, which is impossible for ordinary painters. Many painters who have worked for many years will sigh that it is easy to spray a car well, but it is difficult to do a good job, and it is difficult to grind a ball of ash in ten years. The person who said this may really understand what car painting is.
