1, plastic also means scraping:

After the automobile body is corrected by sheet metal, there are still some defects that cannot be compensated by sheet metal work. Even if new parts are replaced, there will be imperfections. In order to be more perfect, we must use sculpture techniques to make up for the defects.

After the car is damaged due to deformation and other reasons, its flatness, wheel angle, lines and other parts need to be scraped and polished. With this formula, it is clear that scraping = restoring body skin = die product = die processing program, and any body skin of an automobile is stamped by a die.

We repair the body skin just like repairing the mold, so our scraping molding process should be consistent with the mold processing, which is impossible for ordinary painters.

2, painting, usually divided into three steps:

(1) Primer fills the sand marks and micropores at the bottom of the workpiece, increases the adhesion of the lower coating, and also has the function of defect indication.

(2) In the very important painting part of the primer, prepare a complete and flat working surface for the topcoat, complete the last procedure of all primer work, increase the adhesion of the intermediate layer and have a certain isolation effect, thus ensuring the quality stability of the topcoat.

(3) Top coat Top coat is divided into single-layer paint and multi-layer paint, which are color fixing layer and decorative protective layer. Single-layer paint is commonly known as plain paint, also known as ordinary paint, and can be completed in one layer.

Multi-layer paint is divided into silver powder series paint and pearlescent series paint, which is completed by two-layer and multi-layer construction technology. Silver powder paint adopts special aluminum material, which has high protection, strong outdoor stability and strong observability. Pearl series paint is made of mica and shells through high technology, which is a kind of high-grade paint with rich colors and strong decoration.

Need to know:

Sheet metal correction is the preliminary plastic work of painting. We compare it to the human body. A perfect human body is like a model's figure, which symbolizes luxury fashion. If you let a man with a broken limb wear it, it's nothing, and it will be eclipsed. Then if you let a fashion model wear it, it will look dazzling and noble.

Very simple, how can a twisted car body set off the brilliance of paint? Many painters think that sheet metal is not their job, but I don't think so.
