Painting after replacing the automobile sheet metal parts

The sheet metal parts produced by regular manufacturers will be mechanically cut and welded. The welding points or cutting edges are flat and smooth, and rough edges of rough cutting hands will not be left.

Many car owners think that the body parts need to be painted with the same color as the original car, so they will ignore the painting process of the body parts when purchasing the body parts, thinking that it is irrelevant, but this idea is incorrect. In order to prevent oxidation and corrosion, sheet metal parts need to be painted before delivery.

It is true that the painting process after replacing the sheet metal parts can not only color the parts, but also protect and prevent oxidation. However, if the sheet metal parts of small factories have uneven adsorption and blistering in the painting process during production, the effect of post painting will be affected, resulting in easy falling off and rusting during use, affecting and damaging the quality of the sheet metal parts.

To distinguish the quality of sheet metal parts, generally speaking, we can start with packaging, weight, welding process, painting process and the degree of coincidence during loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after the delivery of the car. It may as well be distinguished from the packaging of the products in advance: generally, the products produced by small factories will not be printed with the contact information and address, and the products will also have steel seals, qualifications and testing labels. Even if consumers have problems in the use process in the future, they can have a way to protect their rights.

Product weight is one of the inspection standards to measure the quality of sheet metal parts. In order to ensure the safety of the automobile, the steel plate used in the automobile sheet metal parts must reach a certain weight. The weight of original sheet metal parts and high-quality sub factory sheet metal parts should be almost the same. If the sheet metal parts you buy are one third lighter than the original sheet metal parts, it is no doubt that you will buy a small factory product. As for the welding process, it is also a way to distinguish whether the sheet metal parts are from large manufacturers.
