To distinguish the quality of automobile sheet metal parts, in general, we can start from many aspects such as packaging, weight, welding process, painting process, and the degree of fit when loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after delivery of the car. You may wish to judge from the product packaging in advance: generally, the products produced by small factories will not print the contact information and factory address, while regular manufacturers In addition to contact information and factory address, there will also be steel seals, qualifications and inspection labels on the products. Even if consumers have problems in the future use, they can also 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 automobiles, the steel plates used in automobile sheet metal parts must reach a certain weight. The weight of the original sheet metal parts and the high-quality sub-factory sheet metal parts should be almost the same, and if the sheet metal parts you buy are one-third lighter than the original sheet metal parts, then you will undoubtedly buy It will be a product of a small factory. As for the welding process, it is also a way to distinguish whether the sheet metal parts come from a large factory.

The sheet metal parts produced by regular manufacturers will adopt mechanical cutting and welding operations. The solder joints or cutting edges are smooth and smooth, and there will be no burrs left by rough cutting hands.

Many car owners think that the sheet metal parts need to be painted with the same color as the original car paint, so when purchasing sheet metal parts, they will ignore the painting process of the sheet metal parts, thinking that it is irrelevant, but this idea is not correct .

In order to prevent oxidation and rust, sheet metal parts need to be painted before leaving the factory. Indeed, the painting process after replacing the sheet metal parts can not only color the color, but also protect and prevent oxidation. If it is a sheet metal part of a small factory, if there is uneven adsorption and foaming in the painting process during production, it will affect the effect of the post-painting, causing it to fall off easily during use, cause corrosion, affect and damage The quality of sheet metal parts.
