To identify the quality of automobile sheet metal parts

Automobile sheet metal parts generally refer to the metal shell of automobile, which is usually made of steel plate. On the basis of ensuring certain strength, it is the basic requirement to reduce the weight as much as possible. In addition to the role of protection and beauty, automobile sheet metal parts are also the main carrier of automobile gas resistance. Therefore, the quality and service life of automobile sheet metal parts will not only affect the appearance of the automobile, but also increase the resistance of air to the automobile due to the quality and deformation, which will reduce its economy.

To distinguish the quality of automobile body parts, we can start from the packaging, weight, welding process, painting process and fitting Chengdu when loading. It's very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after the car. We might as well distinguish from the packaging of the products in advance: generally, the products produced by small factories will not be printed with contact information and address, while the regular manufacturers will have steel seal, qualification and test label on the products, even if the consumers come out in the process of using in the future. At present, there can also be a way of safeguarding rights.

The sheet metal parts produced by regular manufacturers will adopt the operation mode of mechanical cutting and welding, and their welding points or cutting edges are smooth and flat, and the rough edges of the cutting hands will not be left.

Product weight is one of the inspection standards to measure the quality of sheet metal parts. In order to ensure the safety of automobile, the steel plate used in automobile sheet metal parts must reach a certain weight. The weight of the original sheet metal parts and the high-quality subsidiary 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, you will undoubtedly buy a small factory product. As for welding process, it is also a method to distinguish whether sheet metal parts come from large factories.
