The sheet metal part of a car generally refers to the metal shell of the car, which is usually made of steel plates. On the basis of ensuring a certain strength, it is the basic requirement to reduce the weight as much as possible. In addition to protecting and aesthetically pleasing, automotive sheet metal parts are also the main carrier for vehicles to withstand gas resistance. Therefore, the quality and life of automobile sheet metal parts not only affect the appearance of the automobile, but also increase the resistance of the air to the automobile due to quality and deformation, which reduces the economy.
Sheet metal parts and their classification
According to the manufacturer, automobile sheet metal parts can be divided into two categories: original parts and auxiliary parts. The so-called “original factory” generally refers to the supporting parts for the OEM; The price of most original parts is higher than that of replacement parts. Most people think that the original parts replaced at the special maintenance station or the original parts bought in the auto parts market should be the same as the original car. In fact, there will be large or small differences.
For example, the “original” sheet metal parts are also divided into several levels: the first level is of good quality and is a special loading part, that is, the original car, which cannot be bought outside at all; the second level products are for special supply In the repair station, except for the possible gaps in the process of installation or replacement, the product itself is not much different from the first-class; the third-class is the accessories products that flow to the retail market, although the original parts are still sold. High price, but in fact its quality can not be compared with the real original car.
The product quality of the “auxiliary factory” parts is also mixed: the products of the first-level “auxiliary factory” automobile sheet metal parts are almost comparable to the original parts, and this type of products are mostly from manufacturers with strong capital and hardware strength, from material selection to The mechanical operation of the assembly line can be guaranteed to be standardized; the second-level “auxiliary factory” parts use materials and manufacturing processes that are inferior to the first-level products; and the latter category is sloppy, with no quality at all, and only rely on low prices. deceive consumers.
Some repair stations operate illegally. The so-called original parts are actually low-quality “auxiliary parts” wholesaled from the auto parts market. In order to make huge profits, they will sell them to car owners under the banner of “original”, and their prices will naturally be higher. Much higher than the auto parts market. So, how to distinguish the pros and cons of sheet metal parts? To this end, we consulted senior technicians who have many years of experience in repairing automotive sheet metal parts.
