2020-04-07 15:33:35

The sheet metal parts of automobile 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 not only affect the appearance of automobile, but also increase the resistance of air to automobile parts due to the quality and deformation, so as to reduce its economy.

1. Sheet metal parts and their classification

Automobile sheet metal parts can be divided into two categories according to the manufacturer: original parts and auxiliary parts. The so-called "original factory" generally refers to the matched loading parts for the whole vehicle factory; "Auxiliary Factory" refers to the non matched parts produced by non matched manufacturers. The price of most of the original parts is higher than that of the auxiliary parts. Most people think that the original parts replaced in the special maintenance station or purchased in the auto parts market should be the same as the original car, in fact, there will be big or small differences.

2. How to distinguish the advantages and disadvantages of sheet metal parts

According to the master of automobile sheet metal parts processing factory, to distinguish the quality of sheet metal parts, we can start from many aspects, such as packaging, weight, welding process, painting process and fitting degree when loading. It's very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after delivery. 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 in addition to contact information and address, even if the consumers come out in the process of use in the future At present, there can also be a way of safeguarding rights.

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. 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.

Many car owners think that the body parts still need to be painted with the same color as the original car, so they will ignore the painting process of the body parts when choosing the body parts, which is irrelevant, but this idea is not correct. In order to prevent oxidation and corrosion, the body parts need to be painted before leaving the factory. Indeed, the painting link after replacing the body parts can not only color them, but also protect and prevent oxidation. However, if it is a small factory body parts, the painting treatment during production has uneven adsorption and foaming, which will affect the effect of post painting In the process of using, it is easy to fall off, lead to corrosion, affect and damage the quality of sheet metal parts.

The above is to distinguish the processing quality of automobile sheet metal parts, hoping to give some help to the owners who need to buy sheet metal parts. Of course, it's not that selecting high-quality sheet metal products can be completely free of consideration. Like many parts of the car, sheet metal parts also need reasonable use and maintenance. It is the key to prolong the service life of sheet metal parts to reduce the outdoor parking and driving in sand water as far as possible, and regularly paint the inner side of sheet metal parts to prevent corrosion.
