High quality automobile sheet metal parts need mechanical production

The fitting degree of sheet metal parts during loading is also a key point to distinguish the quality of sheet metal parts. It will determine whether the final effect of loading is beautiful or not, and at the same time determine the difficulty of installation. Therefore, it is also a factor that many sheet metal maintenance technicians are very concerned about. If the fitting degree of sheet metal parts and the original car is low, such as the hole position cannot be aligned, the error of loading clearance and flatness is too large (the one-way tolerance of high-quality sheet metal parts in this respect should be controlled below 1.0mm), it can be basically judged that this is a non-conforming product from a small factory. Mr. Luo said that few car owners have noticed that a strong collision will cause slight deformation of the whole car body. At this time, if you install the sheet metal parts with large clearance, it will cause the car body to deform again, affecting the recovery of the damaged vehicle to its original appearance and quality.

Although experienced sheet metal technicians will eventually adjust the sheet metal parts to a better loading effect through drilling, grinding and welding, it will be more time-consuming and laborious. In addition, the quality and service life of the sheet metal parts are not as good as those made precisely by machinery. Therefore, it is better for car owners to select the original factory parts or the first-class auxiliary factory parts that are consistent with the gap of the original workshop when purchasing. When installing, they can be in place in one step to avoid or reduce the damage caused by the "secondary processing" of sheet metal masters.

It's not that selecting high-quality sheet metal products can be completely without 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.

Reminder:

1. High quality automobile sheet metal parts need to be produced mechanically, with smooth welding points and cutting edges, and no rough rough edges.

2. High quality sheet metal parts pay attention to the paint baking process, which requires uniform component, strong adhesion and good waterproof and oxidation resistance.

3. The gap between the first level auxiliary part "Xinyi" and the original car is only 0.3mm.

4. The hole position of poor quality sheet metal parts will not be aligned, so it is necessary to drill again.

5. The flatness of poor quality sheet metal parts shall be adjusted greatly.
