What are the specific sheet metal repair steps for car dent repair?

The so-called car dent repair is also called micro-sheet metal. It is sometimes called the non-destructive repair technology of car dents. It is different from the traditional sheet metal painting process. It is based on the principles of optics, physics and mechanics. Due to various reasons, the dents of different sizes and depths are leveled and repaired, and then restored to the factory shape.

Step 1: Check if the car dent can be repaired

Even if the car owner can easily judge the repair type of the dent, after arriving at the 4S shop, it is still necessary to have relevant professionals to judge the quick repair, and it is necessary to estimate the repair time and related costs.

After the relevant personnel determine the scars of the car, the relevant personnel will first clean the appearance of the car, because in the process of repairing the car dent, it is necessary to constantly face the changes of the light and the surface of the steel plate, and also need to consider the car repair. And the inspection after completion, so the cleanliness of the car paint is very important.

Step 3: Car Restoration

There is no fixed pattern and sequence in the process of repairing car dents. Car dent repairing is a very meticulous technical job, which requires the repairers to have meticulous patience and care. The concave part also needs to be gently lifted from the inside to the outside by the relevant professional tools, and then the outer concave edge and the convex part are gently knocked with a small hammer, and mainly by knocking around the concave, It is very important to disperse the stress at the edges and corners of the depression so that the overall repair can be achieved.
