For example, the repair price of paint-free dent repair technology is around 300 to 350 yuan. In a general car door dent repair company, it takes about 10 to 90 minutes to repair a car door dent, and the cheapest one needs 130 yuan for one injury. The maintenance cost is extremely low. Excluding the funds invested in tools, equipment and technology, the cost is almost zero and the profit is extremely high.
The so-called automobile dent repair technology is also called micro-sheet metal, and sometimes it is also called seamless nondestructive technology. Anyway, repairing the concave surface of the car body does not have to destroy the original car paint. The principle is actually very simple, that is, based on optics and mechanics, using the lever principle, the pits with different depths are slowly restored to their original appearance.
As long as the potholes on the door surface do not fall off and the paint does not fall off, the professional tools and equipment used in the repair technology can be repaired without sheet metal and paint. After repair, the color and smoothness of car paint and the hardness, strength, toughness and durability of car body steel plate all meet the technical parameters.
In a word, when faced with the problem of how much to repair the car door sag, different repair technologies will affect the repair price according to different regions, different models and different damaged areas, but generally speaking, the repair price of the car door sag is between 200 yuan and 500 yuan.
