Car shell dent repair, how to repair car shell dent

If the body is depressed and painted, it is recommended to paint sheet metal, about 300 to 500, but if there is no paint off and you are very concerned about the original paint, you can try the paint-free car dent repair technology, no need to destroy the original car paint for body concave repair, the principle is actually very simple, it is based on optics and mechanics, and the use of the lever principle to slowly restore the pits of different depths to the original appearance, look at the following picture You can see it at a glance.

It depends on the size of your depression, similar to the one in the picture, about 300 yuan.

<> the picture below is the repair effect of our sharkskin car dent repair direct store**, the first one**The black border area on the left is the appearance of the original painted body, and the right is the appearance of the repaired body, how can you feel the specific effect, but after all, there are so many stores in the country that the car dent repair can not be generalized, so I suggest that you still go to the regular brand store to repair, so that the technical level will be *** and** fixed, unlike small shops that will only shout prices all over the sky.

Automobile dent repair technology uses a variety of technical means such as strong magnetism, strong bonding, and optical lever to decompose, micro-repair, pull and flatten the car depression part point by point, and restore the car depression without moving the original car paint. The force of the tool acts directly on the back steel plate of the concave paint surface of the body, so as not to destroy the paint of the car, so as to achieve the effect of no painting.

Non-destructive repair is limited to the dents where the paint is not damaged, if the paint is cracked, it can only be painted, if it is only a slight scratch and dent, it is recommended to repair the car dents.

Dedge repair is an automobile pit repair technology on the basis of not destroying the original paint, and there are two forms of treatment:

One is manual treatment, with a special hook to pry out, pry out the pit, and then use a rubber hammer to knock back, with light to level, such treatment is basically no damage to the car paint, but the edge and the ribbed place can not be treated, more masters are reluctant to let the owner see when construction;

One is machine processing, using the machine to suck out the concave part outside, and then use a rubber hammer to knock back, and the rib part can basically be repaired, and it is operated in front of the owner.

1. The shell of the car is made of iron sheet and plastic, and the front and rear bumper of the car are generally plastic. The plastic will soften when it comes into contact with heat, so according to this principle, the piece that hits the dent can be heated and ejected.

2. First of all, we need to boil a large bucket of hot water, and then add water to the recessed place with a spoon to heat the hot water.

3. The process of heating with hot water is long. Because the concave plastic needs to be heated to a certain extent before it becomes soft in order to achieve the effect.

4. After the plastic is heated to a certain extent, it is from the top hood. Push it out with your hand until the recessed piece protrudes and restores.

Hello, the first step, for a small car with elastic deformation: this deformation does not change the mechanical properties of the metal itself, and when the external force disappears, the workpiece recovers on its own.

The second step is to deal with plastic deformation for the depression of the car shell: this deformation destroys the mechanical properties of the metal itself, and when the external force disappears, it cannot return to the original state by relying on its own ability, so we need to restore it artificially. Obviously, the deformation of the car body is generally plastic deformation, otherwise, there is no need for maintenance personnel to work.

During maintenance, the key to successful maintenance is to analyze the case of the depression and grasp the focus point of the depression and the magnitude and direction of the force. And the degree of depression is different, and the repair plan is also different.

The third step, for the treatment of car shell depression, maintenance solution, if it is only a slight depression, the material area has not changed, you can use a horn and a suitable sheet metal hammer to slowly correct; If it is deep and the material is stretched, the area is larger than the area before deformation, and the sheet metal hammer and horn can be roughly knocked flat first, and then repaired with filler.

The fifth step is to find a 4S shop or after-sales store if it doesn't work, and entrust them to carry out effective maintenance and treatment of the car shell dentation.

Hope mine can help you, hope!

This belongs to the sheet metal project of car beauty, like our side has a separate project of learning, a professional team of teachers and facilities and equipment, you can get started quickly, you can consult and understand. With the gradual increase of motor vehicles, especially private cars, an auto beauty maintenance industry known as the "best industry" has made more and more people pay attention to it. At present, the booming auto market will surely drive the rapid development of the auto beauty service industry, and the auto beauty industry has become an industry with considerable investment value.

Professional people do professional things, go to the repair shop to have a look!

1. Because the shell of the car is made of iron sheet and plastic material, the depression can be heated through the principle of thermal expansion and cold contraction. 2. Repeatedly pour hot water on the depression with hot water. 3. After the depression is heated to a certain extent, push it outward by hand and gradually let it recover.

Mild depressions can be gently corrected by cushioning and then using a suitable sheet metal hammer, while deep depressions need to be roughly flattened with a sheet metal hammer and then repaired with fillers.

With the development of social science and technology, automobiles can be said to have entered every household. This also affects a lot of vehicles on today's roads, in these driving processes will inevitably affect the collision of the car for various reasons, if it affects the shell dentation, what should be done?

Automobile shell dent repair method 1, because the car shell is made of iron sheet and plastic material, it is natural that the depression can be heated through the principle of thermal expansion and cold contraction.

2. Boil a large bucket of hot water, and then repeatedly pour hot water on the depression.

3. After the depression is heated to a certain extent, you can push it outward by hand from the position of the engine cover, and gradually let it recover.

Pay attention to what hot water heating repair is relatively slow, when the engine cover is pushed by hand and has no effect, it needs to continue to heat it in place.

In addition, if the depression is mild, it can be gently corrected with a cushion cushion and then with a suitable sheet metal hammer, while if it is a deep depression, it needs to be roughly smoothed with a sheet metal hammer before it is repaired by filling.

The best result of repairing the dent of the car shell is to repair it, so that not only can people not see the difference from the appearance, but also the paint and arrangement of the car that it has knocked off are basically the same, which is the real repair effect.

The repair method of the dent of the car shell is: 1. Use hot boiling water to continuously pour it on the body of Naibaohui to make the material soft and push outward; 2. Absorb the soft suction cup to the depression and pull it out. The methods of scratch repair of car shell are:

1. Wipe the scratched parts with a mixture and wax them in a straight line; 2. Lightly apply toothpaste to the scratches, and then wipe it several times with a cotton cloth against the dust sail clockwise; 3. Wash and dry the vehicle and apply rust remover to the scratches. The maintenance method of the car shell is Chang A: 1. When washing the car, it should be carried out after the engine is cooled; 2. Reduce vehicle exposure; 3. Clean up the stains on the body in time; 4. After rainwater washing, it should be cleaned with clean water to avoid acid rain corrosion; 5. Waxing or glazing.

1. For the elastic deformation of some automobiles: this deformation does not change the mechanical properties of the metal itself, and when the external force disappears, the workpiece will recover by itself.

2. For the plastic deformation of some automobile shell collisions: this deformation destroys the mechanical properties of the metal itself, and when the external force disappears, it cannot return to the original state by relying on its own ability, so we need to restore it artificially. During maintenance, the key to the success of maintenance is to analyze the case of the depression and grasp the force point and the magnitude and direction of the force of the depression.

And the degree of depression is different, and the repair plan is also different.

3. After the collision of the car shell, the shell is dented, and the maintenance solution, if it is only a slight dent, the material area has not changed, and it can be slowly corrected with a horn and a suitable sheet metal hammer.

4. If the collision fluid of the car shell occurs, and there is a depression in the shell, what we should do, such as deeper, and the material is stretched, and the area is larger than the area before the deformation, you can first use sheet metal dust to bury the hammer and the horn roughly knock it flat, and repair it with filler.

5. The car shell collides, there is a dent in the shell, if we have some tools and appliances that we can handle in our hands, we can deal with it ourselves, if we don't have tools on hand, it is more difficult and troublesome to deal with by ourselves, you can go directly to the after-sales maintenance shop or car repair shop.

1.Repair method of car body depression: the place where the depression is deep or the area is large can be pulled.

Insert the glue stick into the glue gun, heat it for a few minutes, and hit it on the suction cup from the center to the periphery. Use the residual temperature to stick the suction cup on the force point with a large depression, and then connect the T-shaped device to the suction cup head, and pull out the suction cup forcefully; Use a hook to push the concave out and treat the slightly convex part with a rubber hammer.

2.The repair of dents in the car shell is to restore the dent part of the car paint to its original shape.

3.Under normal circumstances, whether it is an acute angle or an obtuse angle depression, the main thing is that the depression without paint can be repaired as before, the hail crater can be repaired perfectly, and the corners and AB pillars are not easy to repair.

Car dent repair:

1. After the car is delivered to the 4S store, it will be tested and registered first to determine the parts that need to be repaired.

2. Before the repair process begins, the car will be sent to the calibrator for measurement. The function of the calibrator is to adjust the instrument according to the size parameters of different models, when the vehicle to be repaired is placed on the corrector, you can clearly see the place where there is a gap with the original size, and it is also convenient to repair accurately according to the original appearance of the car. It is reported that at present, only Changyue in Guangzhou is equipped with this calibrator.

3. A complete set of professional automobile repair molds and shape quick repair machines are used for sheet metal repair. By welding the mold to the surface of the car, a stretching operation can be carried out to pull out the recessed part and restore the original appearance of the car. Different sizes and shapes of depressions require the use of different models and combinations of car repair molds, and require the maintenance master's rich experience and professional skills to operate.

4. After the car restores its original shape, due to the small holes left in the welding place, the car paint needs to be polished and filled, according to the master, Changyue's grinding method is to use putty for dry grinding, compared to many repair shops using wet grinding technology, dry grinding adhesion is stronger, and the final effect is better. In addition, Changyue leads the industry in introducing the advanced dust collection system from Germany, and the dust generated during the grinding process will be automatically and continuously collected, so as to improve the working environment of workers while obtaining good grinding results.

5. After grinding, the car should be painted, in order to make the car paint uniform, the paint can not only be applied to the polished place, but the entire area needs to be painted. The weather in Guangzhou is humid, the paint is more difficult to dry, in order to make the effect better, Changyue will use the baking lamp for baking, according to reports, the baking lamp used by Changyue is the IRT baking lamp imported from Sweden, which can automatically adjust the distance and temperature, and can achieve the shortest drying time in the entire industrial field in the world.

6. After the paint is dried, reinstall the dismantled part on the car, and do a vehicle inspection to ensure that the appearance part is free of defects and the internal parts are operating normally. Finally, polishing the paint can make the car look like a new car.
