What are the precautions for repairing the door dent

1. The door depression can be repaired by sheet metal painting, and the process is as follows: Sheet metal treatment: The dent on the body must be completed by hammering and welding to restore it to its original state.

Putty treatment: The uneven area after sheet metal should be smoothed with a kind of clay (usually called putty). Grinding treatment:

It is necessary to use different types of sandpaper sandpaper to trim the uneven surface of the putty. Primer spraying: To prevent rusting, a layer of anti-rust paint is also sprayed.

Color matching: Before painting, in order to make the body color consistent, it is necessary to adjust the paint color according to the color plate. Spray paint:

Spray the paint on the damaged surface. Paint: The paint needs to be dried quickly, and the vehicle needs to enter the paint room for "drying".

Install Parts: Parts that are removed before installing the sheet metal.

Second, if the door dent is not damaged to the car paint, you can buy a set of paint-free car dent repairer to repair it yourself. If the paint has been damaged, then it is necessary to spray paint, go to the regular store to spray paint, and there will be no cracks in the paint surface in the future.

The most direct and traditional method is to use thermal expansion and contraction, directly splash hot water to heat the injured and dented parts of the car, and then press them with your hands or with a pry bar to push out the dent little by little to achieve the effect of repair.

2. The same is the use of the principle of thermal expansion and contraction, you can choose to use the hair dryer to heat, so that the efficiency is higher, at this time, you can cooperate with two people, while heating, while squeezing, speed up the repair of the car time, if the car depression is relatively large, you can appropriately increase the number and temperature of the hair dryer, increase the heat transfer, and then, press internally to help recovery.

If the door is dented, it is necessary to go to the repair shop to renovate and repair it and then polish and spray paint, and the general cost is 400 yuan.

<> first insert the hot melt glue stick from behind the applicator gun and pull the trigger a few times to let the glue stick enter completely. Plug the glue gun into the power socket, preheat it for a minute, let the hot melt glue melt thoroughly, select the appropriate traction gasket according to the diameter of the dent, pull the trigger of the glue gun, and coat the traction gasket with the molten glue. Align the traction spacer coated with hot melt adhesive to the center of the depression and gently press it with your hand.

After a few minutes, the center hole of the tension bridge is aligned with the shaft of the traction gasket and is set.

Pull out the gasket evenly and forcefully, and it slowly recess up.

<> due to the remote location, the tool hook could not reach in from the side, so the door could only be removed, and the suitable tool was found to prepare to dismantle the door.

First of all, remove a few fixed screws hidden in the interior panel, and then break the interior panel evenly, our sharkskin dent repair master has an average repair experience of not less than three years, so the interior panel is removed by three times five divided by two, and you must be careful when you do it yourself, do not break the buckle.

The next thing is to remove the wiring harness, pay attention to remember the original position of the wiring harness and the corresponding interface, don't dismantle when it's cool, and when you install it, it's forced.

The interior is basically dismantled, so that the hook can reach the depression, and it is generally OK to find a special iron fixing bracket to fix the door to ensure that it will not move back and forth during the repair process.

Then the hook extends to the opposite side of the depression and presses evenly, and the eye uses the light of the light plate to stare at the changes of the depression surface in real time.

The towel in the picture is used to protect the car door, and the shark skin has focused on repairing the car dent for more than ten years, and has a strict repair process and protection plan to ensure that the car will not be damaged twice during the repair process.

After the <> is reached a certain level, it is used to hammer and the special wooden pen (the pen in the picture is the sandalwood characteristic of India, which will not hurt the paint) back and forth until the depression is integrated into the paint.

<> is now basically indented and invisible to the naked eye, but the standard has not yet been met (shark skin has its own set of internal quality inspection standards, leading the industry).

<> the final construction result, are you still satisfied?

The method of repairing the door depression: 1. You can use the bridge suction rod, which can absorb the sol gasket pasted by the owner, and then twist the screw cap until it is pulled to the recess and flattened, so that the force will be more uniform; 2. Go to a professional maintenance shop for light sheet metal, use a suction cup to suck out the concave position, then use the hook to reach into the back of the concave area, slowly eject it out, and finally use a rubber hammer to deal with the protruding part.

The body is dented, and if the paint is not removed, it can be said to be a "blessing in misfortune". Because the paint is not damaged, the body dent can be repaired without traces. Compared with sheet metal painting, dent and traceless repair has the following advantages:

1. Depression and traceless repair** cheaper;

2. The time taken to repair the depression without traces is shorter;

3. The original paint can be retained by the repair of the depression without traces.

Although the advantages are outstanding, the dent and scarless repair is not something that can be done just by thinking about it, and there is also a point mentioned earlier, that is, the paint is not damaged. In addition, if the paint on the recessed part has been repainted, or if it is very close to the edge of the body sheet metal, and the rear fender of some models is a double-layer design, these are not suitable for the dent without trace repair technology.

How to repair the dent without a trace?

1. At present, the most common dent without trace repair is the use of a variety of hooks of different specifications and a leveling hammer, the tool may not be important, for the technician's repair process is very tested.

2. With the help of the hook to reach into the back of the depression area, and then slowly eject out, if the depression position is not convenient to operate, you may need to remove the corresponding parts of the body parts.

3. Then use the leveling hammer to continuously and gently tap the protruding part, which will make the dent disappear as much as possible.

4. Another method is to use hot melt glue to pull out the depression, but the headache of this method is that it is easy to leave residual glue, and you have to do a good job of removing the glue. After the depression is pulled out, the paint is slowly restored with a leveling hammer, just like the first method.

Owners with strong hands-on ability are estimated to be unable to hold themselves. Although there are indeed many dent repair tools to buy online, most of the results of do-it-yourself repair are not as good as those of professionals, so you must think twice before doing it yourself.

If the indentation is very small, try using dry ice. Wear anti-freeze protective gloves and place dry ice directly on the dents, which will heal on their own after about 30-40 seconds. If the dent is slightly larger, it can be repaired with the help of a tool.

When you usually drive, you will inevitably encounter bumps and bumps. It won't be long before the new car will have scars. It is normal for doors to droop.

Although this dent is not obvious from a distance, it will still affect the aesthetics of the vehicle when viewed up close. What if the door is a little recessed? Let's take a look at how to fix a recessed door.

As long as the paint does not fall off and the depth of the depression is not very deep, it can be repaired with professional tools, and the body can be restored to its previous state as much as possible, without the need for sheet metal and painting. I believe that many car owners will breathe a sigh of relief. After all, the ** and time consumption of sheet metal painting are quite exaggerated.

We can buy a set of dent repair tools online. It's not expensive, there are dozens of dollars. First clean the dented part, then put the special glue into the glue gun, plug it in, and preheat it for about seven minutes.

Then choose a suitable spacer. The larger the depression, pay attention to the larger the spacer, the larger the spacer, the greater the traction. Then use an applicator to evenly apply the sol to the gasket, quickly stick to the depression, and press gently until the special glue is fixed and released.

Align the hole in the middle of the suspension bridge with the fixing washer, place the nut on the washer screw and tighten it, then turn the nut until the depression flattens. At the end of the repair, the tool is removed, alcohol is sprayed on the remaining rubber from the body, and finally cleaned with a spatula. If you don't want to do it yourself, then we can give it to an outside repair shop.

They have a technique called dent repair, also known as lightweight metal sheets. However, the dent repair technique is almost the same as what we do ourselves. Suction out the dent with a suction cup, then hook it to the back of the dent and slowly push it out, finally treating the bulge with a rubber hammer.

Automotive dent repair technology is determined by the difficulty and area of the dent repair, as well as the sharpness of the dent**. The sharper the pit, the more difficult it is to repair. ** Over a few hundred dollars.

For example, an egg-shaped depression is generally about 150 yuan. It seems easy to fix the dents on the door. Lara can be found from the back.

In fact, there are big limitations. If the paint damage cannot be repaired, if the dents are near the wheel arches, corners and AB pillars, it is not easy to repair.

Every day when you drive out, there will be a little bump from time to time. It is inevitable that it will touch the door and there will be a little dent, which is related to the beauty of the car. Sometimes it's a small dent that can be fixed on your own.

But some people don't know how to use it, so I will give you a brief introduction to the car. What are the ways to repair door dents? Let's see.

What are the ways to repair door dents? What is the repair of car dents?

The so-called car dent repair is also called micro sheet metal, and friends sometimes call it the car dent non-destructive repair technology. It is different from the traditional sheet metal painting technology, based on the principles of optics, physics and mechanics, and uses the principle of leverage to smooth and repair the dents of different sizes and depths of the body due to various external reasons, and finally restore it to the factory shape.

What are the ways to repair a dented door?

Method 1: Dry ice solution.

Very small dents can be solved with dry ice. Wear antifreeze gloves and place dry ice directly into the indentation. After about thirty or forty seconds, the dent will automatically recover.

Method 2: Tool Solution.

You can choose to buy some tools specifically designed to repair dents, but your friends need to keep in mind that not all dents can be repaired quickly. If the paint is badly damaged or the edges and corners of the dent are too sharp, or even have dead corners, most of them are basically not recommended to repair the dent with this method. In addition to the above two cases, most dents can be quickly repaired with quick retrofits.

To put it simply, as long as the paint is not damaged, the dent is not in the corner of the car, and the dent has no dead end, you can basically repair it yourself, otherwise you need to go to the store to find a professional to repair it.

If you can't pull it without destructive repair, there is no particularly good way, and it is really not possible to cover it with a car flower on the outside, which is also a bit of a personalized decoration.

Car Door Repair Door Dent Steps:

1. It is adsorbed on the object and has a very large tearing force. Then we can use this small suction cup to repair the small depression of the car door, and adsorb the suction cup on the depression.

2. If the depression is larger, you can use a few more. For sharp and large-area depressions, it is recommended to go to the repair shop and call a sheet metal master to repair it.

3. Sheet metal, use a suction cup to suck out the concave position, then extend it into the back of the concave area with the help of a hook, and then slowly eject it out, and finally use a rubber hammer to treat the protruding part, which is similar to the effect of do-it-yourself.

There are probably two general repair methods for car dent repair.

Tool Repair Pry up the depression with a lever repair tool and knock it out point by point with a leveling pen. To sum up, pry up and knock flat repeatedly until the hollow part of the body recovers.

Lever repair is characterized by a good repair effect, and can even arrange the orange peel of the original car (depending on the technician's technique).

Pull out the depression with a pull-out repair tool, and then use a leveling pen to knock it out point by point. To sum up, pry up and knock flat repeatedly until the hollow part of the body recovers.

Pull-out repair is characterized by the simplicity of repair, and ordinary people can also operate and repair as long as they have tools.

Insert the hot melt glue stick from behind the applicator and let the glue stick in completely. Plug the applicator into an electrical outlet, set the temperature of the applicator to the highest, preheat it for a few minutes, and let the hot melt adhesive melt thoroughly. Then select the appropriate traction gasket according to the diameter of the dent, pull the trigger of the glue gun, and coat the traction gasket with melted glue.

Stick the traction gasket coated with hot melt adhesive in different positions according to the different force points, and gently press it with your hands.
