Automobile dents are repaired. Generally, automobiles are made of aluminum alloy. However, due to the insufficient hardness of aluminum, when the door collides, it is easy to cause serious injuries to people inside the car and dents. The following is the sharing of repair methods for car dents.

Car dent repair 1 1, if it is shallow scratches and stains.

When driving on crowded roads or residential areas, it is inevitable that something will be rubbed, resulting in some shallow scratches on the car body, and some may be some stains. This kind of situation is very common, there is no need to make a big fight. With the help of rubber or toothpaste and essential balm, it is easy to remove.

2. Small depressions in the main body of plastic parts

If you hit other cars or walls at a faster speed, the front bumper is prone to small dents. If it is a plastic part, we can pour boiling water directly on it or bake it with a lighter through aluminum foil paper or a hair dryer, and then push it out with our fingers when it becomes soft.

Hot air blower can achieve the same effect.

3. Depressions formed by the collision of aluminum or metal objects.

The collision has formed a big dent in the car body, which we can handle with the help of the toilet plunger used in the toilet at home. We just need to apply vaseline to the toilet plunger, then pull it out at the dented position and "suck" it out.

Of course, this situation does not apply to all dents. If it is sharp or small, the dent still needs to be handled by a professional car dent repair shop.

Automobile dent repair originated in Germany in the 1940s, and was introduced to Northeast China at the beginning of the century. The repair technology of automobile dents is to decompose automobile dents point by point by using various technical means such as strong magnetism, strong adhesion and optical lever, and repair automobile dents slightly, raise and flatten them, without moving the original car paint. The force of the tool directly acts on the steel plate on the back of the concave paint surface of the car body, which will not damage the paint surface of the car, thus achieving the effect of paint-free.

This is the charm of automobile dent repair technology, because it is fast, has good repair effect and does not damage the car paint, and is deeply loved by car owners, especially in first-and second-tier cities. This method is undoubtedly the best repair method. Get to the point, how to distinguish the repair effect? After all, there are so many car dent repair shops in China, and the experience of the master is different, and the maintenance effect is of course good or bad. What is the best repair effect?

Under the strong light, the naked eye can't see the problem, and the repaired places are evenly arranged with the same paint pattern arrangement direction and spacing.

Car dent repair 2 There should be two common repair methods for car dent repair, which are divided into jacking type and drawing type.

A, drawing type

Insert the hot melt adhesive stick from the back of the glue gun and let the glue stick enter completely. Insert the glue gun into the power socket, adjust the temperature of the glue gun to * high, and preheat it for 3 or 5 minutes to completely melt the hot melt adhesive. Then select the appropriate traction gasket according to the diameter of the dent, pull the trigger of the glue gun, and apply melted glue on the traction gasket.

It's sinking slowly. If there is a protruding part in the drawing, knock it back and forth with a rubber hammer and a special wooden pen until the concave part is mixed with the car paint. If the dent repair is not ideal, this step can be repeated, but it is generally difficult to restore the dent to its original state only by drawing repair technology. Generally, gentle depressions can be repaired by traction. If the above repair process cannot restore the sag to its original state, we need to use the second jacking method to repair it.

Second, the top inclined type

Top repair needs to be carried out from the reverse side of the sheet metal, so for general maintenance, we need to remove the door trim panel, remove the interior trim panel, find the screws fixed on the door panel, and remove the screws. Break the buckle that fixes the door panel, take off the wire harness on the door panel, and fix the door panel with a fixing rod, so that the gap position on the door can be generally used for maintenance. Jack-up repair needs to insert the tool into the car door with a lever tool, and move the tool to find the sunken position and push out the sunken metal sheet gently and evenly until the metal sheet melts into the car paint, and the radian of the car paint is exactly the same.

Knock back and forth with a rubber hammer and a special wooden pen on the convex part of the jacking project until the concave part melts into the car paint.

For some special dents that cannot be repaired by removing the door trim panel, or the dent area is too large, it is necessary to remove the door and the door. First of all, we need to stick adhesive tape on the edge of the door and the edge of the front fender (to prevent the paint of the door and fender from scratching when separating the door), then remove the screws of the door anklet and wrap the anklet with a towel (mainly to prevent the door from shaking back and forth and scratching the paint).

Directly disassemble the wiring harness between the door panel and the car body, then unscrew the screws between the door panel and the car body to separate the door, and put the door on the shelf to fix it, and we can repair it. When the door is removed for maintenance, the maintenance will be more flexible and the maintenance difficulty will be reduced. The repair speed will be faster.

Suggestion: This repair method is common in professional automobile dent repair brand stores, and it is only for professionals' reference. Non-professionals should not try. If your car body has dents, it is recommended to go directly to the local car dent repair shop for construction, and don't drop the paint to avoid depreciation.

Car dent repair 3 How to repair the collision of all-aluminum body?

If the all-aluminum fuselage is hit, there is no way to repair it with sheet metal, and most of the repair methods are total replacement. All-aluminum body is rarely used by cars. Audi a8 adopts all-aluminum body, and some Jaguar models also adopt all-aluminum body. The all-aluminum body is relatively strong and light, but if there is a collision, it will be difficult to repair. All parts of an all-aluminum car body are not connected by welding, but by riveting and bonding. If the car driven by a rider adopts an all-aluminum body design, it must be repaired in a 4s shop after a collision. If you drive an all-aluminum car body, it is recommended to buy car damage insurance.

Some car covers are not made of aluminum, but some parts of the body frame are made of aluminum. Some cars have detachable body panels made of aluminum and non-detachable body panels made of steel. This kind of car is difficult to maintain. If the car you drive is an aluminum body, you must be careful when driving, because the aluminum body is very difficult to maintain and the cost is very high. When driving at ordinary times, you must obey the traffic rules and don't drive hostile cars. If you meet a guy who cuts in line, riders can write down the license plate number and report it directly. Don't drive too fast.
