Is it good to deal with the plastic dent in the front bumper of the car?

Automobile plastic bumper dent repair method repair method 1: with hot water most of the front and rear bumpers of family cars on the market are cast with special plastic materials, boiling water can restore the hollow car body, the reason is also very simple, the plastic will soften when heated, and it can be ejected out as long as it is heated in the part of the concave. Once the depression has returned to its original shape, use the prepared cold water to cool down the area where the hot water has just been poured and let the rubber shrink and recover.

Repair method 2: Although the plasticity of the bumper is strong by using the depression repair tool, sometimes the strength of the expansion of the hot water is far from enough to support the depression repair, so at this time, you need to use external force, and the depression repair tool can just meet your needs. A set of tools on the Internet is only a few dozen dollars, which is still very effective for small depressions, and you can also put it in the car for emergencies after buying.

Repair method three: after unloading, use your hand to top the car bumper in fact, a small depression occurs, the owner can also try to remove the screw of the car, put his hand into the inside of the bumper of the body, and push a top in the back, in fact, it can also be recovered. However, the bumper is dented and there are usually a lot of scratches, so you have to go to a repair shop to repaint.

Extended informationBumpers are used to protect safety, decorate the vehicle, and improve the aerodynamics of the vehicle. From a safety point of view, the car can play a cushioning role in the event of a low-speed collision accident to protect the front and rear bodies. In the event of an accident with a pedestrian, it can play a certain role in protecting pedestrians.

From the appearance, it is decorative and has become an important part of the appearance of the car; At the same time, car bumpers also have a certain aerodynamic effect. At the same time, in order to reduce the injury to the occupants when the car occurs in the side impact accident, the door bumper is usually installed on the car, so as to enhance the anti-collision impact force of the car door. This method is practical and simple, and has little change to the body structure, and has been widely promoted.

As early as 1993, at the Shenzhen International Automobile Exhibition, the Honda Accord exhibited a part of the door to expose the door bumper to the audience to show its good safety performance. The installation of door bumper is to place several high-strength steel beams horizontally or obliquely in the door panel of each door, which plays the role of the front and rear bumpers, so that the whole car has bumpers "escorted" before and after, forming a "copper wall and iron wall", so that the car occupants have a maximum safety area. Of course, installing such door bumpers will undoubtedly increase some costs for car manufacturers, but for the occupants of the sedan, safety and security will increase a lot!

The front bumper depression of the car is generally plastic, scalded with boiling water or baked in the oven. You can top it from the inside, and then you need to spray paint.

So, in the end, what about the car bumper dent repair, and if you go to a 4S shop or auto repair shop to deal with it, how much does it cost to repair the front bumper concave hit.

When the bumper of the car is dented, we can use the principle of plastic softening when exposed to heat, and heat the part of the depression with hot water to eject it. But this step will take a long time, after all, the plastic needs to be heated to a certain extent before it begins to soften. At this time, we can cooperate with some depression repair tools to deal with it, so as to improve the efficiency of repairing depressions.

Of course, after the depression is restored, we also need to use cold water to cool it down, so as to play a role in shrinkage recovery. However, in addition to restoring the depression of the bumper, we also need to check the car equipment (such as car image and radar), and if there is an abnormal abnormality, it is natural that it needs to be repaired or replaced in time. Of course, for some small partners with handicap parties, it is best to hand it over to the 4S shop or a nearby auto repair shop for repair, as for how much the front bumper is repaired, about 200 yuan can be handled.

But usually, you will be sprayed with a coat of paint after the restoration, so it adds up to about 500 yuan.

The bumper is made of plastic, and you can use a hot blow gun, and after blowing it hot, press it back with your hand.

The heat gun is heated and ejected from the inside, and then the putty is scraped and painted. Generally, such a bar 4S is only replaced, not repaired. The paint shop outside can be repaired.

1. First of all, you need to prepare the tools needed to repair the depression of the car bumper, which are to change the cone and heat the heater.

2. Next, take a soft blanket out, spread it on the ground, and put the bumper directly on the ground It is easy to be scratched by some particles on the ground, so you need to put the damaged bumper on it, so that the bumper will not be scratched and avoid secondary damage to the bumper.

3. Then visually inspect the range of the depression, have a rough number in mind, and then touch the depression with your hand, repeat it several times to determine the final damage range, and then make a reasonable repair plan.

4. Take out the heating heater, then turn on the power supply, turn on the heating heater, aim at the range of the depression, keep moving with your hands, do not blow in one place, so that the bumper depression can be heated evenly, and there is one point that you need to pay attention to, the distance between the heating heater and the bumper must be controlled between 10 and 15cm, not too close or too far, too close is easy to hurt the bumper, too far is not enough heat.

5. After the heating heater blows for a period of time, turn it off, put it aside, and then take out a word to change the cone, press the depression back from the inside of the bumper, what we observe inside the bumper is a bulge, what we need to do is to press the bulge flat, pay attention as quickly as possible, do not wait for the bumper depression to be cold, and then press, it will be very laborious, and it will also lower the bumper to press out the traces, affecting the appearance.

6. After leveling, we return to the bumper depression, touch it repeatedly with our hands, feel whether it is flat, if there is a small depression, and then simply make up for it, until the surface of the bumper is flat, and the repaired bumper should be placed on the shelf, so that the whole depression repair process is completed.

Can be fixed. You can use hot water because the bumper is made of plastic, which softens when heated. Using an electric gun or solar energy is more convenient, stable and faster than using boiling water.

With special repair tools, sometimes the strength or heat of the hot water expansion is far from enough to support and repair the depression, so external force is needed at this time.

Actually, the reason here is very simple. Because the bumper is plastic, it softens when heated, so simply pour hot water into the recess of the rear bumper, then put your hand into the bumper and push it back hard to cope with the general dentation.

2.In fact, when you walk into a garage, you will find that they generally do not use boiling water to repair bumper hollows, but more often use electric guns or solar energy to heat and repair. Compared to solutions that use boiling water, the latter two methods are more convenient, more stable at temperature, and faster.

But the principle is the same. Still no problem.

3.Although the bumper is highly malleable with special repair tools, sometimes the strength or heat of hot water expansion is far from enough to support and repair the dent, so at this time external force is needed, and the dent repair tool can meet your needs.
