Repair method 1: use hot water.

At present, most of the front and rear bumpers of family cars on the market are made of special plastic materials. Boiling water can restore the sunken car body, and the reason is simple. Plastic will soften when heated, and it can be sprayed out in the concave part as long as it is heated. Once the depression is restored to its original state, please immediately use the prepared cold water to cool the place that has just been drenched by hot water and let the rubber shrink back.

Repair method 2: use the sag repair tool.

Although the bumper has strong plasticity, sometimes the strength of hot water expansion alone is far from enough to prop up and repair the sag, so at this time, external force is needed, and the sag repair tool can just meet your needs. A set of tools on the internet costs only tens of dollars, which is very effective for small depressions. After you buy it, you can put it in the car for a rainy day.

Repair method 3: After unloading, push by hand.

In fact, there is a small dent in the bumper of the car. The owner can also try to remove a screw from the car, put his hand into the bumper of the car body and push it hard at the back. In fact, it can be redeemed. However, there are usually many scratches in the bumper depression, which need to be repainted in the repair shop.

Extended data

Bumper has the functions of safety protection, vehicle decoration and improving aerodynamic characteristics of vehicles. From the safety point of view, when a car has a low-speed collision accident, it can play a buffering role and protect the front and rear car bodies.

In the event of an accident with pedestrians, it can play a certain role in protecting pedestrians. From the appearance, it is decorative and becomes an important part of decorating the appearance of cars; At the same time, the automobile bumper also has a certain aerodynamic effect.

At the same time, in order to reduce the injury to passengers in side collision accidents, door bumpers are usually installed on cars to enhance the anti-collision impact of doors. This method is practical and simple, and has little change to human body structure, so it has been widely used.

As early as 1993 Shenzhen International Automobile Exhibition, Honda Accord, which participated in the exhibition, cut a part of a door to show the bumper of the door to the audience to show its good safety performance.

Installing door bumpers means placing several high-strength steel beams horizontally or obliquely in the door panel of each door to play the role of bumpers at the front and rear of the car, so that the whole car has bumpers to "protect the car" and form a "iron wall", so that the occupants in the car have a maximum safety area.

Of course, installing this kind of door bumper will undoubtedly increase some costs for automobile manufacturers, but for the occupants in the car, the safety guarantee will increase a lot.
