Talking about the reason that plastic bumper has become the configuration of most cars

Plastic bumpers cannot be equated with cutting corners

In fact, automobile production started early, and the front and rear bumpers were mainly made of metal materials. However, for various reasons, Fiat became the first automobile manufacturer to use plastic bumpers. Finally, this more economical solution was imitated by other manufacturers. Plastic bumpers not only save manufacturing costs, but also have lower requirements on the industrial level and are easier to produce. Therefore, after the cost of manufacturing the car is controlled, the price of the final product to the consumer is more reasonable. In addition, for the automobile body, the metal is easily rusted when combined with water and air, which not only affects the appearance, but also has certain safety hazards. However, although the car bumper is a component that is easy to bump in everyday driving, the plastic has good corrosion resistance, so there is no need to worry about it.

Modification of metal bumpers does not mean safer

Many people think that the bumper will play an important role in resisting the impact, it is directly related to vehicle safety. In fact, the rigidity of the car is not borne by the bumper. It is mainly determined by the design of the body frame. That is to say, the thickness and material of the bumper cannot directly determine the safety of the vehicle. So in general, different bumpers may have differences in small bumps, but they are often vulnerable to larger collisions.

Many off-road enthusiasts will modify the metal bumper for the car. In fact, the purpose of this is mainly to improve the impact resistance of the car body. However, the negative impact of this modification is also very large. First of all, if you accidentally hit a pedestrian, the consequences of the impact of metal and body can not be imagined. To know that pedestrians have always been a vulnerable group on the domestic road, so as long as they hit a pedestrian, it is equivalent to finding something for themselves. So the huge metal bumper is equivalent to a time bomb, which can be ignited at any time. In addition, the metal parts will increase the weight of the car body, thus affecting the fuel consumption and braking effect. The modification must be rational. Unless your modification is used for professional competition, the industry does not agree with this practice.
