Why the car bumper is made of plastic?

The vehicle moves through the front and rear movements and steering, so the front and rear bumpers have a higher frequency of scrape and collision.

Let's take a look at why the car bumper is made of plastic.

First, the plastic material has better corrosion resistance and rust resistance.

Since the front and rear bumpers of the car are more susceptible to scrape, bumps and more frequent contact with ground-water and other materials, metal parts are scratched and the primer is leaked. Over time, it is easy to rust and corrode due to moisture. Corrosion resistance and rust resistance are the advantages of plastic parts.

Second, the molding is fast, the cost is low, and the price is low.

1. Low raw material costs: Plastics are much cheaper than metals as raw materials.

2. Low processing cost: the bumper is punched with abrasive tools, molded at one time, with low technical requirements and low processing cost.

Therefore, the selling price is cheaper.

Third, the maintenance is convenient.

The plastic bumper is waterproof, easy to color, easy to paint, and the iron sheet is damaged after being hit and damaged to repair the anti-corrosion welding.

1. Small scratches: Small scratches or deformation, direct paint repair can be done, small scratches even no need to be repaired, in addition to affecting the appearance of nothing else.

2. Big accident: It is more convenient to directly replace the bumper paint with a large accident.

Fourth, flexibility, cushioning the impact force.

As a fast-moving vehicle, safety is especially important when pursuing speed.

1. The early car was very hard, the metal was fully armed, and the fast-moving hard car was like a bullet, which played a protective role for the insiders, but the hard front and rear bumpers were very harmful to the outside world and people. A bad one can hurt a person's life.

2. The design of the current car begins to take into account the preciousness of human life. It is better to damage the car than to hurt the pedestrian. Therefore, the front and rear anti-collision beams and the door anti-collision beam protect the inside of the vehicle, and the front and rear plastic bumpers and some of the installed foam can absorb the impact force and reduce the damage from the outside.

3. In addition, the bumper is only a thin layer of metal, which does not have much protection for the safety of the vehicle. On the contrary, the damage of the metal casing to pedestrians cannot be compared.

In fact, sometimes it is like a human bone. The hard bone is also wrapped with a layer of skin or muscle to cushion the damage that can be caused by the outside world and reduce the impact of the activity.

Therefore, the design and application of the front and rear bumpers should be more forward to the protection of the safety of the people inside the vehicle and reduce the damage caused by external collisions. Therefore, as time goes by, the front and rear bumpers of the car slowly change from metal to plastic.
