Why are auto parts bumpers made of plastic?

Automobile production has been moulded. In addition to the high-strength material used for the body, many auto parts will use materials that are lightweight, corrosion-resistant, easy to process, easy to form, and easy to maintain and replace. This is the case for the front and rear bumpers of the car, and some external parts of the body, such as fenders, may also be made of lightweight materials such as plastic. Of course, some top sports cars will use a large amount of carbon fiber material on the outer body instead of metal material, the purpose is very simple: the body is lighter, the braking is faster and safer, and it is more fuel efficient.

In fact, plastic bumpers have many advantages. For car companies, the direct effect is to save production costs, and not only that, plastic bumpers can also protect the interests of consumers to a certain extent.

Another point is that if you have a slight collision or scratch, the plastic bumper has good elasticity and has a certain impact resistance. That is to say, if there is no small bump or bump, the plastic bumper will It can automatically rebound and repair automatically. Even if the paint is peeled off, it is still better than the indentation. After all, painting is much cheaper than using sheet metal molds for sheet metal repair.

In addition to these, the plastic bumper can also play a role in protecting pedestrians. After all, the rigidity of the car is not borne by the bumper, but mainly depends on the body frame. Because of the material, plastic bumpers are more elastic and better absorb impact force than metal, so we often see pictures such as bicycles smashing bumpers on the Internet. Think carefully, if it is a metal bumper, a tragedy Most likely pedestrians and bicycles. Here we have to understand that bumpers and anti-collision steel beams are not the same thing at all.
