1. Can control manufacturing costs and facilitate design and production

　　Plastic bumpers can not only save manufacturing costs, but also have lower industrial requirements and are easier to produce. Therefore, after the cost of car manufacturing is controlled, the price of the final product in the hands of consumers will be more reasonable, which must be corresponding.

　　Of course, in addition to plastic bumpers, some top sports cars also use a large amount of carbon fiber materials. In fact, the purpose is very simple, mainly to create a lightweight body to improve the acceleration and braking effects of the vehicle.

　　2. Plastic bumpers absorb energy to ensure pedestrian safety as much as possible

　　After all, the rigidity of a car is not borne by the bumper, but mainly depends on the body frame structure. Therefore, in addition to the design and manufacturing costs, plastic insurance can also play a role in protecting pedestrians.

　　Due to their material, plastic bumpers are more elastic and better able to absorb impacts than metal. Therefore, we can often see pictures of bicycles smashing into bumpers on the Internet. If we think about it carefully, if the bumpers were replaced with metal bumpers, the tragedy would probably be pedestrians and bicycles.

　　3. Plastic bumpers are elastic and can avoid minor bumps

　　If there is a slight collision or scratch, the plastic bumper has good elasticity and has certain impact resistance, which means that if there is a small bump, the plastic bumper can automatically rebound and repair itself. . Even if the paint is peeling off, it is better than being dented. After all, spray painting is much cheaper than sheet metal repair.

　　In addition, in some densely populated countries with a large number of cars and very scarce parking spaces, car owners often have to put their cars close together. At this time, the plastic bumper plays a key role. If your car cannot squeeze into the narrow parking space, you can gently push the vehicle in front or behind at a low speed, so that you can "push" the parking space you need. .

　　4. Plastic bumpers have better anti-corrosion effect

　　For automobile bodies, we all know that metal can easily rust when exposed to water and air, which not only affects the appearance, but also poses certain safety risks. But although car bumpers are parts that are easily bumped during daily driving, plastic has good anti-corrosion properties, so we don't need to worry about it.

　　Many people believe that bumpers play an important role in resisting collisions and are directly related to vehicle safety. In fact, the rigidity of a car is not borne by the bumper, but mainly based on the design of the body frame. In other words, the thickness and material of the bumper do not directly determine the safety of the vehicle. So overall, different bumpers may have differences in small bumps, but they are often vulnerable to larger collisions.
