Information

In recent years, some reports about car bumpers without being bumped have caused widespread heated discussions. People who don't know the truth have "spoken and written" against manufacturers, thinking that plastic bumpers are shoddy without being bumped. Actually, this is a misunderstanding.
The promotion of plastic bumpers stems from a foreign regulation on car safety: cars in low-speed collisions should give priority to pedestrian protection. When a traffic accident occurs, pedestrians are often vulnerable groups, and plastic bumpers can alleviate the impact of vehicles on pedestrians' legs, especially their calves. After years of improvement, the bumper has formed its current structure, which can reduce the degree of injury to pedestrians in the event of an accident.
Metal becomes plastic, but it is safer! When the plastic bumper encounters an impact, the resulting deformation can absorb a certain amount of collision energy. At the same time, the bumper can disperse the force to the energy-absorbing boxes on both sides, then transmit it to the left and right front longitudinal beams, and then transmit it to other structures of the body, and finally resist it by the structural strength of the body, which improves the absorption rate of collision energy.

In addition to the plastic bumper itself, there is also the foam filled between the crash steel beam and the bumper. In fact, this is not the so-called "cutting corners", but the buffer material between the outer plate and the beam. After the foam is installed, the bumper is not easy to break in a low-speed collision, and plays a buffering role, which not only protects pedestrians, but also reduces the loss of car owners.
Because the sense of foam to most people is not very good, some car companies cancel the foam as a filler, and instead weld the energy-absorbing box on the anti-collision steel beam. Since the paint color is the same as the steel beam, it looks a lot "stronger".

If you only use foam behind the bumper, and no impact steel beams, you're really cutting corners!
Compared with metal bumpers, plastic bumpers not only ensure pedestrian safety, but also have the advantages of reducing production costs, easy maintenance, and anti-corrosion.
