car bumpers are all made of plastic to create a more streamlined, more aesthetically pleasing front. the price is relatively cheap. for pedestrian protection. lighten the car and so on. relatively cheap
for economic considerations, the use of plastic car bumpers can save the cost of manufacturing this link, and use the funds to work such as material research and development to improve the performance of the vehicle. in addition, its plasticity is strong, which is convenient for design and production. for pedestrian protection.
in china's current laws and regulations, there is almost zero protection for pedestrians. however, in european and american countries, pedestrian protection is stipulated by laws and regulations and must be considered. with iron bumpers, injuries to pedestrians' legs will be fatal. therefore, plastic bumpers will become mainstream. lighten the car
the application of plastic materials in automotive assemblies and components such as bumpers makes it possible to achieve the goal of lightweight vehicles. the lightweight of the car is conducive to reducing fuel consumption and environmental protection. from the perspective of use and maintenance, although the plastic bumper is not as crashworthy as the iron one, it is more economical to use. on the car body, the front and rear bumpers are the most vulnerable parts. and if the bumper is made of iron, it will be very troublesome to repair, and the repair of sheet metal parts is more complicated than that of plastic parts.
