But for a variety of reasons, the final car manufacturers have found a better alternative & ndash; — Plastic bumper. And for the plastic bumper is fiat, ever since the money saving scheme quickly imitated by various auto enterprises.

Car front and rear bumpers is to compare the typical representative, and body external accessories, such as fender, may also be lightweight materials such as plastic. Plastic bumper can not only save the manufacturing cost, and more to the requirement of industrial level is low, more easy to production. So after building cars cost under control, the price of the final product to the consumers' hands will be more reasonable, it must be a corresponding. In addition to the plastic bumper, of course, some of the best sports car will also be a large number of carbon fibre material. Actually purpose is very simple, mainly to create lightweight body, so as to improve the vehicle's acceleration and braking effect. (2) the plastic bumper suction can ensure the safety of pedestrians as much as possible, after all, car is not borne by bumper, rigidity, mainly to see whether the body frame structure, so in addition to the design and the manufacturing cost, plastic insurance can also play a role in protecting pedestrians. Plastic bumper due to material, is more flexible than metal, and the ability to better absorb the impact. So we can often see a bicycle bruised bumper on the net of such images, think carefully, if replaced with metal bumper then tragedy may well be the pedestrians and cyclists.
