The surface was chrome plated and riveted or welded with the frame longitudinal beam. There was a large gap with the body. It seemed to be an additional part, which looked very unsightly.

With the development of automobile industry and the extensive application of engineering plastics in automobile industry, automobile bumper, as an important safety device, has also moved towards the road of innovation. At present, in addition to maintaining the original protection function, the front and rear bumpers should also pursue harmony and unity with the body shape and their own lightweight. The front and rear bumpers of cars are made of plastic, which is called plastic bumpers.
