The front bumper upper body usually consists of the following parts:
Front bumper skin : This is the outer part of the front bumper, usually a plastic material, to absorb the impact of a crash .
Buffer foam : Behind the front bumper skin, there may be a layer of buffer foam used to provide additional protection in the event of a crash .
radiators : In some models, there may also be radiators behind the front bumper to cool the engine and other important components .
