Where is the car bumper located?

Location of car bumpers: The bumper at the front of the car is called the front bumper, and the one at the rear is called the rear bumper. Car bumpers are a type of body accessory and are considered wear-prone parts. Bumpers are installed at both the front and rear ends of the car, not only for decorative purposes but more importantly as safety devices that absorb and mitigate external impacts, protecting the car body and ensuring the safety of passengers. Below is an introduction to the structural composition of car bumpers: 1. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping cold-rolled steel sheets about 1.5 mm thick into a U-shaped channel. The outer panel and cushioning material are attached to the crossbeam, which is connected to the frame longitudinal beams with screws, allowing for easy removal. 2. The plastics used for plastic bumpers mainly include polyester-based and polypropylene-based materials, manufactured through injection molding. For example, the bumper of the Peugeot 405 sedan uses polyester-based material and is made by reaction injection molding.
