The plastic bumper is composed of three parts: the outer panel, cushioning material, and crossbeam. The outer panel and buffer material are made of plastic, and the crossbeam is stamped with a cold-rolled thin plate with a thickness of about 1.5 millimeters to form a U-shaped groove; The outer panel and cushioning material are attached to the crossbeam, which is connected to the longitudinal beam of the frame by screws and can be removed at any time. This type of plastic bumper uses two types of materials, polyester and polypropylene, and is made by injection molding.

In the event of a collision, the front bumper of the car can absorb some energy, reduce the impact on the body and passengers, and play a buffering role. Meanwhile, the crossbeam of the bumper can withstand impacts from the side, protecting other parts of the vehicle from damage. In addition, the appearance design of the bumper can also beautify the vehicle, improve the aerodynamic characteristics of the vehicle, reduce air resistance, and improve fuel efficiency.
