Bumper is a device that absorbs and mitigates the external impact force and produces a buffer when the vehicle or the driver is in the impact force, and plays a role in protecting people and the car.
In addition to maintaining the original protection function, the front and rear bumpers also pursue harmony and unity with the body modeling, and pursue their own lightweight. At present,
the front and rear bumpers of cars are made of plastic, which is called plastic bumper. The plastic bumper is composed of three parts, such as the outer plate, the buffer material and the beam.
