The front bumper is a safety device that absorbs the external impact and protects the front and rear of the body. Twenty years ago, the front and rear bumpers of the car were mainly made of metal materials, and were punched into U-shaped channel steel with a thickness of 3 mm or more. The surface was treated with chrome plating, riveted or welded with the frame rails, and there was a section with the body. The larger gap seems to be an attached component. With the development of the automotive industry, the front bumper has become an important safety device and has also entered the path of innovation. In addition to maintaining the original protective functions, the front and rear bumpers of today's cars are also pursuing harmony and unity with the body shape, and pursuing their own lightweight. In order to achieve this goal, the front and rear bumpers of the car use plastic, which is called plastic bumper. The plastic bumper is composed of three parts: outer plate, cushioning material and beam. The outer plate and the cushioning material are made of plastic, and the beam is stamped into a U-shaped groove by a cold-rolled sheet having a thickness of about 1.5 mm; the outer plate and the cushioning material are attached to the beam, and the beam is coupled with the frame longitudinal beam, and can be attached at any time. Remove it. Plastics used in such plastic bumpers are generally made of two types of polyester and polypropylene materials by injection molding. There is also a kind of plastic called polycarbonate in foreign countries. It is infiltrated into the alloy composition and is alloy injection molding. The processed bumper not only has high strength rigidity, but also has the advantage of being weldable, and the coating performance is good. The use of cars is increasing. The plastic bumper has strength, rigidity and decoration. From the safety point of view, the car can play a buffering role in the event of a collision, and protect the front and rear body. From the appearance, it can be naturally combined with the car body. One body, with good decoration, has become an important part of the decorative car shape.

A device that generates a cushion when a car or driver is under a force.

20 years ago, the front and rear bumpers of the car were mainly made of metal materials, and were punched into U-shaped channel steel with a thickness of 3 mm or more. The surface was treated with chrome plating and riveted or welded with the frame rails. The big gap seems to be an attached part. With the development of the automotive industry, the front bumper has also been on the road to innovation as an important safety device. In addition to maintaining the original protection function, the front and rear bumpers of today's cars must pursue harmony and unity with the shape of the car body, and pursue their own lightweight. In order to achieve this goal, the front and rear bumpers of the car are made of plastic, which is called a plastic bumper.

The front bumper (anti-collision beam), located in most areas in front of and behind the car, is designed to protect the vehicle's safety system from external damage, and they have the ability to reduce the risk of occupants during high-speed impact. More and more are now being designed for pedestrian protection.
