The car bumper is a safety device that absorbs the outside shock and protects the front and rear of the body. Twenty years ago, before and after the car bumper is mainly metal materials, with a thickness of 3 mm or more steel plate stamping into U-shaped steel, surface treatment chrome, and frame longitudinals riveting or welding together, and the body has a The larger gap is like an attached part. With the development of the automobile industry, car bumpers as an important safety device is also on the road to innovation.
Today's car front and rear bumper in addition to maintaining the original protection, but also the pursuit of harmony and unity with the body shape, the pursuit of their own lightweight. In order to achieve this purpose, the car before and after the bumper with the use of plastic, known as the plastic bumper. Plastic bumper is composed of three parts: outer plate, cushioning material and beam. Wherein the outer plate and the cushioning material are made of plastic, and the crossbeam is stamped with a cold-rolled sheet having a thickness of about 1.5 mm to form a U-shaped groove; the outer plate and the cushioning material are attached to the cross beam and the beam is connected with the frame girders, Remove it. The plastic used in this plastic bumper is made of injection molding by using both polyester and polypropylene. There is also a foreign called polycarbonate plastic, infiltration alloy composition, the use of alloy injection molding method, the processing of the bumper not only has a high strength of the rigid, but also has the advantages of welding, and coating performance, The amount spent on the car more and more. Plastic bumper with strength, rigidity and decorative, from the security point of view, the car collision can play a buffer role, to protect the front and rear body, from the appearance point of view, can be naturally combined with the body in one, One, has a good decorative, decorative car as an important part of the appearance.
