Relatively low price: For car companies, it is also very important to reduce the production cost of cars, so many car companies choose to use plastic bumpers, which can invest in the research and development of other components to provide better services for consumers.

The price is relatively low and economical.Considering that the use of plastic car bumpers can save the cost of manufacturing, and the funds can be used in work such as material research and development to improve the performance of the whole vehicle. In addition, it has strong plasticity, which is convenient for design and production.

Car bumper is a decorative device installed at the front and rear of the car, which can absorb and relieve external shocks and protect the safety of the body and passengers. Many years ago, car bumpers were mainly made of metal materials, and the surface was plated with a layer of chrome. The U-channel steel is riveted together with the longitudinal beam of the frame, which plays a protective role.

The lighter the quality of the plastic bumper, the lighter the quality of the car, the more ideal the fuel consumption, and the better the braking effect; the plastic bumper also has good insulation, anti-corrosion, aging resistance, wear resistance, scrubbrush resistance, waterproof, and in the event of a slight collision, it can also automatically recover according to its own elasticity.

Plastic bumpers can not only save manufacturing costs, but also have lower requirements for the industrial level and are easier to produce. Therefore, after the cost of car manufacturing is controlled, the price of the final product to consumers will also be more reasonable, which must correspond. Of course, in addition to plastic bumpers, some top sports cars will also use a large number of carbon fiber materials.

At both ends of the bumper, there are two bumper cards, in addition to some bumper covers, such as ventilation grilles and traction covers.

The plastic bumper of a general car is composed of three parts: outer plate, cushioning material and beam. Among them, the outer plate and buffer material are made of plastic, and the crossbeam is stamped into a U-shaped groove with cold-rolled thin plate; the outer plate and buffer material are attached to the crossbeam.

Under normal circumstances, the bumper maintenance is carried out with the car. During the maintenance of the vehicle, the bumper can be overhauled. If there is a problem, try to focus on repair. If the exercise surface is really large, it can be replaced directly. Compared with repair, the price is relatively higher.

Nowadays, the front and rear bumpers of cars are made of plastic. The plastic bumpers of ordinary cars are composed of three parts: outer plate, cushioning material and crossbeam. Among them, the outer plate and cushioning material are made of plastic, and the crossbeam is stamped with cold-rolled thin plate to form a U-shaped groove. The outer plate and buffer material are attached to the crossbeam, and the shape is more harmonious and unified with the car body, and lighter.

And the bumpers of Volkswagen's Audi 100, Golf, Shanghai's Santana, Tianjin's Charley and other models of cars are made of polypropylene materials and injection molding.
