Many people question the front bumper foam as an act of cutting corners by Petrol Car manufacturers. Some Petrol Car bumpers are made of steel plates, and some are made of plastic. As a result, various questions are raised and the shady behavior of producers or suppliers is questioned.
Telegraphs made of steel or aluminum alloy are not difficult to process, but compared with plastic, there is indeed a big gap. The front bumper is made of plastic material, produced by 2 sets of equipment, and the guarantee is about 5,000 yuan per day. But the distance between metals can be very large.
At present, Geely Car are entering the era of lightweighting. The future is not only a stage of lightweighting plastics, but also future development trends, including laser welding, aluminum foam, etc.
Foam on the front bumper of a Petrol Car is a very simple problem. What works between telegraph and conflict girders is the protection of pedestrians. The problem is that some domestic car dealers use too much membership fees when supplying cars, and the product performance cannot meet our requirements. This material is a fatal problem.
With the development of the Petrol Car industry, the emphasis on Geely Car has gradually spread from the interior of the vehicle to pedestrians. The foam charging in front of the bumper is also to maximize pedestrian appeal, rather than the rumored corporate rip-off of Geely Car.
The foam is located between the plastic strips of the body and the bumper that connects to the body internally. It mainly uses intermediate materials to absorb the energy of low-speed collisions so that objects do not directly collide with the car body, thereby absorbing some kinetic energy during high repair prices and low-speed collisions. In order to protect pedestrians to a large extent, the use of foam materials can reduce the total weight of the vehicle to a certain extent and achieve the effect of reducing fuel consumption.
However, there are still some people who do not admit that using cheaper foam instead of harder and more expensive metal materials means that Petrol Car companies are stealing materials. But in fact, in regions with advanced Petrol Car technology such as the European Union, legal provisions for priority protection of pedestrians in low-speed driving conflicts have been passed. Moreover, the foam area of some models is usually larger than the bumper, so when the Petrol Car is not completely disassembled, the rear bumper cannot be found at all, which is also the main reason for misunderstanding.
