Modern manufacturers make bumpers, which provide an additional level of safety for both the car and pedestrians. The materials from which these parts are manufactured , endow them with increased strength.
To date, automobile plants, which additionally manufacture spare parts and components, use various modern computer technologies in the production process. Special programs allow you to create and improve many spare parts, including bumpers, which are involved in a virtual crash test before starting the production process . When designing, the possibility of collision with pedestrians is taken into account, therefore both the rear and the front bumper are designed with such a consideration that in an emergency road situation to reduce the level of injury to people.
On the computer monitor screen, a mold drawing is performed, which is necessary for the bumper molding. Currently, several casting technologies are used, with which the front bumper is made (the same as the rear). The most common of them and economically profitable is the method of casting using gas (nitrogen). This technique provides for a uniform distribution of nitrogen over the melt, which allows to obtain a more even and stronger surface of the product.
The main function assigned to the bumper is to provide additional protection for the body of the car from mechanical damage. In the territory of the European Union, the standards regulating the quality of bumpers are applied. In the United States of America and Canada, more stringent standards are applied, which require additional tests, in which the rear and front bumper in high-speed mode contact with the obstacle.
Modern bumpers, in addition to protective functions, must have a beautiful enough appearance and fully fit into the design of the car. This is possible due to the use of various synthetic materials in the manufacturing process. There are cases when bumpers themselves require protection. Very often one can observe a picture in which additional devices are mounted on the bumpers, which protect them during a collision with an obstacle. The front guard of the bumper means quite serious material costs, therefore, modern parking systems are installed on modern models of vehicles. They are aimed at training the driver to make a non-contact parking machine.
At the moment, some Lada cars have a bumper front (Priora), smoothly flowing into the body. In some cases, it enters the composition, in which it is a single whole with a false radiator grille. Automotive designers have developed a module that can soon completely replace the front bumper. It is aimed at absorbing the impact, while it contains lighting equipment, various parts of the cooling system and elements of climate control. Such modules can replace dozens of parts. They are supplied by the manufacturer in a fully assembled state. Their installation is simple enough and does not take a lot of time.
