Mazda has developed resin materials for auto parts
Japan Mazda company has recently developed resin materials for auto parts that can realize lightweight car body. While maintaining the same strength as the previous materials, thinner parts can be manufactured and the material usage fee can be reduced. The lightest level bumper made of this resin material will be equipped with the front and rear of the new SUV "cx-5", which will be sold after the surface is leveled with a trowel this spring, and will be equipped on new vehicles in succession
this material was jointly developed by Mazda and Japanese polypropylene company, which is engaged in the production and sales of products using polypropylene resin to expand 3D printing technology in medical diagnosis, rapid manufacturing, precision casting and other fields. When it is used on the bumper, the weight can be reduced by about 20%. The bumper is installed at the front and rear of the vehicle, so its weight will have a great impact on the fuel efficiency and driving performance of the vehicle. This kind of resin also needs to have the rigidity that can buffer the collision, the formability that can ensure the flexible design, and the sprayability
in terms of manufacturing process, by reducing the thickness of parts, the cooling time during molding can be shortened. At the same time, by using the design and analysis technology of computer, the fluidity of resin material can be optimized. The molding time of bumper can be changed from about 60 seconds to an AC power adapter, which is suitable for 100 ⑵ 40 volt power supply The use of hydrogen battery is shortened to 30 seconds, only half of the original. Through these measures, the energy consumption required to manufacture resin materials can be greatly reduced
the lightweight bumper is a composite resin material containing two components with different characteristics, polypropylene and rubber, and then forms a double-layer structure according to the required functions on the surface and inside of the bumper substrate. Even though the thickness is thin, the adhesion of the coating film is realized on the surface, 50million cycles are still intact, and the excellent rigidity and collision cushioning are realized inside. Mazda will continue to focus on lightweight to improve the basic performance of cars in the future
