Application of powder metallurgy technology in automobile industry

    At present, the average use of powder metallurgy products per car in Europe is 14kg, Japan is 9kg, and the United States has reached 19.5kg or more. It is expected that it may reach 22kg in the next few years. At present, the average consumption of powder metallurgy products per automobile in China is only 5-6kg. Taking into account the factors of energy saving and emission reduction, domestic enterprises will use more powder metallurgy processes to produce auto parts in the future. Powder metallurgy mold

    The distribution of powder metallurgy parts in automobiles. Among them, there are shock absorber parts, guides, pistons and low valve seats in the automobile chassis; there are ABS sensors, brake pads in the braking system, etc.; pump parts mainly include fuel pumps, oil pumps and key components in transmission pumps; engines There are ducts, seat rings, connecting rods, bearing seats, key components of variable valve timing (VVT) and exhaust pipe supports, etc.; transmissions have parts such as synchronous hubs and planetary gear carriers.

    With the increasing requirements for energy saving and emission reduction of automobiles, in recent years, VVT parts, variable pumps and brake vacuum booster pump parts, these three types of energy-saving and emission-reducing auto parts have been extensively developed and applied.
