What are the main parts of powder metallurgy used in automobile manufacture?

At present, powder metallurgy has been recognized as a green and sustainable manufacturing technology. Powder metallurgy has sustainable function, material sustainability, energy sustainability, equipment sustainability, environmental sustainability, sustainable employment, sustainable value advantages and so on.

The development and present situation of the production of the powder metallurgy auto parts in guangdong province. The powder metallurgy parts used in auto manufacturing are mainly the sintered metal oil bearing and the structure parts of powder metallurgy. The former is mainly produced by 90cu-10sn bronze, while the latter is basically made by iron powder as the basic material. A type of powder metallurgy 64 tooth force extractor drives the powder metallurgy miniature gear, saving about 40% of the cost compared with the parts processed by steel cutting, and the teeth of the powder metallurgy miniature gear do not need subsequent processing. The utility model relates to a synchronous device ring for the manual transmission of a powder metallurgy automobile, which can reduce the cost by 38% compared with the conventional one. A powder metallurgy composite planetary powder metallurgy miniature gear frame, whose ultimate strength is 40% higher than that of cast iron cutting and machining workpiece, and the cost is reduced by more than 35%.

According to the aforesaid new materials, the powder metallurgy parts can not only replace cast iron parts, forged steel parts, cutting and processing workpieces, save labor, materials and energy, reduce production costs, but also reduce the weight of the parts, which is conducive to lightweight automobile. More importantly, the development of the powder metallurgy composite parts, indicating that some parts can only be manufactured with powder metallurgy technology, has important technical and economic significance.
