The development of automobile powder metallurgy molding has faced new challenges

Powder metallurgy is a manufacturing technology for mechanical structural parts, which can manufacture parts with complex shapes, save materials, energy and labor, and is very suitable for large-scale production. Therefore, in the United States and Japan, automobile P/M parts and automobile industry are developing at the same time. It is understood that there are more than 1000 kinds of automobile P/M parts.

Soft and hard magnetic components used in automobile horns, radios, mini TVs, recorders, instruments and meters, electric brushes used in automobile starters and generators, platinum contacts (w contacts) in power distributors, anti slip nails installed in automobile tires, exhaust valve seats of unleaded gasoline engines, sintered metal oil filters in diesel engines, friction materials for heavy truck brakes widely used in automobiles, DU DX bearings and bimetallic bearing shells, as well as cemented carbide tools, measuring tools and molds widely used in automobile manufacturing. These products or materials can only be manufactured by powder metallurgy technology. It can be seen that without these powder metallurgy products and materials, the development of the automobile industry will never reach the current level.

At present, powder metallurgy has been recognized as a green and sustainable manufacturing technology by the industry. Powder metallurgy usually produces finished parts after sintering, which can be packaged and delivered. In most cases, the cutting oil used to process powder metallurgy products is negligible, and the toxic pollutants released by pollution sources such as cooling water are also few. Compared with other manufacturing processes, the powder metallurgy products/parts industry has little harm to the environment.

However, compared with western developed countries, the application of powder metallurgy products in China is far from enough. It is reported that 14 kg of powder metallurgy parts are used per vehicle in Europe, compared with 20 kg in the United States. At present, the number of 6 kg of powder metallurgy parts used per vehicle in China is very small. It can be seen that most domestic enterprises are still basically in the basic processing stage, and their technological innovation ability is poor. It is urgent to improve the product R&D management level and product quality level.

Especially in recent years, with the promulgation of national policies and regulations on energy conservation and emission reduction, automobile safety and environmental protection, as well as the research and development of clean automobiles, environmental protection products will become the main development trend in the future, which brings new challenges to powder metallurgy products as well as huge development opportunities.

Under such an environment, the domestic powder metallurgy enterprises, led by zhongwei Precision Powder Metallurgy, must speed up the upgrading of powder metallurgy technology, make use of the power of science and technology to make our powder metallurgy products meet the market demand, win market share, and always take the lead in the industry. At the same time, we also believe that with the efforts of people from all walks of life, the domestic powder metallurgy industry will develop rapidly in the future, especially the automobile industry, machinery manufacturing Metal industry, aerospace, instrumentation, hardware tools, engineering machinery, electronic appliances and high-tech industries will bring rare development opportunities and huge market space to the powder metallurgy industry.
