Development and Prospect of powder metallurgy in automobile industry in China

From the perspective of the global powder metallurgy machine parts industry, the automotive industry is the largest selling market for PM parts. At the same time, this field is the highest requirement for powder metallurgy parts technology and quality. In Europe and other regions, the demand for powder metallurgy parts in the automotive industry accounts for about 90% of the total powder metallurgy market. From this we can see that the role of PM in the automotive industry is very great.


In recent years, the powder metallurgy industry has developed rapidly, especially in the automotive industry, aviation and machinery manufacturing industries, which have brought great opportunities for development of powder metallurgy. However, China's powder metallurgy products are still far behind developed countries. Foreign countries begin to develop powder forging connecting rods and combined sintered camshafts, etc., and our country has set foot in less, and the level of product research and development is relatively large. Most of the enterprises in China are still at the stage of map processing, with poor technological innovation capability and basically in the stage of imitation innovation. We need to improve the level of product R & D management and product quality. In Europe, the average usage of powder metallurgy parts per vehicle is 14KG, while that of the United States has reached the average 20KG usage. In contrast, the average usage of PM parts per vehicle 6KG is very low in China. Why does that cause this? It is because the powder metallurgy products in our country can not meet the required performance, so the main engine factory can only choose the forging parts and machined parts with higher cost. With the progress of powder metallurgy manufacturing technology, it is believed that the average usage of PM parts will be higher and higher. In recent years, the state has taken strict attention to environmental protection. With the national energy saving and reducing consumption and the automobile safety and environmental protection policies and regulations, and the development of clean cars will become the future development of the key trend, which brings new challenges to powder metallurgy products, but also brings great opportunities for development.


At present, powder metallurgy has been recognized as a green and sustainable manufacturing technology by the industry. In general, powder metallurgy is made of finished parts after sintering, and can be packed and delivered. In most cases, the cutting oil used in the processing of powder metallurgy products is negligible, and the toxic pollutants released by the pollution sources such as cooling water are also very small. Compared with other manufacturing processes, the powder metallurgy parts industry has almost no harm to the environment. Due to the cost of the powder metallurgy products and the advantages of environmental protection, the powder metallurgy market has a very good prospect in the field of automotive industry with the further increase in the sales of China's automobile industry and the improvement of the use of the single car for automobile powder metallurgy parts.
