(1) Automotive powder metallurgy parts market development:

Powder metallurgy metal powder as raw materials, through forming, sintering and other processing methods, the manufacture of high-precision, high-strength metal materials, composite materials and various types of products, through less cutting process directly into complex products, can produce parts that are difficult to manufacture with other methods. Compared with traditional melting and casting technology, powder metallurgy process has more advantages in material utilization, energy consumption, shape complexity of production products, etc., and its utilization rate of materials is as high as 95%, which is one of the most dynamic green technologies. According to the statistics of the Powder Metallurgy Professional Association of China Machinery General Parts Industry Association, the market size of China's powder metallurgy industry increased from 12.05 billion yuan in 2014 to 14.32 billion yuan in 2018, with a compound annual growth rate of 3.5%, and is expected to reach 18.28 billion yuan in 2023.

The automotive industry is the main market for structural powder metallurgy parts, accounting for about 60% of the downstream applications of powder metallurgy parts, and is the core driving force to promote the development of powder metallurgy industry. Synchronizer tooth hub is one of the typical applications of powder metallurgy technology in the field of automotive parts production, in addition, powder metallurgy is also used in the engine, transmission system, steering, sensors and other parts of the production of other parts, the main products are listed below:

Powder metallurgy parts have the characteristics of green environmental protection, energy saving, low production cost and high performance, which is in line with the development trend of lightweight and energy saving of automobiles. Due to the late start of China's automobile industry, the current amount of powder metallurgy parts and components in China's automobile industry is relatively small, the average amount of automobile bicycles is 5-6 kg, and the amount of developed countries and regions such as the United States, Europe, Japan is 19.5 kg, 14 kg and 9 kg, respectively. The main reason for the gap is that at present, the overall technical level of China's powder metallurgy industry is relatively low, and more parts and components can not meet the size and performance requirements, and downstream automobile manufacturers can only choose higher-cost forged and machined parts. In the future, with the improvement of powder metallurgy industry technology in China, product quality and performance will gradually improve, and the amount of powder metallurgy parts for automobile bicycles has a large room for improvement. It is expected that by 2024, China's auto powder metallurgy parts market is expected to reach 9.5 billion yuan.
