Brief analysis on the development situation and trend of powder metallurgy industry in china

Nov 03, 2022

Powder metallurgy refers to the process technology of making metal powder or using metal powder (or mixture of metal powder and non-metallic powder) as raw material to make metal materials, composite materials and various types of products. It is a multidisciplinary comprehensive technology, involving chemical engineering, metallurgy, material preparation, thermal engineering, machinery, automatic control and other disciplines. The process of Qinhuangdao Zhongwei precision powder metallurgy includes four steps: powder making, forming, sintering and post-treatment.

Powder metallurgy technology has a series of advantages, such as energy saving, material saving, excellent performance, high precision, good stability, etc. It is suitable for mass production. Due to the difference from ordinary process, powder metallurgy has unique chemical composition and mechanical and physical properties, which can not be obtained by traditional casting methods. Powder metallurgy technology can be directly made into porous, semi dense or fully dense materials and products, which is a less cutting process. In addition, some materials and complex parts that cannot be prepared by traditional casting methods and machining methods can also be manufactured by powder metallurgy technology. Therefore, powder metallurgy technology has attracted much attention in the industry.

In recent years, the powder metallurgy industry has developed rapidly, especially in the automotive industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, engineering machinery, electronic appliances and high-tech industries, which has brought great development opportunities for the powder metallurgy industry. At this stage, powder metallurgy products are mainly used in industries such as automobiles, household appliances, electric tools, motorcycles, agricultural machinery and construction machinery. The development of downstream industries will drive the development of upstream industries, and the capacity of the entire industry is constantly expanding.

Qinhuangdao Zhongwei Precision From the perspective of the global powder metallurgy mechanical parts industry, the largest sales market of powder metallurgy parts is the automobile industry. At the same time, this field is also the market with the highest requirements for the technology and quality of powder metallurgy parts. In Europe, Japan and other industrial developed countries, the demand for powder metallurgy parts in the automobile industry accounts for about 90% of the powder metallurgy market, and the demand for powder metallurgy parts in North America accounts for more than 80% of the powder metallurgy market. From the perspective of China's powder metallurgy machine parts industry, the main market of the powder metallurgy parts industry has gradually evolved from the refrigerator compressor industry, the air conditioning compressor industry, and the motorcycle industry to the automobile industry.

According to the data of Qinhuangdao Zhongwei Precision, the current domestic powder metallurgy market scale is 6.4 billion yuan, including about 4 billion yuan for automobile powder metallurgy parts; With the wide application of automobile powder metallurgy products, assuming that China's automobile sales keep a 5% growth rate, the single vehicle use of automobile powder metallurgy parts will reach 15kg. It is estimated that China's automobile powder metallurgy market capacity is expected to reach 14 billion yuan in 2020. The average weight of PM parts produced by European and American automobile companies is about 20kg per vehicle; On average, about 9kg powder metallurgy parts are used for each car produced by Japan Automobile Company; However, the average powder metallurgy parts used in China's automobiles are only about 5kg. China's powder metallurgy industry has a large space for expansion in the future. With the further growth of automobile production and sales in the Chinese market and the increase in the use of single vehicle of automobile powder metallurgy parts, the automobile powder metallurgy market is expected to usher in a relatively rapid development.
