What is the use of powder metallurgy?

With the development of high-tech industry, the variety and demand of new materials, especially new functional materials, are increasing. Powder metallurgy is one of the new materials. It has a series of advantages, such as significant energy saving, material saving, excellent performance, high product accuracy and good stability. It is not usually suitable for mass production. Powder metallurgy is a process of making metal powders or using metal powders as raw materials, forming and sintering, What is the use of powder metallurgy?

1. Powder metallurgy is mainly applicable to the production and research of spare parts in automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instruments and meters, hardware tools, electronic appliances and other fields, production of related raw materials and accessories, manufacturing of various powder preparation equipment and sintering equipment.

2. In military enterprises, heavy weapons and equipment such as armour piercing shells, torpedoes, aircraft tanks and other brake pairs need to be produced by powder metallurgy technology.

3. It can realize near net formation and automatic batch production, thus effectively reducing the resource and energy consumption of production.

4. It can make full use of ore, tailings, steelmaking sludge, steel rolling scale, and recycling waste metal as raw materials. It is a new technology that can effectively regenerate and comprehensively utilize materials.

Application field broadcast

Powder metallurgy related enterprises are mainly applicable to the production and research of spare parts in automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instrumentation, hardware tools, electronic appliances and other fields, production of related raw materials and accessories, and manufacturing of various powder preparation equipment and sintering equipment. Products include bearings, gears, carbide tools, molds, friction products, etc. In military enterprises, heavy weapons and equipment such as armour piercing shells, torpedoes, aircraft tanks and other brake pairs need to be produced by powder metallurgy technology. Powder metallurgy auto parts have become the largest market in China's powder metallurgy industry in recent years, and about 50% of auto parts are powder metallurgy parts. [2]

(1) Application: (automobile, motorcycle, textile machinery, industrial sewing machine, electric tools, hardware tools, electrical appliances, engineering machinery, etc.) various powder metallurgy (iron copper base) parts.

Broadcast by research department

There are few domestic universities that systematically study powder metallurgy. The Powder Metallurgy Research Institute of Central South University (this research institute is recruiting undergraduates, masters and doctoral candidates in China) is the most famous powder metallurgy research institution in China. Huang Peiyun, the founder of China's powder metallurgy discipline, has been in charge for a long time. The State Key Laboratory of Powder Metallurgy and the National Engineering Testing Center of Powder Metallurgy are also located here. Other well-known institutions include the Powder Metallurgy Research Institute of Beijing University of Science and Technology, the General Institute of Iron and Steel Research, the General Institute of Nonferrous Metals Research in Beijing, Zhuzhou Cemented Carbide Group Co., Ltd. (one of the 156 key projects under the "First Five Year Plan"), Sichuan Zigong Cemented Carbide Co., Ltd. (separated from Zhuzhou), Ganzhou Zhangyuan Tungsten Industry, Ningbo Dongmu, Hangzhou Powder Metallurgy Research Institute, etc. If the research direction of powder metallurgy is expanded, the material colleges and research institutes of major universities in China are more or less involved.

Broadcasting of development prospects

The powder metallurgy industry in China has experienced rapid development for nearly 10 years, but there are still some gaps with the same industry abroad in the following aspects: (1) There are many enterprises with small scale, and the economic benefits differ greatly from those of foreign enterprises. (2) The products are crossed, and the enterprises depress each other's prices. The competition is extremely fierce. (3) Most enterprises lack technical support, backward R&D capability, and low product grade, making it difficult to compete with foreign countries. (4) Lack and trouble of reinvestment. (5) The process equipment and supporting facilities are backward. (6) Product exports are few and trade channels are not smooth.

With China's accession to the WTO, the above shortcomings and weaknesses will be improved. This is because after China's accession to the WTO, the market will gradually internationalize, and the powder metallurgy market will get further expansion opportunities; At the same time, with the entry of foreign capital and technology, powder metallurgy and related technology will also be improved and developed.

According to the data in the 2013-2017 Analysis Report on Production and Marketing Demand Forecast and Transformation and Upgrading of China's Powder Metallurgy Manufacturing Industry, the total output value of China's powder metallurgy parts and oil-bearing exceeds 5.5 billion yuan, accounting for a small proportion of the global market, and has a broad development space. According to the statistics of 53 enterprises by the Powder Metallurgy Professional Association of China Machinery Association, the main business income of China's powder metallurgy parts industry in 2010 was 4.841 billion yuan, up 39.75% year on year; The total profit was 376 million yuan, double that of the previous year. In terms of output value, the powder metallurgy parts industry achieved a total industrial output value of 5.057 billion yuan, including 628 million yuan of new product output value, and the new product rate (new product output value/total industrial output value) was 12.37%; The industrial sales value is 4.973 billion yuan, of which the export delivery value is 628 million yuan, and the export rate (export delivery value/industrial sales value) is 16.62%.

From the perspective of production and sales scale, according to the statistics of 53 enterprises by the Powder Metallurgy Professional Association of China Machinery Association, the output of China's powder metallurgy parts industry in 2010 was 163600 tons, with a year-on-year growth of 39.40%; The sales volume was 161700 tons, up 43.15% year on year.

Through the combination of continuous introduction of foreign advanced technology and independent development and innovation, China's powder metallurgy industry and technology are showing a trend of rapid development. It is one of the fastest growing industries in China's general machinery parts industry. The output value of the national powder metallurgy industry is increasing at a rate of 35% every year.

The global manufacturing industry is accelerating its transfer to China. The rapid development of the automobile industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, engineering machinery, electronic appliances and high-tech industries has brought rare development opportunities and huge market space for the powder metallurgy industry. In addition, the powder metallurgy industry has been listed as a priority development and encouraged foreign investment project in China, with broad prospects for development.

What's the use of powder metallurgy? Today, Zhongwei Precision shares here,. In recent years, powder metallurgy auto parts have become the largest market in China's powder metallurgy industry. About 50% of auto parts are powder metallurgy parts. Some materials and complex parts that cannot be prepared by traditional casting methods and machining methods can also be made by powder metallurgy technology, which has attracted much attention from the industry.
