Key Powder Metallurgy Pressed Parts

Product Description

Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials.

Powder metallurgy gear is a high-tech product with less chips and no chips. Powder metallurgy gears are difficult to count separately in the whole powder metallurgy parts, but no matter in terms of weight or number of parts, the proportion of powder metallurgy gears in automobiles and motorcycles is far greater than that of powder metallurgy parts in other fields. Therefore, it can be seen from the increase in the proportion of automobiles and motorcycles in the entire powder metallurgy parts that powder metallurgy gears are in a position of rapid development in the entire powder metallurgy parts. According to the characteristics of the parts, gears are structural parts, and the absolute weight of structural parts in the entire iron-based parts is far greater than that of other types of powder metallurgy parts.

Powder metallurgy includes powder making and products. Among them, milling is mainly a metallurgical process, which is consistent with the literal meaning. However, powder metallurgy products often go far beyond the scope of materials and metallurgy, and are often interdisciplinary (materials and metallurgy, machinery and mechanics, etc.) technologies. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, making powder metallurgy product technology a modern comprehensive technology across more disciplines.

my country's powder metallurgy industry has experienced rapid development for nearly 10 years, but there are still gaps with foreign counterparts in the following aspects: (1) There are many enterprises with small scale, and the economic benefits are very different from foreign enterprises. (2) Products are crossed, companies lower prices with each other, and competition is extremely fierce. (3) Most enterprises lack technical support, backward R&D capabilities, and low-grade products, making it difficult to compete with foreign countries. (4) Reinvest in lack and distress. (5) The technological equipment and supporting facilities are backward. (6) The export of products is small and the trade channels are not smooth.

With my country's accession to WTO, the above shortcomings and weaknesses will be improved. This is because after China's accession to WTO, the market will gradually internationalize, and the powder metallurgy market will have opportunities to further expand; at the same time, with the entry of foreign capital and technology, powder metallurgy And related technical level will also be improved and developed. According to the "2013-2017 China Powder Metallurgy Manufacturing Industry Production and Sales Demand Forecast and Transformation and Upgrading Analysis Report", the total output value of China's powder metallurgy parts and oil-impregnated bearings exceeds 5.5 billion yuan, accounting for a small proportion of the global market, and the development space is relatively broad. According to the statistical data of 53 companies from 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, a year-on-year increase of 39.75%; the total profit was 376 million yuan, an increase of one year over the previous year. times. In terms of output value, the powder metallurgy parts industry achieved a total industrial output value of 5.057 billion yuan, of which new product output value was 628 million yuan, and the new product rate (new product output value/gross industrial output value) was 12.37%; industrial sales output value was 4.973 billion yuan, of which export turnover The value of goods is 628 million yuan, and the export rate (export delivery value/industrial sales output value) is 16.62%.

From the perspective of production and sales scale, according to the statistical data of 53 companies from the Powder Metallurgy Professional Association of the China Machinery Association, the output of China's powder metallurgy parts industry in 2010 was 163,600 tons, a year-on-year increase of 39.40%; sales volume was 161,700 tons, a year-on-year increase of 43.15% %.

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

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 opportunities to the powder metallurgy industry. development opportunities and huge market space. In addition, the powder metallurgy industry has been included in China's priority development and foreign investment projects, and its development prospects are very broad.
