Commissioned by the University of research, National Research Institute in disseminating and applying the results, University and the National Institute of cooperative R & D, jointly organized by the national project implementation, universities and research institutes are jointly entered powder metallurgy technology innovation. The European Federation of powder metallurgy industry and society, organized the European powder metallurgy Association, established the research and development of the close collaboration system, is to the multi Nationality Enterprise development.

Asian countries outside of Japan are also being introduced for the United States and Japan, sent technical personnel to foreign countries to accept the education and training, for the growth of the automobile industry to accelerate efforts to. Japan has the comprehensive strength in the research system, technology development, production technology etc..

The advantages in the market oriented development, production management, quality, technology and other aspects of alloy. Has the world's highest levels of technology in terms of lightweight components and manufacturing complex shape parts, but compared with the United States, backward in the basic research of advanced technology, due to the high energy and labour costs. Thus, the cost is high. Compared with Europe and the United States, between the enterprise collaboration technology development rarely, the lack of a common database, new materials market is smaller than that of other countries, in the standard work on lack, in the University of powder metallurgy system research, especially iron system research is drastically reduced.

What are the signs of the rapid development of industrial technology in powder metallurgy?

The rapid development of the technology of powder metallurgy industry, of China's metallurgical industry put forward more requirements, conventional metallurgical techniques with high hardness, low purity, precision and poor shortcomings, can not meet the industry demand, after several years of technical study, released a new powder metallurgy technology more competent industry demand, it is with metal powder or metal powder and metal powder mixture) as the raw material, after forming and sintering, manufacturing metal materials, composite and products of various types of technology.

From time to time through the combination of the introduction of foreign advanced technology and independent innovation development. In recent years, powder metallurgy industry and technology of China are showing a trend of high speed development, industry one of the fastest growing parts of China general machinery industry, every year, the powder metallurgy industry, the output value of 35% speed increments.

The global manufacturing industry is accelerating the transfer to China, the rapid development of automobile industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, construction machinery, electronic appliances and high-tech industries such as, for the powder metallurgy industry brought rare development opportunity and huge market space.

In addition, powder metallurgy industry has been included in the China priority development and encourage foreign investment projects. Therefore the development of powder metallurgy industry is very broad prospects. Traditional metallurgical export high yield, for example to make a gear, the general gear shaper, gear hobbing and other machining to cut off a lot of material, powder metallurgy is not.

At present, the powder metallurgy technology commonly used in the production of porous materials, such as oil lubricated bearings, oil storage. The production efficiency is high, because there is no need for machining complex shape can be produced. For small size parts. Suitable for the production of metal matrix composites, powder metallurgy products, compared with the traditional roasting process, not only reduces the cost of manufacturing process, also a lot of precision.

At home and abroad, there are differences in the main application areas of powder metallurgy products

At present, powder metallurgy parts technology has been widely used in the fields of automobile, household appliances, construction machinery, electric tools, etc. However, there are differences between domestic and foreign powder metallurgy products in the main application areas.

From the developed countries or regions of the powder metallurgy product structure, the automobile industry is the largest industry in the powder metallurgy parts industry. Developed countries and regions of the powder metallurgy parts of about 90% are used in the automotive industry. Because the development of China's auto industry is relatively late, and the industry of home appliances and motorcycles developed earlier in China, the product structure of the powder metallurgy industry in China is different from that in the developed countries. Automotive industry is China's largest powder metallurgy parts market, which accounted for of the powder metallurgy parts market increased from 32% in 2014 to 57.8% in 2005, is still far below the level of the developed countries.

The development of China's automobile industry not only provides a huge market demand for the powder metallurgy industry, but also puts forward higher requirements for the technology and quality of the powder metallurgy industry in China. Powder metallurgy auto parts can promote the automobile lightweight, energy-saving emission reduction, with the promotion of the domestic automobile market of sustainable development and energy saving and environmental protection policy, powder metallurgy auto parts market will also enter the new period of rapid development, powder metallurgy auto parts will become the main direction of development of the powder metallurgy industry.

Comparison of import and export of high end powder metallurgy products

Compared with developed countries, the production scale of China's iron powder plant is small, the layout is scattered, the equipment renewal and self-development capacity is insufficient. Many of China's export of iron are general properties of iron, mainly exported to Japan, Korea, Southeast Asia and Hong Kong and Taiwan, while imports of iron mainly from Japan, Sweden and Canada and other countries, imports is iron quality iron powder and special purpose.

Compared with foreign advanced level, the reduced iron powder in China still has a big gap. This gap is mainly manifested in the following two aspects:

One is the reduced iron powder is not stable physical and chemical properties, such as components, Poisson ratio, liquidity, and elastic aftereffect compression index fluctuation;

Two is the lower end of the reduction of iron powder, high-end powder series varieties, and more dependent on imports.

The MIM powder metallurgy after recent years of development, varieties of iron powder is obviously increased, but still can not catch up with market demand. This has seriously affected and have limited the development of China's high-end powder metallurgy industry and products. This shows that China is a big country in the world, but it is not a powerful country.

Application of powder metallurgy material for iron powder

In powder metallurgy industry, high purity iron powder is dosage is the biggest, the most widely used metal powder, accounting for the powder metallurgy injection with 70% of the amount of powder can be said of high-purity iron powder production technology, scale, variety and quality in a certain extent, reflect the overall development of powder metallurgy industry.

Compared with tiejingfen, regardless of price, market performance, high performance materials, metal powders have the incomparable advantages. Emerging metal materials are made from metal powder, powder metallurgy make its performance has been greatly changed. For example, molten steel and molten iron at high temperature is difficult to mix together, but the two are easy to mix together, and the metal structure will be changed, the more resistant to high temperature, resistance to cold.

At present, the high-purity iron powder production method mainly [reduction method, spraying method, electrolysis and carbonyl]. The reductive method is low cost, large output, low energy consumption, and has porous morphology, irregular, good formability and green strength is high pressure, in the production of auto parts, compressor parts, sintered bearing, electric tool parts and electronic components such as become irreplaceable raw materials, so the reduction method is one of the main production technique of high purity iron, reduced iron powder has been powder metallurgy industry the main raw materials.

Development direction of high performance powder metallurgy products

Since the beginning of this century, China's economic development has led to the rapid development of the powder metallurgy industry, mainly for the production and varieties increased significantly, and has been higher than the growth rate of GDP development.

With the development of market economy, in recent 10 years, in China's iron quality have greatly improved, mainly improve the total iron content in the finished product of iron, further reducing the oxygen, carbon, acid insoluble matter and other harmful impurities, the increase of the compression performance, varieties and grades increased to more than 20.

Industry insiders have suggested, the future in accordance with national standards for the production of the product types and brands, should also gradually increase the alloy powder, pre alloyed powder, easy cutting powder, iron powder, high wear resistance of powder, no segregation of mixed powder and high technology content, high performance iron powder production, in order to meet the needs of the domestic market, and expand exports to Japan, the Middle East, Southeast Asia and other places.

Closely related to the development and production of metallic materials PM

Powder metallurgy industry is a dynamic industry, with the advent of the Internet age, and the degree of integration of the world economy to accelerate, powder metallurgy industry, business activity is showing a trend of globalization, cross-country and inter-regional economic and technical exchange activities have flourished. Powder metallurgy industry has now become a global industry, a powder metallurgy parts may be designed in one country, in another country is industrialized, in two or three countries is produced.

Many are closely related to the development and production of metallic materials powder metallurgy. Powder metallurgy is a metal powder (or mixture of metal powder and nonmetal powder) as raw material, molding and consolidation, the manufacturing process of metallic materials, composite materials and products. Development and production of high-performance metal powder, powder metallurgy materials and products to improve performance, and promote the progress of powder metallurgy technology plays a vital role.
