The rapid development of industrial technology, China''s metallurgical industry requirements more traditional metallurgy techniques are many drawbacks to too high hardness, low purity, precision and poor, can not meet the demand of the industry, after several years of technology explore, newthe baked powder metallurgy techniques more competent industry needs, it is based on the metal powder (or a mixture of metal powder and nonmetal powder) as a raw material after forming and sintering, the manufacture of metal materials, composite, and various types of products, process technology.
From time to time, the introduction of foreign advanced technology and independent development of innovative combined, in recent years. Powder metallurgy industry and technology has emerged as a trend of rapid development, China General Machine Components Industry, one of the fastest growing industries in the powder metallurgy industry output value annually nationwide rate of 35% increments. Global manufacturing is accelerating the transfer to China, the rapid development of the automotive industry, machinery manufacturing, metal industry, aerospace, instrumentation, hardware tools, construction machinery, electronic appliances and high-tech industries such as powder metallurgy industry has brought a rare development opportunities and a huge market space. In addition, the powder metallurgy industry has been China''s inclusion on the priority to the development and encouragement of foreign investment projects. Therefore, the development prospects of the powder metallurgy industry. Traditional metallurgical system port high-yield, such as the production of gears, general slotting, hobbing machining must cut off a large number of materials, powder metallurgy is not. The powder metallurgy technology commonly used in the production of porous materials, such as oil-bearing self-lubricating bearings, oil could be stored. High production efficiency, because of the machining is not required to produce complex shapes. Used for small size parts. Suitable for the production of metal matrix composites, powder metallurgy products, compared with the traditional roasting process, not only reduce the cost of manufacturing process precision many.
