Powder metallurgy products outstanding again in automotive industry
Powder metallurgy is a mechanical structure part manufacturing technology that can produce complex shape parts, which can save material, save energy and save labor. It is very suitable for mass production. Therefore, in the United States and Japan, the automotive powder metallurgy parts and auto workers are developed synchronously. It is reported that more than 1000 kinds of powder metallurgy parts have been used in automobiles.
The use of soft magnetic in the car horn, radio, TV, VCR, micro instruments and magnetic components, brush using automotive starter and generator in the electrical distribution of platinum contacts (contact w), with the automobile tire anti-skid nail, lead-free gasoline engine exhaust valve seat machine, sintered metal diesel oil filter in the engine, heavy truck brake friction materials, DU, DX bearing large automotive application and double metal bearing and is widely used in automobile manufacturing hard alloy cutting tool, measuring tool and die, these products or materials can only be made by powder metallurgy technology.
This can be seen, without these powder metallurgy products and materials, today's automotive industry is what it is, it is self-evident. At the same time, powder metallurgy is an advanced metal forming technology, metal and other high-tech powder by pressing molding, sintering and subsequent processing of the necessary mechanical parts and metal products.
Because of its advantages of energy saving, material saving, high efficiency, environmental protection and so on, it has been widely used, and has great market potential and development prospects. In recent years, powder metallurgy is developing very fast, especially the rapid development of automobile industry, metal industry, machinery manufacturing, aerospace, instrumentation, hardware tools, construction machinery, electronic appliances and high-tech industries, brought a rare development opportunity and huge market space for powder metallurgy industry. At the same time, the technical level of the industry is also raised higher requirements.
