福建Complete List of Powder Metallurgy Parts Used in Automobile

The age of powder metallurgy and automobile

In the 1970s, powder metallurgy was relatively mature abroad, and it was also the first to enjoy the convenience brought by new technology. Powder metallurgy technology was widely used in mechanical production, with simple process and high utilization rate of materials. The investment in * * * was only in the initial mold design. Once and for all, the field reflecting the advantages of powder metallurgy was the automobile field. Because cars can be mass produced, it fully conforms to the advantages of this technology, as early as in North America, At that time, the weight of each automobile using powder metallurgy parts was about 15 kg, and all of these parts were parts with complex process, which was also an important reason for the rapid mass production of automobiles. After 2005, with the breakthrough of powder metallurgy industry technology, more space was available for the use of automobile parts, and more than 40 kg of parts on a car were manufactured.

Precise and complex auto parts are mainly concentrated in the engine and gearbox, including camshaft bearing cover, camshaft fixing support, connecting rod, crankshaft bearing cover, oil pump gear and rotor, rocker arm support, planetary support, driven sprocket, tensioner support plate, tensioner pulley, timing chain shaft of intermediate shaft, gear and other complex parts, Greatly reduce the cost of raw materials and labor.

Here's why the powder metallurgy industry is inseparable from the automobile industry

Powder metallurgy is a technology that uses metal powder as the basic raw material to produce metal parts through a series of processes, such as pressing, sintering, shaping, etc.

The original powder metallurgy technology was applied to bronze to make bronze oil bearing, while the powder metallurgy parts of * * * early were used in automobile engines. With the development of technology, iron, carbon, uranium, titanium, manganese, tin, wheel, nickel and other materials gradually emerged.

In 1937 and 1938, iron based powder metallurgy oil pump gears were successfully developed. In view of the fact that powder metallurgy oil pump gears save labor, materials and cost less than the gears originally made of cast iron hobbing (the material utilization rate is 36%), a large British automobile company changed all oil pump gears to powder metallurgy gears in 1940. This is a significant progress in the development history of powder metallurgy structural parts. Since then, powder metallurgy structural parts have taken root in the automobile industry.

With the development of powder metallurgy in the past 50 years, it has become an indispensable basic part in automobile manufacturing, mainly including sintered metal oil bearing and powder metallurgy structural parts. The former is mainly bronze production, while the latter is basically made of iron powder as basic raw materials. Since the 1960s, due to the rapid development and improvement of iron powder production technology and quality, the market of powder metallurgy structural parts has expanded rapidly and the output has increased rapidly; However, sintered metal oil bearing accounted for about 60% of the Japanese market in the automobile (including motorcycle) industry until 2008. In 2008, the output of powder metallurgy structural parts in Japan was about 100000 T, and that for automobiles and motorcycles was about 100000 T, accounting for 90% of the total output. It is not difficult to see how closely the interdependence between P/M parts and automobile (including motorcycle) industry is.

In the 1980s, the production and improvement of water atomized iron based powder created conditions for the production of high-density, high-strength and complex shaped parts by powder metallurgy process. The powder forging technology, which was widely valued in the early 1970s, has entered the North American automobile market since the mid 1980s after nearly 15 years of development. The production process of powder metallurgy parts has been promoted to a new height, greatly expanding the share of powder metallurgy parts in the automobile market.

A metal forming process, metal powder injection molding (MIM), appeared in the early 1970s. After more than 30 years of development, it began to be used to produce high-density, high-strength small powder metallurgy parts with complex shapes at the beginning of the 21st century, opening up a new path for the development of automotive parts.

The rise of the automobile industry drives the rise of the powder metallurgy industry. The two are inseparable. Lianyungang Dongmu has mature technology and experience in the production of powder metallurgy auto parts. Now, the acquisition of Shanghai Fuchi is even more powerful. It has always been the * * * of the powder metallurgy industry in China. Now let's make a scientific introduction to the auto parts made with powder metallurgy.

In view of the huge development potential of powder metallurgy parts, which are mostly used in the automobile field, many automobile manufacturing companies have built their own powder metallurgy plants to independently develop and produce their own supporting parts. With the improvement of the application and technology of powder metallurgy, more and more fields are involved, not only focusing on the development of the automobile industry, but also applied to agricultural machinery, medical industry, motorcycle industry, aerospace industry, household appliances, electric field, etc. Automobiles account for about 70% of the current domestic powder metallurgy market, while in Japan, automobiles account for about 90% of the powder metallurgy industry, This shows that the powder metallurgy parts industry and the automobile have a great stake in co-existence and common prosperity.
