Energy-saving and emission-reducing automobile parts become an important development direction of powder metallurgy industry

Powder metallurgy is a new type of net near-molding technology, which uses melting, heating, injection and pressing of metal powder to carry out the required mold molding. For some special materials such as refractory metals, refractory metals, high alloy and so on. So what is the important development direction of powder metallurgy industry? Let's take a look at it with Zhongwei Xiaobian.

With the progress of technology and the continuous improvement of the performance of P/M parts, the development speed of P/M structural parts has far exceeded that of sintered metal oil-bearing since 1965. At first, most of the powder metallurgy structural parts used in automobiles were concentrated in the engine and transmission, mainly the parts with complex shape, high density, high strength and high performance. Such as engine connecting rod, camshaft, bushing, gear, gear ring and other parts.

Due to the advantages of powder metallurgy technology such as saving raw materials, light weight, excellent performance and low cost, in addition to engines, transmissions and motor bearings, powder metallurgy parts are now used more and more widely in automobiles, and more parts are used in chassis, body and interior decoration, with a very broad prospect.

At present, there are more than 1000 kinds of powder metallurgy parts used in automobiles. Some insiders pointed out that powder metallurgy structural parts have unique advantages in replacing existing gears, cams, sprockets, castings of various shapes, forgings, machined parts and developing new structural parts.

In recent years, due to the excessive use of high-carbon energy, extreme weather has occurred frequently, which has brought serious disasters to human life. In order to achieve the goal of harmonious coexistence between human beings and nature, we must change the existing way of life, save energy, reduce CO2 emissions, protect the environment, and meet the arrival of the low-carbon era. New energy vehicles are gradually being used. As an important part of new energy vehicles, powder metallurgy parts are also developing towards the goal of energy conservation and emission reduction.
