Magnesium alloy injection molding- another way of auto lightweight
The injection forming technology of magnesium alloys constantly improve and its application in automobile parts
manufacturing enterprise, is bound to bring a new revolution for the automotive lightweight, is another way after
the injection molding of aluminum alloy.
Magnesium is the lightest metal elements in the nature, usually exsists as magnesium alloy with other metals. Magnesium
has been paid high attention because of the characteristics of high strength and light weight. Beginning in the 1990's
magnesium alloy entered a rapid development period, was applied in a lot of industries, such as automotive industry,
electronic industry, medical equipment, etc.
China has a rich resource of magnesite, ranked second, just behind the United States, which provides a reliable source of
raw materials or the development of China's magnesium alloy forming. In previous years the price of magnesium is pretty
high, magnesium and magnesium alloys on the prices are more expensive than aluminum and aluminum alloy, currently
the magnesium and aluminum prices have nearly equal. In recent years, for the production of magnesium alloy parts
advantage is greater than aluminum alloy, there is great advantage in the cost of raw materials.
Chongqing science and technology research key projects development and industrialization of lightweight automotive
spare parts after acceptance by experts, research and development of magnesium alloy parts can realize auto lightweight, at
the same time to achieve the effect of energy saving. This marks the development of magnesium alloy parts in China has
entered a new stage.
Application of magnesium alloy in automotive industry proportion has a rising trend year by year, this is because on the
one hand, the density of magnesium alloy is small, the same volume of parts is better than aluminum alloy or other
material parts much lighter in weight. Thus in car running to save more energy, reduce fuel consumption. On the other
hand, Magnesium alloy damping noise reduction performance is good, had a higher oscillation consumption coefficients,
so can absorb vibration and noise transmission, its performance is better than that of aluminum alloy in this respect.
The progress of the magnesium alloy parts forming process is also the basic condition of widely applied in automobile
industry. Magnesium alloy parts has entered the advanced powder forming in the direction of semi-solid forming
progress from liquid forming (casting) forming (forging) and solid phase, this is the injection forming of magnesium
alloy, it is a similar to the AIM of aluminum alloy injection molding process.
With modern products constantly updated, the market need to mass production complex shape thin-walled, shock
absorption, noise reduction, high electromagnetic interference shielding and easy machining metal parts of low density. To
meet our cars, electronic communications, laptop computers, tablet PC, digital camera, camera, medical prosthetics
industries such as more and more high request to the product.
The injection forming technology of magnesium alloys constantly improve and its application in automobile parts
manufacturing enterprise, is bound to bring a new revolution for the automotive lightweight, isaluminum alloyinjection
molding. In recent years, to make larger sizes of magnesium alloy parts, used for large automotive parts, such as the
United States, Germany, Italy and Japan powder injection forming process of more developed countries are to develop the
large-scale injection molding machine, not only machines more complete, more careful, and injection pressure are greatly
increased.
