The characteristics and application of aluminum die casting parts are described briefly

It is understood that pressure casting is referred to as die casting, which is a method of filling the die casting cavity with liquid or semi-liquid metal at a higher speed under the high pressure effect, and condensing under the pressure effect to obtain the casting.

The precision and surface quality of die casting parts are higher than other casting methods, can die casting thin wall parts or inlay parts with chaotic shape, high strength and hardness, high productivity, but the equipment investment is large, it is not suitable for large margin cutting and heat treatment because the die casting speed is extremely high, and the gas in the mold is difficult to discharge in time. The variety is limited because the life of the pressure type is very low under the high speed and high temperature of the liquid flow.

Nowadays, die casting has been widely used in automobile, tractor, instrument and weapon profession. Die casting can be divided into black metal die casting and non-ferrous metal die casting, although the general name of die casting, but the process and equipment are very different, zinc die casting, copper die casting, aluminum die casting, etc., generally speaking, copper die casting is mostly semi-liquid or nearly solid state molding, zinc is pure liquid molding, aluminum is also liquid, but its activity is easy to oxidize, poor fluidity is difficult to form, With structural clutter, it is difficult to exhaust.

The variety of die casting products in China is diversified, including automobiles, motorcycles, communications, home appliances, hardware products, power tools, IT, lighting, escalator steps, toy lights and so on. With the improvement of technical level and product development talent, die casting product varieties and application fields continue to expand, and its die casting equipment, die casting mold and die casting process have undergone great changes.

Since the commercial production of die-cast aluminum alloy was put into production in 1914, it has developed rapidly with the development of the automobile industry and the creation of cold chamber die-casting machines. Aluminum die casting manufacturers are divided into two kinds according to the function of low and medium strength (such as China's Y102) and high strength (such as China's Y112). Now the industrial application of die-cast aluminum alloy mainly has the following series: AlSi, Al-Mg, Al-Si-Cu, Al-Si-Mg, al-Si-Cu-Mg, Al-Zn and so on.
