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 high pressure and solidifying under pressure to obtain castings.

The precision and surface quality of aluminum die casting manufacturers are higher than other casting methods, can die casting thin wall parts or inlays with complex shapes, high strength and hardness, high productivity, but the equipment investment is large, it is not appropriate to carry out large margin cutting and heat treatment due to the high speed of die casting, the type of gas is difficult to discharge in time. The variety is limited because of the high speed and high temperature erosion of the liquid flow, the life of the press type is very low.

At present, die casting has been widely used in cars, tractors, instruments and weapons. Die casting can be divided into black metal die casting and non-ferrous metal die casting, although collectively known as 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 attributed to liquid, but its activity is easy to oxidize, poor fluidity is difficult to form, For complex parts, it is difficult to exhaust.

The variety of products of aluminum die casting manufacturers is diversified, including cars, 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 ability, the variety and use of die casting products 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 operation in 1914, it has been rapidly developed with the development of the car industry and the invention of cold chamber die-casting machine. Die-cast aluminum alloy is divided into two types according to its performance: medium and low strength (such as China's Y102) and high strength (such as China's Y112). At present, the die-cast aluminum alloy used in industry mainly has the following series: AlSi, Al-Mg, Al-Si-Cu, Al-Si-Mg, Al-Si-Cu-Mg, Al-Zn, etc.
