Aluminum alloy gravity casting refers to the process of aluminum alloy entering the cavity for casting and forming under the action of gravity, also known as gravity casting. In a broad sense, the more common ways of aluminum alloy gravity casting are aluminum alloy sand casting, aluminum alloy metal mold casting, aluminum alloy investment casting, aluminum alloy lost mold casting, etc. In a narrow sense, aluminum alloy gravity casting is actually through the use of gravity and with the help of various casting methods to change the shape of aluminum alloy. Because there are many ways of aluminum alloy casting, in addition to aluminum alloy gravity casting and aluminum alloy mold casting, then what is the difference between the two kinds of casting process

For aluminum alloy gravity casting, there are three main requirements in the use of materials: the dimensional accuracy is relatively fine, and the material wall thickness should be greater than 4mm. Of course, the thickness can be less than 4mm for some of the more demanding local position Settings. In addition, aluminum alloy gravity casting products high degree of freedom, relatively mature, high production efficiency, good solution.

Compared with gravity casting of aluminum alloy, the mechanical properties of aluminum alloy die casting are far inferior to gravity casting of aluminum alloy. Not only that, but there is not enough time for the metal liquid to be absorbed during the casting process, nor can it be treated with the inherent solution. Of course, many people will say that can we increase the casting efficiency by thickening the outer wall of the material. After the experiment, it is found that even if the outer wall of the material is thickened to 10mm, it can not be very good according to the casting task, and the outer wall of the thickening material is not conducive to production, relatively speaking, the casting cost will increase. However, compared with the traditional casting process of aluminum alloy gravity casting, the outstanding advantage of aluminum alloy mold casting is relatively long service life, and the later maintenance is relatively simple.

Gravity casting of aluminum alloy is one of the main methods to obtain the blank of mechanical castings. Although perfect equipment is the key factor to ensure the quality of aluminum alloy products, but the role of mold in the casting process is also very important. Especially for aluminum alloy auto parts manufacturers, whether the precision of the mold is high enough in the casting process, whether the durability of the equipment is high enough will have a very obvious impact on the quality of aluminum alloy auto parts.

In the process of production of aluminum alloy products, aluminum alloy gravity casting with its casting advantage, is gradually accepted by major car and commodity manufacturers, which makes its proportion in the market share is gradually increased, believe in the near future, aluminum alloy gravity casting the development and application of this technology will be further, At the same time, it will show greater use value in more industries.
