Throughout the application process, aluminum casting has unparalleled advantages over other castings. The advantage is that in the new energy of automobiles, its cast aluminum alloy castings have been widely used in the production of automobile industry. The relative density of aluminum castings of aluminum casting manufacturers is relatively small, but the specific strength of pig iron and cast steel is higher. Therefore, the use of aluminum alloy castings under the same load standard can reduce the weight of reasonable layout. Therefore, the aluminum alloy castings of aluminum casting manufacturers have been widely used in the aerospace industry and the manufacture of transmission equipment and transportation machinery.

Aluminum casting has excellent casting effect in the whole operation process of aluminum casting factory. Their products have a low melting point, so they can be widely used in metal materials and their working pressure casting methods, develop the internal quality of castings, and also limit the accuracy, surface smoothness and production output power.

Aluminum casting has a large heat of solidification and vaporization. Under the same standard, the solidification process of lithium bromide solution will continue to be much longer than that of steel castings and pig iron, with good fluidity, which is beneficial to aluminum foundry manufacturers in casting thick walls and reasonable layout.

After the aluminum casting manufacturer pours the high-temperature metal material liquid in the aluminum casting into the mold, the mold of the product will be filled with a lot of steam. The vapor must be immediately and successfully expelled from the mold, and the molding sand can pass the vapor. This property is called breathability. Otherwise, disadvantages such as vent holes and insufficient pouring may be caused. The air permeability of the mold is affected by the sand grain size distribution, clay composition, moisture composition and sand grain compactness.

Aluminum casting manufacturers call the ability of aluminum castings to resist external damage compressive strength. The molding sand must have a sufficiently high compressive strength so that it will not collapse during the entire process of molding design, transportation and assembly, and will not damage the surface of the mold during the casting process. The compressive strength of the molding sand used by aluminum casting manufacturers should not be too high, otherwise the casting will cause defects due to the reduction of air permeability and tolerance.
