Application of aluminum die castings

Aluminum die castings will also have different names in different places. The main ones will include aluminum die-casting parts, die-cast aluminum parts, die-cast aluminum parts, die-cast aluminum, aluminum die castings, and aluminum alloy die-cast parts. Because metal aluminum and aluminum alloys have relatively good fluidity and plasticity, and because the casting process is cast in a pressure die casting machine, the aluminum die casting can also make various complicated shapes.

 

Aluminum die castings can also be made with relatively high precision and finish, which can also reduce the amount of mechanical processing of castings and the casting allowance of metal aluminum or aluminum alloy. When actual processing is performed, not only electricity and metal materials are saved. It also greatly saves labor costs; and it also has excellent thermal conductivity for aluminum and its aluminum alloys, a small specific gravity and high processability.

 

Aluminum die castings will also be widely used in various industries such as automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and building decoration.

 

And the process of aluminum die casting will include annealing, normalizing, quenching and tempering, respectively. These four processes will be called "four fires" in die casting. When they are die-cast, quenching and The relationship between tempering is very close and both are indispensable. And when annealing the workpiece for heating, when heating to the appropriate temperature, according to the selected material is not the same, for the die casting should be slowly cooled, which will also reach the internal metal near the balance of the organization .

 

The quenching process of aluminum die castings heats the workpiece and quickly cools the water or other quenching medium such as inorganic salt solution. After this process, the steel parts produced will also be hardened. Will make steel pieces brittle. In order to reduce the brittleness of the steel parts, the steel parts of the quenched fingers are also placed at a temperature higher than 650 degrees Celsius above normal temperature for a long period of time.
