There are many applications of Aluminum Die Casting around us, so we can often see aluminum die casting. Next, let’s learn about the four basic processes of aluminum die casting.
The four basic processes in the aluminum die casting industry are annealing, normalizing, quenching, and tempering. These four processes are called the "four fires" in die casting. The relationship between quenching and tempering is very important in the die casting process. Close, both are indispensable.
It is understood that annealing is to heat the workpiece. When it is heated to an appropriate temperature, the die-casting is slowly cooled according to the material selected, and the internal structure of the metal is close to equilibrium. Normalizing is to heat the workpiece to a suitable temperature and then cool it in the air. It is mainly used to improve the cutting function of the material, and it can also be used to end die-casting of some parts that are not required. Quenching is to heat and heat the joint building and quickly cool it in a quenching medium such as water or other inorganic salt solutions. After this process, the steel parts produced will become hard and also make the steel parts brittle. To reduce the brittleness of steel parts, the quenched steel parts can be placed at a temperature below 650 degrees Celsius and higher than normal temperature for long-term heat preservation, and then cooled, which is called tempering.
These four processes are quite common in China die casting factory .
