Process Flow Of Aluminum Die Casting Manufacturing

The four basic processes of aluminum die casting manufacturing are annealing, normalizing, quenching and tempering. These four processes are called "four fires" in die casting. In the die casting process, the relationship between quenching and tempering is very Close, the two 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 selected material, 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 performance of the material, and it can also be used as a final die-casting for some parts that do not require much. Quenching is to heat the workpiece and then cool it rapidly in quenching media such as water or other inorganic salt solutions. After this process, the produced steel parts will become hard and at the same time make the steel parts brittle. In order to reduce the brittleness of steel parts, the quenched steel parts can be kept at a temperature below 650 degrees Celsius and higher than normal temperature for a long time, and then cooled, which is called tempering. Application of aluminum die castings Aluminum materials and aluminum alloys have good fluidity and plasticity, so various complex shapes and difficult die castings can be made. Castings made of aluminum alloy and metal aluminum have higher precision and surface finish , which greatly reduces the amount of machining of castings, greatly reduces labor intensity, and saves electricity and metal materials at the same time. Because of its high internal and external quality, aluminum die castings are widely used in various industries such as automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, electric power construction, etc. , become the new darling of the die-casting industry.
