The four basic processes in the die-casting aluminum industry are annealing, normalizing, quenching and tempering.
These four processes are called the "four fires" in die-casting. In the die-casting process, quenching and tempering are closely related, and both are indispensable.
It is understood that annealing is to heat the workpiece. When heated to the appropriate temperature, the die-casting is slowly cooled according to the selected materials to achieve a state of near equilibrium of the internal structure of the metal.
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 can also be used as the end of die-casting for some parts with low requirements.
Quenching is to heat and keep the workpiece warm, and then quickly cool it in a quenching medium such as water or other inorganic salt solutions.
After this process, the produced steel parts will become hard, and the steel parts will also become brittle. In order to reduce the brittleness of steel parts, the quenched steel parts can be placed at a temperature higher than room temperature below 650 degrees Celsius for a long time for insulation, and then cooled.
This is called tempering. Application of aluminum die castings Aluminum materials and aluminum alloys have good fluidity and plasticity, so various complex and difficult die castings can be made.
Castings made of aluminum alloys and metal aluminum have high precision and surface finish, which greatly reduces the amount of mechanical processing of castings, greatly reduces labor intensity, and saves electricity and metal materials.
Due to its high internal and external quality, aluminum die castings are widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, electric motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and other industries, becoming the new favorite of the die casting industry.
