Process Flow of Aluminum Die Casting
Aluminum die-casting is a kind of die-casting parts. It is a mechanical die-casting machine equipped with casting moulds. It pours liquid aluminium or aluminium alloy into the feed port of the die-casting machine. Through die-casting, it can cast aluminium or aluminium alloy parts with limited shape and size. Such parts are usually called aluminium die-casting. Aluminum die-casting has different names in different places, such as aluminium die-casting parts, die-casting aluminium parts, die-casting aluminium parts, die-casting aluminium, aluminium die-casting, aluminium alloy die-casting parts, etc.
Because the metal aluminium and its alloy have good fluidity and plasticity, and the casting process is cast in the pressure die-casting machine, the aluminium die-casting can make all kinds of complicated shapes, and also can make high precision and smoothness, thus greatly reducing the mechanical processing of castings and the casting allowance of metal aluminium or aluminium alloy, not only saving power and metal materials. Material and aluminium alloy have excellent thermal conductivity, small proportion and high machinability; therefore, aluminium die casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, building decoration and other industries.
Aluminum die-casting can be manufactured as aluminum die-casting automotive parts, aluminium die-casting automotive engine tubes, aluminium die-casting engine cylinders, aluminium die-casting gasoline engine cylinder heads, aluminium die-casting valve rocker arms, aluminium die-casting valve supports, aluminium die-casting power parts, aluminium die-casting motor end caps, aluminium die-casting shell, aluminium die-casting pump shell, aluminium die-casting building parts, aluminium die-casting decorative parts, aluminium die-casting guardrail parts. Aluminum die-casting aluminum wheel and other parts.
The four foundations of die-casting aluminum industry are annealing, normalizing, quenching and tempering. These four processes are called "four fires" in die-casting. In the process of die-casting, the relationship between quenching and tempering is very close, and both of them are indispensable.
Annealing is to heat the workpiece. When the workpiece is heated to the appropriate temperature, the die castings are slowly cooled according to the different materials selected, so that 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. Normalizing can also be used to finish die casting for some parts which need less. Quenching is the rapid cooling process in water or other inorganic salt solution after co-construction heating and insulation. Through this process, the steel parts produced will harden and become brittle at the same time. In order to reduce the brittleness of steel parts, quenched steel parts can be placed below 650 degrees Celsius at a temperature higher than normal temperature for a long time, and then cooled, which is called tempering.
The application of aluminium materials and aluminium alloys in aluminium die castings has good fluidity and plasticity, so it is possible to make all kinds of complex and difficult die castings. The castings cast with aluminium alloys and aluminium metals have high accuracy and surface finish, which greatly reduces the mechanical workload of castings, greatly reduces labor intensity, and saves power and metal materials. 。 Because of its high internal and external quality, aluminium die-casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and other industries, becoming a new favorite of the die-casting industry.
