Aluminum die casting
Aluminum die casting is a pressure casting part, a mechanical die-casting machine that uses a pressure casting machine to fit the mold of a casting. The aluminum or aluminum alloy heated to a liquid is poured into the inlet of the die-casting machine. The die casting machine is die-casting and the shape and size of the mold and size of the mold are cast. The parts usually to be called Aluminum castings.
Aluminum Alloy Characteristics:
Aluminum castings have different methods in different places, such as aluminum die-casting parts, die-casting aluminum parts, die-casting aluminum parts, die-casting aluminum, aluminum castings, aluminum alloy die-casting parts, etc.
Because of the good fluidity and plasticity of the metal aluminum and the aluminum alloy, and the casting process is made in the pressure die-casting machine, the aluminum die casting can make all kinds of more complex shapes, and also make high precision and finish, which greatly reduces the mechanical processing amount of the casting and the aluminum or aluminum alloy. The casting allowance of gold not only saves electric power, metal material, but also greatly saves labor cost, while aluminum and aluminum alloy have excellent thermal conductivity, small proportion and high machinability, and aluminum die casting is widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, and transmission. Mobile machinery manufacturing, precision instruments, landscaping, electric power construction, building decoration and other industries.
Aluminum’s strength, corrosion resistance, and heat dissipating properties offer mechanical designers significant advantages. And our proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for even more applications.

Aluminum Die Casting classification
Aluminum die casting can be made up of aluminum die-casting auto parts, aluminum die-casting automobile engine fittings, aluminum die-casting engine cylinder, aluminum die-casting gasoline engine cylinder head, aluminum die-casting valve rocker arm, aluminum die casting valve support, aluminum die-casting electric fittings, aluminum die casting motor end cover, aluminum die casting shell, aluminum die-casting pump shell, aluminum die-casting building. Accessories, aluminum die casting decorative fittings, aluminum die casting guardrail fittings, aluminum die-casting aluminum wheels and so on.
Stainless steel balls are widely used in surface treatment of non-ferrous metal die castings, casting parts, aluminum profiles, automobile parts, machinery manufacturing, hardware, pump and valve industries. They are mainly concentrated on the surface oxide of the products, burrs on the edges, rough surfaces, sub gloss fruits, leveling and rust removal. The stainless steel ball is commonly called stainless steel wire cutting pill. It is made of drawing, cutting and throwing round and so on. The appearance is bright and no rust, and the round ball (pellet, cylindrical). The hardness of stainless steel ball is moderate, the composition is pure and the coverage is large. Because of its lack of the blowholes and the specialties of the steel shot, it has a longer service life, and the product can completely replace the imported products, and the price is much lower than the imported product, and the cost is saved for the customers. After casting with stainless steel pellet, the surface of the casting is smooth and not rusty, without pickling and other post-processing, which is beneficial to environmental protection. You can choose two different shapes of products: pre polished ball cut balls and unpretreated cut balls.
Aluminum Die Casting Technological process
The four processes in the 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, both are indispensable.
It is understood that annealing is the temperature of the workpiece, when heated to the appropriate temperature, according to the different materials selected, the die casting is slow cooling, which has reached the internal structure of metal close to the balance. Normalizing is the cooling of the workpiece in the air after heating the workpiece to the appropriate temperature. It is mainly used to improve the cutting function of the material and can also be used as an end die-casting for some parts with low needs. Quenching is to heat the workpiece after heating, in water, or by other inorganic salt solution and other quenching medium cooling medium rapidly cooling, through this process, the production of steel will be hardened, and also make the steel brittle. In order to reduce the brittleness of the steel, the quenched steel can be placed below 650 degrees Celsius at a temperature of higher than the normal temperature for a long time, and then cooled, which is called tempering.
Aluminum and aluminum alloys have good fluidity and plasticity in the application of aluminum and aluminum alloy. Therefore, it is possible to make various kinds of complex and difficult die-casting parts. The casting with aluminum alloy and metal aluminum has high precision and surface finish, which greatly reduces the mechanical processing quantity and greatly reduces the casting. Labor intensity, at the same time save power, metal materials. Because of its high internal and external quality, aluminum die casting has been widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, electric power construction, and other industries, and become the new favorite of the die casting industry.
