Aluminum casting is a kind of casting which is widely used in industry at present. Its excellent processing characteristics and low processing cost are highly praised by customers. After remelting, a lot of resources and energy are saved during operation. Therefore, the application and development of this material is, to a certain extent, aluminum castings. It is widely used in desulphurization and filtration technology of molten iron and manufacturing technology of thin-walled high-strength iron castings.

Aluminum casting has a series of excellent properties, such as low density, high specific strength and properties, and will be widely used in aviation, aerospace, automobile, machinery and other industries. Especially in the automotive industry, in order to reduce fuel consumption and improve efficiency, it is a long-term development trend to replace steel and cast iron castings with aluminum and nickel alloy castings.

In order to further improve the properties of materials and develop their potential, aluminum alloy materials, especially aluminum matrix composites, can be used to a certain extent. Performance requirements under different operating conditions.

In the casting process, aluminum castings are prone to internal loosening, shrinkage cavity, porosity and other issues. After machining, the surface dense layer is removed and the internal defects are exposed. When the pressure seal test is carried out on the cast aluminum parts with sealing requirements, such as cylinder block, cylinder head, intake manifold, brake valve body, etc., the existence of defective micropores will lead to the leakage of sealing medium. Scrap and these defects are often found after processing through stress testing, leading to severe work hours, raw materials and energy waves.

Most parts of aluminum casting are made of aluminum, so it has high precision and good quality. As long as it works, it can be used for a long time without any problems. However, such castings are not unsupported for long service life and require basic maintenance work. There is no contamination on the surface of aluminum casting. Finish the cleaning work in time and be able to carry out chemical protection. Although thick grease cannot be used directly, some special protective oil can be used to protect it. Please do not wipe with water or soft cloth every day.

All kinds of casting products are widely used in our production. All kinds of casting bring convenience to our life. At the same time, aluminum casting is also an important part of the automotive industry.

Aluminum casting has some advantages that other castings can't match, such as beauty, light weight and so on, which makes it widely favored by users. Especially since the lightweight of automobile, aluminum casting has been widely used in automobile industry. Products made with various brands are widely used, such as auto parts, various household goods, industrial machine parts. It is a very important and urgent task to reduce energy consumption, reduce environmental pollution and save limited resources. Driven by the general trend of lightweight automobile products, it can be predicted that China's light metal casting market will develop greatly in the next 10 years.

In the working process of aluminum die casting, its annealing is mainly to heat the workpiece. When heated to the appropriate temperature, the die casting will be slowly cooled according to the different materials selected. The internal structure of the metal is close to the balance. Normalizing is to heat the workpiece to the appropriate temperature and then cool it in the air. It is mainly used for the cutting function of materials and can also be used for the purpose of material cutting Some parts need not high die casting as the end.

The quenching of aluminum die casting is to heat the workpiece and cool it in water or other inorganic salt solution. After this process, the produced steel will become hard and brittle. In order to reduce the brittleness of steel parts, the quenched steel parts can be placed at a temperature below 650 ℃ higher than normal temperature for a long time, and then cooled, which is called tempering.

The application of aluminum die casting, aluminum material and aluminum alloy have good fluidity and plasticity, so it can make various kinds of die casting parts with complex shape and great difficulty. The castings cast by aluminum alloy and metal aluminum have high precision and surface finish, which greatly reduces the machining amount of casting, reduces the labor intensity, and saves power and metal materials.

Aluminum die casting has 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, power construction, and other industries, becoming a new favorite of the die casting industry.

Due to the good fluidity and plasticity of metal aluminum and aluminum alloy, and the casting process is cast in a pressure die casting machine, aluminum die casting can make a variety of more complex shapes, and also can make higher precision and finish, so as to greatly reduce the mechanical processing capacity of the casting and the casting allowance of metal aluminum or aluminum alloy, which not only saves power and metal Materials, but also save labor costs.
