Aluminum casting is due to the large latent heat of condensation to a certain extent. Aluminum casting has outstanding casting functions. Production costs should be reduced from the perspective of planning and technology, such as using one-mold multi-part skills and automation skills to increase production rates, extend mold service life, and use integrated planning to reduce the number of parts.

Pure aluminum and aluminum alloys have outstanding thermal conductivity, and are used in heat exchange equipment used in chemical production, as well as parts that require outstanding thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines., which make it widely loved by users, especially since the lightweight of cars, cast aluminum alloy castings have been used in the car industry Has been widely used.

Because of its low melting point, casting methods such as metal molds and pressure casting are widely used, which can improve the inner quality of its castings, its dimensional accuracy, appearance smoothness, and production power. The requirements for aluminum castings for cars are developed in the direction of thin wall, messy shape, high strength and high quality.. Under the same weight, the condensation process of molten aluminum is much longer than that of cast steel and cast iron at all times.

There are still many problems to be dealt with for aluminum casting to form its large-scale production and satisfy the requirements of lightweight cars.Aluminum casting has some incomparable advantages when used in other castings, such as its beauty, light weight, corrosion resistance, etc. The liquidity is excellent, which is beneficial to casting thin-walled and disorderly structured castings. Aluminum casting has outstanding appearance gloss and excellent corrosion resistance in the atmosphere Four Cylinder Head Manufacturers and water, so it has a wide range of uses in the production of civil utensils.

The density of cast aluminum alloy is lower than that of cast iron and cast steel, but the specific strength is higher. Pure aluminum has outstanding corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings also have certain uses in the chemical industry. Therefore, the selection of aluminum alloy castings under the same load conditions can reduce the weight of the structure. Therefore, in the aviation industry, power machinery and transportation machinery, Aluminum alloy castings are widely used. To get used to this requirement, the casting process should be further optimized and new alloy materials should be developed
