Because the aluminum casting has the advantages of accurate size and smooth surface, it can be used directly after processing, which not only improves the utilization rate of metal, but also reduces a lot of processing equipment and casting price. Aluminum casting manufacturers use combination die casting and other metal or non-metal materials, which can save assembly time and metal. Although aluminum casting has many advantages, it also has some disadvantages that need to be solved. For example, due to the fast filling speed and unstable state of the liquid metal cavity, the general die casting method is adopted. It is difficult to die cast the complex internal concave castings because of the porosity and heat treatment. High melting point alloy: for example, copper, ferrous metal, etc., the die casting life is low; it is not suitable for small batch production, the main reason is the high manufacturing cost of aluminum castings, high production efficiency of die casting machine, and uneconomical small batch production.

Die casting has a wide range of applications. Aluminum casting is one of the metal forming methods. This is an effective way to realize the chip less and chip less. It is widely used and develops rapidly. At present, die casting alloy is no longer limited to zinc, aluminum, magnesium, copper and other non-ferrous metals, but gradually expanded to cast iron and steel castings. The size and weight of the die casting depends on the power of the die casting machine. With the increase of the power of the die casting machine, the shape and size of the casting can be from a few millimeters to 1-2 meters, and the weight can be from a few grams to dozens of kilograms. Foreign aluminum castings with diameter of 2M and weight of 50kg can be die cast. Die casting is no longer limited to automobile industry and instrument industry, but gradually expanded to other industrial sectors, such as agricultural machinery, machine tool industry, electronic industry, national defense industry, computer, medical equipment, clock, camera, daily hardware and dozens of other industries. In the aspect of die-casting technology, there are many new technologies such as vacuum die-casting, oxygen filling
