Die-casting process is characterized by low cost, good workmanship, and resolving saves resources and energy. The application and development of this material will not fade away. For example, cupola-electric furnace double-connection smelting technology and equipment; Iron liquid desulfurization and filtration technology are widely used. Manufacturing technology of thin-walled cast iron parts; Cast iron composite material manufacturing technology; Use cast iron parts surface or local technology; Matching technology of isothermal spheroidal graphite iron; Process and equipment of metal Die Casting, metal sand coating casting, continuous casting, etc.

Die-casting light alloy is widely used in aviation, aerospace, automobile, machinery and other industries due to its low density and a series of excellent characteristics. Especially in the automotive industry, it is a long-term development trend to replace steel and iron castings with aluminum and nickel alloy castings in order to improve the utilization ratio of fuel consumption.

Advantages of die casting process:

1) Metal parts with disordered shape, clear contour and thin wall and deep cavity can be made. Because molten metals maintain high fluidity at high pressures and speeds, hard-to-process metal parts can be obtained by other processes.

2) Die castings have high dimensional accuracy, up to IT11-13 grade, sometimes up to IT9 grade, surface roughness up to Ra0.8~3.2um, and good interchangeability.

3) Material. Because of the high precision of die castings, they can be installed and used only after a small amount of machining. Some die castings can be installed and used directly. The material utilization ratio is about 60%~80% and the blank utilization ratio is 90%.

4) Production. Because of high-speed filling, short filling time, condensation of the metal industry, die casting cycle. In various casting processes, the die casting method has a high yield and is suitable for mass production.

5) Convenient use of inlays. It is easy to set positioning mechanism on the die-casting die, convenient to inlay the casting inlay and satisfy the local performance requirements of the die-casting parts.
