Die-casting: It is to press the metal solution at high speed into a precision metal mold type cavity, and the metal fluid is cooled under pressure to form a casting.
advantage:
1. When the die-casting, the metal liquid is high, and the flow rate is fast.
2, the product quality is good, the size is stable, and the interchangeability is good;
3, high production efficiency, number of die-castings;
4. Suitable for a large number of mass production and economic benefits.
shortcoming:
1. The casting is easy to produce fine pores and strain.
2, the plastic resistance of die castings should not work in the absence of shock loads and vibration;
3, when high melting point alloy die cast, the mold life is low, affecting the expansion of die casting.
Application: The die casting is first applied in the automotive industry and instrumentation industry, and later gradually expands to various industries, such as agricultural machinery, machine tool industry, electronics industry, national defense industry, computer, medical devices, watches, cameras and daily hardware and other industries..
