(1) Metal parts with messy shapes, clear outlines, thin-walled deep cavities can be made. Because molten metal maintains high fluidity under high pressure and high speed, it is possible to obtain metal parts that are difficult to process by other processing methods.
(2) The dimensional accuracy of
aluminum die-casting parts is high, up to IT11-13, sometimes up to IT9, and the surface roughness can reach Ra0.8~3.2um, and the interchangeability is good.
(3) High material utilization rate. Because of the high precision of
aluminum die-casting parts, they can be installed and used only after a small amount of machining, and some aluminum die-casting parts can be directly installed and used. The material utilization rate is about 60%~80%, and the blank utilization rate reaches 90%.
(4) Production. Because of the high-speed filling, the filling time is short, the metal industry condenses, and the die-casting operation cycles. Among various casting processes, the yield rate of die-casting method is suitable for mass production.
(5) Facilitate the use of inserts. It is easy to set a positioning mechanism on the die-casting mold to facilitate the insert casting of inserts and meet the local performance requirements of aluminum die-casting parts.
