ABSTRACT
Usually, the permanent mold casting process means that the metal mold (die) casting process occurs with gravity pouring. In this chapter, however, permanent mold casting processes are interpreted as all metal mold (die) casting processes regardless of the way the molten metal is being introduced. The reason for this interpretation is that all metal mold casting processes have similar solidification characteristics. Thus, the traditional permanent/semipermanent mold casting, tilt-pour, and low-pressure casting processes are all included in this discussion. In terms of solidification simulation, high-pressure die casting and squeeze casting are similar to permanent mold casting. However, due to the significant difference in the mechanism to introduce molten metal into the die cavity, the mold filling analysis for high-pressure die casting and squeeze casting is quite different from that of the permanent mold casting processes and is discussed separately in Chapter 13.
