Numerical Studies of Flow-Induced Defects in Aluminum Ingot Die Casting Process
A numerical modeling of aluminum die casting is discussed in this paper. Emphasis is laid on the flow-induced defects including air entrainment and oxide tracking. An ingot die casting process is designed by considering both laminar zone and turbulence zone. Pure aluminum is used as the casting material. In addition, different process parameters and different shapes of sprue are presented to check their influence to the flow status and flow-induced defects.
