Abstract
In this study, the casting process using forged insert was investigated to characterize the manufacturing process by which good mechanical properties can be obtained when compared with existing casting products. Process analysis for the casting design was performed by using FVM (Finite Volume Method) software. In pouring process, three kinds of candidate gating systems are considered and analyzed respectively. The molten metal behavior in gating system is so important that it affects the solidification behavior of the cast. The results show that as the number of gates is increased, hardness of cast was increased and gaps of cast with forged insert were decreased.
