Design and Manufacturing of Defect-Free PumpCasings: A Numerical and Experimental Approach

Internal shrinkage defects often occur in sand-cast gray cast iron pump casings, particularly in areas with abrupt thickness variations where heat dissipation is limited. These defects form during the final stage of solidification when isolated liquid metal cannot be properly fed. In this study, the solidification beha...
