Shrinkage Defect Elimination in Ductile Iron Casting using Virtual Solidification Simulation

The vital stage in manufacture of castings is the formation of solid casting from molten metal when poured into mould cavity. The various complex transformations that occur during the process influence the quality of the casting. The design of risering system which ensure freedom from shrinkage and other solidification oriented defects in the casting play a vital role in the quality and yield of the casting. A good design will produce castings free from these defects and considerably improve the yield. this paper describes the removal of shrinkage defect in Ductile Iron casting by redesigning the risering system using Virtual casting simulation software MAGMASOFT and CAD software PROENGINEER.
