Producing a defect-free casting for a critical application is a challenging job mainly due to two factors.Primarily due to trial and error approach towards the design of riser, runner, gates, sprue, mold cavity, core andchapstics. The other factor is not being able to maintain a good quality of the melt. Defects are the results of a merger ofseveral causes. In this study, the authors have chosen to use a FEM based commercial software to design riser andemploy chills to eliminate or minimize the shrinkage defects. The use of chills promoted directional solidification suchthat the shrinkage cavities moved along the solidification front and away from casting into the riser. Study is made onuse of blind riser, open riser and their influence on shrinkage porosity.
