Metal casting is one of the basic manufacturing processes. The gating and riser system design plays an important role in the quality. Due to the lack of existing theoretical procedures the designing processes are normally carried on a trial and error basis. The casting produced by foundry with internal shrinkage as a major defect was analyzed and identified that gating and feeding system reduced defect and increase yield. Many casting defects, which cannot be eliminated by changes to tooling and process parameters, can be attributed to poor design of the part with respect to manufacturability. One such common defect is shrinkage porosity at casting junctions. The defects can be predicted by casting solidification simulation, and corrected by minor modification to part design. Finally, a more reasonable gating system was obtained by analysis of drawing and method effective calculations. In the current global competitive environment there is a need for the components in short lead time. Defect free castings with minimum production cost have become the need of foundry.
