Abstract: This review article deals with the importance of process parameters and the recent developments in modern tool technology in the success of smart productivity for casting process of all types. Various influencing factors such as design, location and the number of gating on feeding mechanism were discussed vis-a-vis casting defects. The review revealed reduction in the defects such as air bubbles, blow holes, shrinkage defects and mechanical properties of the casting parts through selection of an optimum feeding design. Variations in fillet radius and thickness on the feeding system were found to be the factors affecting the location of the hot spot. Accordingly, the mobility of the hot spot was controlled by geometrical modifications in the feeding system. In addition, the formation of pinholes and solidification defects could be reduced through a proper arrangement of the feeding system. The rapid growth in implementing simulation techniques in the casting process can assist the enhancement of yield with minimum production cost. This article provides a data base relating to the merits and demerits of various factors and material systems with their industrial applications for enabling further research in the casting process.
