Feeders have been located closest to major hotspots to allow feed metal transfer during volumetric contractionthat accompanies solidification shrinkage. The feeder according to the design dimensions has been placed exactly onthe top of the hotspot as shown in Fig. 8. In this case, various modulus obtained are; modulus of feeder is 10.36 mm,modulus of neck is 9.75 mm whereas the casting modulus is 6.471 mm.
