Abstract
Shrinkage porosity is common defect found at casting junctions. Slowly, cooling of molten metal causes hot spot area generation at the junction that is the cause of defect such as shrinkage porosity. Location of riser above the junction may be the one design change for minimization of defects. The hot spot area size and its extent depend on geometrical complexity like thickness, fillet radii, and the angle between walls. Alternatively, junction modification is one of the optimum solutions to minimize such hot areas before solidification. Pro Engineering was used for modeling and through STL, files format data exchange to AutoCAST. Taguchi and ANOVA methods were employed to evaluate the influence of parameters on hot spot area in casting junctions. Area of hot spot was selected as the response variable. It is concluded that upper thickness makes the maximum contribution, and lower thickness, radius, and angle followed upper thickness.
