Experimental Investigation for Minimization of Casting Defects Using Taguchi Method

Abstract

In this work, an attempt is made to reduce Molding defects using Taguchi Method. The input parameters used are Runner Lower Diameter, Runner Upper Diameter, Runner height, In gate height, and Pouring time. The response parameters selected as per the study of molding process requirements of the industry are Product yield(%). The L8 orthogonal array is used as per Taguchi method. The experimentation is conducted and the responses are measured. Significant progress has been made in determining the appropriate values of molding process variables to expand molding quality using diverse techniques during the last few decades. The design of sand-molding process variables has been recognized as one of the most critical aspects of molding quality. This research work focuses on improving the molding quality and yield percentage. The data analysis is made by S/N ratio and ANOVA. The result revealed the optimal setting to minimize the defect.
