Analysis of Injection Moulding Process Parameters on PVC Material via Taguchi-ANOVA

Abstract

This paper deals with the development of prediction model for injection moulding machine using Taguchi. In this work, all the process parameters namely filling time (FT), refill time (RFT), tonnage time (TT) and ejector retraction time (ERT) are modeled using Taguchi method. PVC (polyvinylchloride) taken as process material in this experimental work under optimal working conditions. The influence of filling time (FT), refill time (RFT), tonnage time (TT) and ejector retraction time (ERT) on cycle time (CT) is examined in the process. The experimented result is examined through ANOVA. From the basis of experimented result via Taguchi method, it is found that filling time (FT=23 sec) and tonnage time (TT=.68 sec) have significant effect on output parameter (CT) and the other parameters refill time (RFT) and ejector retraction time (ERT) have insignificant effect.
