ABSTRACT
This Present study has been made to optimize the process parameters during forming of PVC (L-bow) fitting by injection moulding machine using response surface methodology (RSM).Four input process parameters of injection moulding machine namely filling time, refill time (RFT), tonnage time (TT) and Ejector retraction time (ERT)) is chosen as variables to determine the process performance in terms of cycle time (CT). The analysis of variance (ANOVA) is carried out to determine the effect of process parameter on process performance. The parameters filling time (23), refill time (36) tonnage time (0.68) and Ejector retraction time (1.36) are identified as the most significant optimal setting for Cycle time (CT).
