Abstract

Abstract: In this paper, CAE and Taguchi DOE(design of experiment) technique were combined to investigate the influence of process conditions on the warpage of injection molded parts. Experiments on L16(215) orthogonal array with interaction of factors and L9(34) orthogonal array were carried out to minimize the warpage of injection-molded parts. For the factors selected in the main experiments, holding pressure and melt temperature were found to be the principal factors affecting the warpage of the injection molded parts. Under the optimum factor levels, the warpage of injection molded parts was decreased by 34.23 %.

Key words: injection molding, process optimum, warpage
