Micro injection molding: characterisation of cavity filling process
Zhang, Nan; Chu, J. S.; Gilchrist, M. D.
SPE-ANTEC 2011, May 1-5, 2011, Boston, MA, U.S.A. Based on reciprocating micro injection molding machine, this paper characterizes the influence of machine process parameters and its transition response from velocity control to pressure control (V-P transition) on the micro cavity filling process. The method of Design of Experiment was employed to systematically and statistically investigate the effect of machine parameters on actual cavity filling process, which was described by the defined process characteristic values (PCVs). The statistical analysis of the experiments indicated that injection speed was dominated factor affecting all PCVs in cavity filling process. It was also found that the machine V-P transition have significant effects on cavity filling. Other funder Chinese Scholarship Council and Enterprise Ireland (Grant No. CFTD/07/314).
