摘要

In order to reduce weight and improve the dimensional accuracy of plastic products, microcellular injection molding technology is applied more and more in automotive. There are several defects are paid special attention by vehicle manufacturers, such as warpage and cell radius. This research investigated the effects of processing parameters in microcellular injection molding. The study investigated the influence of two kinds of gas foamers (CO2 and N2) on microcellular injection molding process, and the following processing parameters such as temperature, time, pressure and gas controlling were considered to research. Design of experiments was employed to perform the experiments. According to experimental analysis, not only the significant processing parameters to warpage were found out, but also the interactions between each factor were investigated. The results of this study could provide microcellular injection molding process design with theoretical basis and practical guidance.
