Abstract
The effects of processing parameters on surface roughness of microcellular injection molded PC parts were investigated. Taguchi design of experiments (DOE) was performed with varying mold temperature, melt temperature, injection rate and supercritical fluid (SCF) concentration. It was found that mold temperature, injection rate and melt temperature appear to be the predominant molding parameters which affect the surface roughness. The results are helpful for designers to optimize the process conditions to achieve high quality microcellular PC part.
