Injection compression molding process was applied to examine how controlled compression pressure can influence the crystallinity and light absorbance in poly (ethylene terephthalate) (PET). Several interesting results are obtained: (1) The crystallinity of molded parts was increased with increasing compression pressure in PET whereas it was decreased in PP. (2) It was possible to control the skin-core region and crystallinity in the core region by intentionally controlling the compression pressure during the solidification process. (3) The simulated crystallinity distributed in the thickness direction was in good agreement with experiment at various compression pressures. (4) Lambert-Beer's law was found to be applicable for the relationship between average crystallinity and light absorbance.
