Abstract

Sinks occurring in the rib portion of the testing product for the unpainteds are fatal defects at surface quality. In this study, we carried out moldflow analyses for several factors that affect the sinks. The result tells us large important effective factors on sinks by analyzing sink marks estimate. We expect practical use as reference for performing analysis or manufacturing products with rib designs and injection moldings which minimize sink-marks surrounded ribs.
