Study of the flow mark in the precision injection molding of PP/rubber/talc blend |
| 초록 |
Flow mark is a kind of surface defect that can arise during the filling stage of the injection molding process. The purpose of this study is to clarify a mechanism of the flow mark that appears on the surface of injection molded PP through the observation of the surface structure. The materials used in this experiment were PP/rubber and PP/talc compounding, which were widely used for automobile part. The flow mark had two different constitutions, such as a luster part and a cloud part, alternately on the both surface. We found that the cloud part was a filler rich state form. The structure of the cloud part was quite different from luster part. We investigated the surface structure of PP/rubber and PP/talc composites by using IR, SEM, EDS. Also we investigated flow mark length percent and flow length. |
