Polypropylene morphology in micro-injection molding of rectangular groove

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

In micro-injection molding process, the dimension of the characteristic geometry can be similar to morphological feature size inside the polymer. This work investigates the crystalline morphology in the injection-molded polypropylene parts. It has been found that development of crystalline structure affects the filling flow. The molded micro-structure shows the crystalline growth on the surface. The crystalline structure inside micro-groove can be stretched crystal or spherulite.
