Influence of a locally variable mold temperature on injection molded thin-wall components

Abstract

Regarding injection-molding of semi-crystalline thermoplastics, controlling mold temperature and, therefore, the polymer melt's cooling conditions can significantly affect component properties. In this research, an innovative dynamically tempered mold technology with different temperature zones is investigated, which will allow the production of thin-wall components with locally different component properties. First results show that due to influencing inner component properties, significant differences in optical and mechanical component properties can be achieved.
