The Effect of Injection Molding Parameters on Microcellular Foam Morphology
(2021)
Microcellular foam injection molding with physical blowing agent (MuCell®) delivers monetary benefits, processing advantages and freedom of product design by reducing shrinkage. In conjunction with an advanced mold technology, so-called Pull and Foam method, there is great potential in controlling the foam structure of the component locally. In this study, Polycarbonate (PC) components were produced with nearly compact outer skin and a closed cellular core. To understand the relation between processing parameters and ...

Effects of the Cellular Morphology on Fatigue Deformation Mechanisms of Physically Foamed Polycarbonate
(2023)
In this study, the tension–tension fatigue behavior of foam injection molded thermoplastic microcellular Polycarbonate (PC) is characterized. The variation in morphology is obtained by modifying the mold temperature, injection volume, injection flow rate, and blowing agent content (physical and chemical) in the polymer melt. The relationship between the wide range of morphological qualities and relevant fatigue properties is made explicit via a statistical correlation coefficient analyses. The analysis is made between ...
