Abstract
Many parameters influence the warpage developing at the corners of injection molded plastic parts. One of the main causes of this deformation is the asymmetrical cooling of the injection mold. This study presents an injection molding analysis of the heat flow developing in injection molds. The analysis shows that significant temperature difference appeared between the two sides of the mold after the hot polymer melt had filled the cavity. It was highlighted that the unevenness of the cooling should be considered during the mold design in order to avoid the warpage of the parts.
