In this study, we investigated the injection molding (IM) process for the production polymeric parts with thin walls. The injection molding process was numerically modelled, and thin-walled polymeric parts were injection-molded experimentally. In the case of polymeric parts with thin walls, it is critical to understand flow and heat transfer behavior in the mold during the process. Injection-compression molding (ICM) was adopted to fabricate the parts, and the resulting residual stress and warpage were evaluated. In addition, birefringence of the molded part was analyzed to validate the numerical results.

注塑成型在薄壁聚合物零件上的应用

在这项研究中，我们研究了用于生产薄壁聚合物零件的注塑（IM）工艺。对注塑过程进行了数值建模，并对薄壁聚合物零件进行了实验注塑。对于具有薄壁的聚合物零件，了解过程中模具中的流动和传热行为至关重要。采用注塑成型（ICM）来制造零件，并评估由此产生的残余应力和翘曲。另外，分析了成型件的双折射以验证数值结果。
