A system and process for injection molding polymer articles is described. The system and process are designed to reduce gate blush. In one embodiment, an injection molding device injects a molten polymer composition into a mold cavity adjacent to an interior curved surface on the mold. The flow of the polymer material is parallel to a line that is tangent to the curved surface. 描述了一种用于注塑聚合物制品的系统和方法。该系统和方法被设计用于减少浇口白晕。在一个实施方式中，注塑装置将熔融聚合物组合物注入模具腔体中，该模具腔体与模具上的内部弯曲表面相邻。聚合物材料流平行于与弯曲表面相切的线。
