Abstrakt: The article discusses the development, confirmation and establishment of three-dimensional numerical simulation for injection molding filling of 3-D parts with microsurface features. The mixed model and the equal-order model were utilized to solve the Stokes equations with three different tetrahedral elements for the determination of verification and comparison. Injection molding has been a significant manufacturing process for the mass production of complex plastic parts processed.
