| Abstract: | The plasticizing process of a rotating disc screw in the disc-screw micro injection molding machine was simula-ted by using the COMSOL Multiphysics finite element simulation software. The phase change of polymer flow and the heat transfer in the cavity were analyzed during the rotation of the screw. The analysis and simulation results indicated that the heating temperature had greater impact on the plasticizing performance under the premise of the same screw structure， and however the rotate speed had a smaller impact on the plasticizing performance. Base on these simulation results， this paper provides a reference for the structural optimization of the disc screw. |
