Abstract

Abstract: The method of strength check for the for-barrel of high pressure screw-plunger injector was introduced based on a case study. The stress and deformation of the for-barrel was analysed under maximum injection pressure by using finite element analysis software ANSYS. Finally, the flow state of the melt in injection unit under specific conditions was simulated. Such results provided a theoretical basis for the design of the for-barrel and the control of the injection speed.

Key words: screw-plunger injection molding machine, injection unit, numerical simulation
