Abstract This paper presents a study of the characteristics of axial vibration of a screw in the filling process for a novel dynamic injection molding machine. By simplifying a generalized model of the injection screw, physical and mathematic models are established to describe the dynamic response of the axial vibration of a screw using the method of lumped-mass. The damping coefficient of the screw is calculated in the dynamic filling process. The amplitude-frequency characteristics are analyzed by the simulation and experimental test of polypropylene. The results show that the amplitude of a dynamic injection molding machine is not only is related to structure parameters of the screw and performance of the material, such as non-Newtonian index, but also depends on the processing parameters, such as vibration intensity and injection speed.

Numerical simulation in the printer cover product molding process with gas assisted injection molding was carried out by means of computer aided engineering. The filling process and surface quality were forecasted. The simulation results provide an important reference for the selection in the production process parameters. Compared with the production molding process and the actual product, CAE technology used in actual production and design is entirely feasible.
