Abstract:

According to the volume pulsation injection⁃molding technology and equipment, the effects of pulsation force field on the flowability, cavity pressure response, and microstructure of polymeric materials were analyzed by means of the experimental data. The strengthening effects of pulsation force field on injection and packing processes were clarified. The self⁃toughening and self⁃reinforcement of immiscible polymer blending systems under a pulsation force field were revealed. The advantages and potential applications of the pulsation force field in optimizing the injection⁃molding process and improving the service performance of injection⁃molded products were clarified through introducing the research progress in the volume pulsation injection⁃molding technology.

Key words: pulsation force field, injection molding, polymer
