Numerical Simulation And Experimental Investigations On The Effect Of Polypropylene Rheology In The Injection Molding Process

The design and fabrication of the mold are costly for the injection molding machine. Prior to the fabrication process, the prior to molding analysis is important to investigate the flowability of molten plastic in the mold design. The pre-molding analysis is carried out using simulation software,...
