Flow analysis of injection-press molding process
We developed a method to determine the characteristics of a press machine required Sor the injection-press molding process. In this paper a model based on a serial spying connecting two different springs was used. One was spring represented apparent machine rigidity and the other the resistance to compression of the resin. Using this model, we calculated the flow between parallel plates and flow behavior in a ''tray'' mold.
