In metal injection molding (MIM), it is important to reduce flash and flow mark as much as possible for high quality and high productivity on each MIM green parts. The back flow that occurs in injection process and the ability of injection response affect flash and flow mark. In this study, the experiment using the spiral-flow tester and the medical clip mold are carried to compare V-LINE injection molding machine (V-LINE) that plasticizes with the single screw and fills with the plunger to In-line injection molding machine (In-line). The experiment using the spiral-flow tester shows that the flow length molded by V-LINE is longer than that one molded by In-line. And the experiment using the medical clip mold shows that V-LINE can reduce flash and flow mark more than In-line.
