In the 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 of injection molding machine 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 using V-LINE is 29% longer than that one using In-line. And in the experiment using the medical clip mold shows flash and flow mark can be reduce by using V-LINE than In-line.
