Recently, Polymer and injection-molded foam processing are widely used in many industries. In these cases, the molding conditions are very important. We reported the flow process, temperature distribution, stress distribution and warpage by FEM simulations and experiment in several inject conditions. Especially, injection gates arrangement which is the one of the most molding conditions that is investigated on the influence of molten resin flow up to the cavity. Therefore, in the experiment we made a visual Mold and Die Set that researched on epoxy resin flow by image analysis used it. As a result, it is important to reduce the warpage that the number of gates for injection molding is as many as possible or the Die and Mold temperature makes maintain in around glass transition temperature of used materials.
