This is a study to solve the problems that occur in plastic injection molding. Temperature control of the mold in injection molding is very important because it is a heating and cooling operation and has a decisive influence on the productivity and merchantability of the product. We have developed a technology to uniform the resin density of the injection molding products by heating the mold temperature to high temperature within a short time and to develop the cooling speed and cooling temperature control system. A small test bed was made to test the heating and cooling performance, and the heating and cooling performance was tested by thermo-imaging the heating and cooling performance. It was applied to development molds and general molds. In the developed molds, there were no flowmark and weld lines that we wanted to improve.
