This study simulates cooling of a metal mold in 3-dimensions, compares it with experiments, and furthermore, attempts to establish a more precise simulation. We have analyzed heat generation at a gate and resinous flow in a cavity, and have considered the mold-temperature field in the filling process. The code enables both re-construction of 3-dimensional any practical molds with water jackets and its reform. Moving coordinates system is used to calculate the transient temperature-field in polymer-flow. As a result, we have been able to confirm agreements between the results of the experiment and the simulation. Therefore we have found that we are able to apply this program code to practical cooling process. There are still some problems in its further advancement, but this study is a foundation for cooling simulations.
