N2 - The convective heat transfer coefficient of the mold is an important parameter in the numerical simulation of the injection molding process, and it significantly affects the results. This influences many factors related to processability including the time required for filling and solidification. This study examines the previous work on this coefficient, including commercial implementations, and explains its characteristics. From real cases, the filling time, solidification time, and pressure distribution have been presented according to this coefficient, and a method for treating it is suggested.
