The objective of this study is to minimize warpage at the opening of an injection-molded component for automobile door locking mechanism by optimizing the cooling channel design and molding conditions. Experiments were initially conducted using Taguchi"s orthogonal array and the face-centered central composite design method, followed by statistical analysis to determine the optimal design conditions for the peripheral cooling channels and molding conditions. A simulation experiment was conducted to validate the predicted optimal design conditions, which yielded a warpage of 0.8319 mm. To further reduce the warpage, serial- and baffle-type cooling channels were installed between the head and opening of the product. A full factorial experiment was conducted to optimize the design variables for each channel type. The internal cooling channels significantly reduced the fluctuation of the mold surface temperature to maintain the allowable warpage limit of 0.7 mm. Comparisons of the warpage values confirmed that baffle-type internal cooling channels provided more uniform cooling and effectively reduced warpage compared with serial-type channels.
