Abstract :In this study, an experimental research has been carried out for the production of plastic injection molds with conformal cooling channels by laminated brazing. In order to increase the efficiency of the cooling system, conformal cooling channels are designed. Mold cores and cavities were cut into layers and machined into plates. The plates are combined with vacuum brazing method to produce plastic injection mold with conformal cooling channels. The production of plastic parts was tried with two molds with conformal and straight cooling channels. According to the results, both the cycle time and the preparation time of the plastic injection mold for production were shortened by the use of conformal cooling channels.
