Production of Plastic Injection Molds with Conformal Cooling Channels by Laminated Brazing Method

Abstract

In this study, an experimental research was carried out for the production of plasticinjection molds with conformal cooling channels by laminated brazing method. In thiscontext, plastic injection mold conformal cooling channels was designed andmanufactured. In order to obtain three-dimensional complex cooling channels, mold coreswere separated into layers and processed as plates in different thicknesses. These plateswere combined with the vacuum brazing method. For the comparison, another mold witha linear cooling channel was produced. Plastic parts were produced by using both molds.In the experimental study, the cooling time, the surface temperature of the product andthe distortions in the product were examined. According to the results, it was determinedthat by using of conformal cooling channels, the cooling time decreased by 22%. It wasalso observed that there was nearly 50% decrease in the amount of warpage on theproduced plastic parts.
