Influence of Heat Sink on the Mold Temperature of Gypsum

Influence Of Heat Sink On The Mold Temperature Of Gypsum

Gypsum molds have been developed as an alternative for the Rapid tooling (RT) method used in injection molding. However, the poor capability of the heat delivery forces the gypsum mold to operate under a high-risk condition, and distortion of the molded part becomes apparent. The goal is to investigate the effect of a heat sink on the reduction of the gypsum mold temperature
