Optimization Plastic Injection Mold Cooling Channel

Heating the mold by using high-temperature fluid such as hot water, oil, … is the simplest and cos-effective solution. Different from the traditional cooling channel is just the straight hole through the mold, a conformal cooling channel was implemented based on the idea that the cooling channel path closely matched the molding profile, so the temperature transferred from the fluid in the cooling channel was distributed uniformly in the mold surface. In this study, three approaches included Taguchi, RSM, and ANN was used to found the optimum parameter of cooling channel. The optimum shape observed from three approaches proved that, conformal cooling channel show the better effectiveness than straight cooling channel when used for heating the mold surface.
