Injection molding is most frequently used manufacturing processes in the plastics industry. In the plastic injection molding process the cooling channel has an important role for the cooling process of the product. The good cooling channel is indicated by the ability to absorb heat from the product quickly and uniformly on the each side of the product. This study compared straight and conformal cooling channels with diameters 8 mm to know it is effects on pattern of temperature distribution in the mold and cooling effectiveness of the product inside mold using Fluent software. Analysis of virtual model images shown that those with conformal cooling channels can predict significant heat absorption compared with straight cooling channel.
