Mold temperature can influence the overall cycle, shrinkage, warpage, crystallinity, and other characteristics of a molded part. Amorphous Eastman polymers require colder molds than some other plastics, therefore proper attention to cooling is critical. After the mold is designed and constructed, one must insure that adequate turbulent flow is provided for the cooling channels. Turbulent coolant flow ensures optimum heat transfer as it allows more of the coolant to be exposed to the core and cavity channels. |
