Tobin’s ANTEC “Nuggets”, part II: Conformal cooling of mold cavities—where it works and where it doesn’t


While there were several papers presented on validation of mold-fill simulations, another type of validation was very intriguing: conformal cooling.

Editor's Note: PlasticsToday sent injection molding expert and 45-year veteran of the plastics industry, Bill Tobin to the Society of Plastics Engineers (SPE) ANTEC annual technical conference to get an expert's take on all things injection molding at the event. This is the second installment in a three-part series.

For us Luddites who are still prone to drilling straight holes in steel for waterlines, conformal cooling uses lines that are parallel to the exterior contours of a part.

Those of us who learned about waterlines know the closest waterline should be two diameters from the surface of the part and no more than six diameters from a parallel line for the same surface. Now the wizards from academia come in:...
