Abstract
An injection molding process for soles using expansible and cross-linking EVA based compounds. During the cooling stage of the molded sole, the spontaneous shrinkage of the molded sole is arrested by means of a template placed on the sole. To accomplish this, a series of perimeter pin elements extend from the bottom surface of the template and are coupled with a corresponding series of perimeter holes defined on the upper surface of the sole. The dimensions of the sole therefore will reduce no further either during the remaining cooling phase or after cooling.
