ABSTRACT:
The present invention consists of a method for gauging a mold cavity to be used in the injection molding of a foam product, such as a sole of an article of footwear. The method comprises the steps of selecting a durometer for the product, determining a thickness expansion ratio based on the durometer selecting a thickness value, selecting a material based on the thickness value and thickness expansion ratio, dividing a model of the final product into a plurality of sections, determining a length/width expansion ratio for each section, gauging a mold model for each section based on the expansion ratio for each section, and constructing a composite mold model using the guaged sections.
