ABSTRACT:
A process for making a foamed shoe sole includes (a)forming at least one unexpanded blank in at least one first mold by introducing thereinto a resinous molding composition, which includes an agent capable of expanding and cross-linking the resinous molding composition, at a temperature lower than that which can cause the composition to expand and cross-link; b) trimming the unexpanded blank to remove flash and inspecting the weight and size of the unexpanded blank; and (c) placing in a second mold the unexpanded blank having a predetermined weight and size and heating the unexpanded blank under pressure at a high temperature sufficient to cause the unexpanded blank to undergo expansion and cross-linking, whereby the sole so produced has good cross-linking characteristics and retains exactly the shape and size of the mold cavity of the second mold. Preferably, the resinous composition contains polyethylene vinyl acetate.
