INJECTION MOLDING SYSTEMS AND METHODS FOR FORMING MATERIALS USED IN FOOTWEAR AND MATERIALS MANUFACTURED BY SAID SYSTEMS AND METHODS
摘要
The invention relates to systems (100) and methods for creating a foamed part. An example method includes providing a polymer processing system, providing a mold (150) having at least one expandable mold cavity (152) in fluid communication with the polymer processing system, mixing polymeric material and blowing agent within the polymer processing system to produce a unfoamed mixture, injecting a volume of the mixture of polymeric material and blowing agent from the polymer processing system and into the expandable mold cavity, and expanding the mold cavity to expand the unfoamed mixture within the mold cavity and form the foamed part.
