Abstract
The invention relates to systems and methods for creating a foamed part. An example method includes providing a polymer processing system, providing a mold having at least one expandable mold cavity 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.
