Document Type and Number:
Japanese Patent JP6616398
Kind Code:
B2
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 a foamed preform. Thereafter, the foamed preform may be inserted into a compression mold to press-form the foamed preform into a finished part.
