Abstract:
A foamed article producing system comprising:a preparing apparatus which prepares a molten gas-dissolving-resin having a great number of cell nucleators by diffusing a gas in a synthetic resin in a molten state under conditions of a predetermined temperature and a predetermined pressure; and a molding apparatus which foams and molds the gas-dissolving-resin supplied from the preparing apparatus into a foamed article having a great number of cells, the molding apparatus including at least two mold members which define a mold space therebetween and are movable relative to each other, said mold space being expandable when said gas-dissolving resin is being foamed; and a controller for controlling a mold driving mechanism to move at least one of the mold members to increase the mold space in response to a signal after the molten gas-dissolving-resin is filled in the mold space.
