Abstract
A process for forming a thermoplastic, cellular and foamed shaped article comprising the dragging of granules of a thermoplastic material extendable in a heated gaseous medium, the flow of said dragging in a space that determines the configuration of said article while heating the said granules at a temperature above the softening temperature of the thermoplastic material but below the temperature at which a substantial extension is effected as the granules flow into said space, after which the aforementioned granules are subjected to said space to a vacuum for the said granules to extend and melt to form a plastic, cellular article to adapt to said space, and then remove the article from said mold.
