Abstract
A method of forming a foamed cellular thermoplastic article configured from partially expanded granules of an expandable thermoplastic material comprising, flowing said particles with a substantially dried heated gaseous agent into a mold space defining the shape of said article, so that said granules enter said space at a temperature higher than the softening point of the thermoplastic material but lower than the temperature at which a substantial expansion takes place, apply an air extraction vacuum next to the insertion part of said granules for prevent the formation of pressure in said space, then subject said granules in said space, without further heating, to a vacuum to expand and join said granules together to form said foamed cellular plastic article that adapts to the shape of said space and then remove the article from that space.
