Process for the manufacture of blocks and flexible plates of foamed synthetic resins, by steam treatment of pre-foamed beads of polyolefin resins in a molding cavity, characterized essentially by the fact of carrying out the molding of the pre-expanded bead load necessary for the obtaining the desired object, within a molding cavity of smaller volume than that of said object and allowing the aforementioned load to expand as its pressure in the molding process increases until reaching the definite volume of the object, the blocks or plates being obtained in this way finally subjected to a compression process.
