A porous mold for obtaining, by molding under pressure, articles of natural or synthetic and vulcanizable polymers, essentially characterized in that it is constituted by a porous metallic body, of which at least part of its useful surface is coated with a porous non-stick plastic material penetrating the pores corresponding to said surface, at least in a certain depth, whereby the finished article presents its surface devoid of bubbles that would otherwise originate because of the air and eventually of the gases produced during the molding operation, which with this coating are expelled from the mold.
