A process for the manufacture of thin-walled mask molds from a granular filler and binder material which is hardened by heat in the cavities corresponding to the definitive thickness of the mask of heated molds by introduction of the material of molding under pneumatic or mechanical pressure, characterized in that the molding tool is subdivided into a plurality of sections separated from each other by tensile parts and the sections are successively filled with molding compound, in which, after filling a section, it removes the traction piece that limits the next section, so that the molding material, which has not yet hardened completely, joins all the sections, when fully hardened, to form a piece of unitary mask mold.
