A process for the manufacture of cookie molds for the casting of pieces of magnetic material, characterized by the specific combination of the following operations: Preparation of a model plate, placing on the same of the models of the parts to be obtained, together with the precise feeding troughs, arrangement, in said model plates, of cover-boards that determine the thickness of the cookies, in order that they have the sufficient consistency to be filled with metal at high temperature, heating of the cold plate at a temperature approximately 200 to 250º C, cleaning the plate with pressurized air, application thereto of a film of a separation or demolding agent, consisting of an aqueous solution of an organic silicon compound, filling the model plates with sands of molding whose grains are coated with a film of a thermosetting binder, said sand being of very fine grains, smoothing d the molding sand on the plate to produce a flat upper surface and heating of the assembly at a temperature of approximately 500º C for a time of 3-4 minutes which may be varied according to the volume of the cookie and, finally, demolding the "cookie mold" produced.
