Abstract
Method for molding very thick objects, especially shoe lasts, characterized in that the operative process comprises the preparation of a mixture containing: on the one hand, from 75 to 85% of wood flour or other natural element, to which is added a plasticizing substance; and for another 15 to 26% of a thermosetting resin, which enriches the first component; whose mixture, in a single mold and by means of a machine or press suitable for the molding to be made, is homogenized, pre-heated, transferred, injected and compressed obtaining the molded piece suitable for machining and polishing.
