The subject of the invention relates to the technical sector of the working of materials, without substantial removal of material. According to the invention, the element acting as punch (force plug) 1 is fixed by being shaped and arranged in order to be deformed, under a compression force, in a temporary, continuous or intensity-adjustable manner, depending on the shapes and sizes of the hollowed mould cavity 5a, the material interacting with bearing and positioning means capable of allowing the deformation operation. <IMAGE>
