The present invention relates to a lost-wax moulding method. According to the invention and in order to produce the wax cluster, nestable rings 1 are moulded from special wax to form a stack, these rings having radial bores 4; the patterns of articles 8 are moulded from special wax, with an integral rod 11 ending in a cylindrical stud 12 at the diameter of the bores of the rings, and a stack is made of a certain number of rings, with a conical base 5 at the base of the stack, and the cluster is assembled by engaging the cylindrical studs 12 of the patterns in the bores 4 of the rings 1; then, the cluster thus constituted is used to produce the plaster mould. The invention is applicable to all metal mouldings customarily produced using the lost-wax method. <IMAGE>
