PROBLEM TO BE SOLVED: To produce a component of improved rigidity.SOLUTION: A method for manufacturing an electroformed timepiece component 1 has the following steps: the same first alloy including a first precious metal is selected to make both functional inserts 3 and an electroformed shell 2; these inserts 3 are made; an electroforming substrate having a complementary profile to the inner profile of the component 1 is formed in a second sacrificial material; the inserts are inserted into housings made on the substrate to form an equipped sacrificial substrate, which is provided with resists necessary to obtain a bare electroformed component by means of an electroforming process with deposition of material on the substrate, acting as a core to form this electroformed shell 2 and on each accessible surface of each insert 3 to secure the insert to the electroformed shell 2; all of these resists are removed; and the sacrificial substrate is destroyed.SELECTED DRAWING: Figure 5 |
