Abstract (en)
[origin: US2016017509A1] Method for manufacturing an electroformed timepiece component: the same first alloy including a first precious metal is selected to make both functional inserts and an electroformed shell; these inserts are made; an electroforming substrate having a complementary profile to the inner profile of this component is formed in a second sacrificial material; these inserts are inserted into housings made on this substrate, to form an equipped sacrificial substrate, which is provided with the resists necessary to obtain, by means of an electroforming process, a bare electroformed component, with deposition of material on this substrate, acting as a core to form this electroformed shell, and on each accessible surface of each insert to secure the insert to this electroformed shell; then this sacrificial substrate is destroyed and all of these resists are removed.
