Method for manufacturing by photolithography a resin multilayer mould (') including a cavity (′) provided with an inlet (′) for the manufacture of a horological component, including producing at least two resin layers of the mould (′), by producing a first resin layer (C; C′) having a first through-opening or open opening (′) oriented in the direction of the inlet (′) of the mould to delimit a first volume of the cavity (′) of the mould (′), and producing a second resin layer (C; C′) including a rigid film and having a second through-opening (′) that delimits a second volume of the cavity (′) of the mould (′) and is at least partly superposed on the first through-opening or open opening (′), the second resin layer partly covering that same first through-opening or open opening (′).

Manufacture of a horology component

Method for manufacturing a horology component, including manufacturing (E) a first structure () from a first photosensitive resin () having at least one layer of photosensitive resin having a first pattern obtained by polymerizing the first photosensitive resin by irradiation through at least one mask (), then developing the first photosensitive resin; and transforming (E) the first structure () into a second structure () by structuring at least one surface of the first structure by the addition of a second photosensitive resin () to the at least one surface, the second structure () being intended to at least partially form a manufacturing mold for the horology component.

Method for manufacturing a horology component

Method for manufacturing a master pattern for a mold for a horology component, wherein the method includes manufacturing a first structure from a first photosensitive resin comprising at least one layer of photosensitive resin comprising a first pattern obtained by polymerizing the first photosensitive resin by irradiation through at least one mask, then developing the first photosensitive resin; and transforming the first structure into a second structure by structuring at least one surface of the first structure by the addition of a second photosensitive resin to the at least one surface.
