Process for manufacturing a dial

A process for manufacturing a watch dial comprising at least one pattern on a visible face of the dial, said process comprising:

• a step of designing a support plate comprising a dial blank, said step comprising producing several through holes in a thickness of a body of the support plate, said holes delimiting in the support plate an edge of the dial blank, and
• a step of producing at least one pattern on the visible face of said dial blank during which the following is performed:
• an arrangement step of arranging said support plate comprising the dial blank in a mould formed by the reversible assembly of a first part and a second part, said arrangement step comprising a sub-step of forming at least one cavity in said mould by associating the first part including at least one impression with the visible face of the dial blank;
• a construction step of constructing a blank of each of the at least one pattern on the visible face of the dial blank, said construction step comprising a sub-step of over-moulding by injecting an injectable material into the cavity via a through opening arranged in said dial blank provided with an entry orifice of said cavity;
• a finalization step of finalizing the blank of the pattern comprising a sub-step of removing said mould from the support plate comprising the dial blank provided with the blank of the at least one pattern over-moulded on the visible face thereof, wherein said removal sub-step comprises breaking the injectable material at an injection point connecting said dial blank to the second part, wherein said injectable material at said injection point is broken such that a base of a foot formed by the at least one pattern is level with a hidden face of the dial blank.
