(EN) FORMING OF A ONE-PIECE TRANSPARENT TIMEPIECE COMPONENT
(FR) FORMAGE DE COMPOSANT D'HORLOGERIE TRANSPARENT MONOBLOC
Abrégé
(EN) The invention relates to a method for forming a transparent timepiece component (1) comprising upper (2) and lower (3) surfaces, in which: a polymerisable transparent material (5) is selected; a flexible female mould (9) is applied to a plate (15), wherein one contact surface (10) of the mould is the negative of the above-mentioned lower surface (3) and is bordered by a rim (11), said mould (9) comprising a capillary network (14); a cavity (17) is formed by means of the sealed abutment of the rim (11) against a plate (6) of which one contact surface (7) is the negative of the above-mentioned upper surface (2); the cavity (17) is filled with material (5) that is injected through the capillary network (14); the material (5) is polymerised in order to obtain a rigid component (1); and the component (1) is detached from the plates by deforming the flexible mould (9). Hardness is enhanced by insulating the component (1) against UV.
(FR) Formage de composant d'horlogerie transparent monobloc Procédé de formage d'un composant d'horlogerie (1) transparent, comportant des surfaces supérieure (2) et inférieure (3): - on choisit un matériau (5) transparent et polymérisable; - on applique sur une plaque (15) un moule femelle souple (9), dont une surface de contact (10) est le négatif de la surface inférieure (3), bordée par un rebord (11), ce moule (9) comportant un réseau capillaire (14); - on délimite une cavité (17) par juxtaposition étanche du rebord (11) avec une plaque (6) dont une surface de contact (7) est le négatif de la surface supérieure (2), - on injecte au travers du réseau capillaire (14) le matériau (5), pour remplir la cavité (17); - on polymérise le matériau (5) pour l'obtention d'un composant (1) rigide; - on détache le composant (1) des plaques par déformation dudit moule souple (9). On augmente la dureté en insolant ledit composant (1) aux UV.
