Title
(EN) METHOD FOR PRODUCING DECORATIVE PARTS
(FR) PROCEDE DE FABRICATION DE PIECES DECORATIVES
Abstract
(EN)
The invention relates to a method for producing a part (1) comprising a support (2) made of a non-electroconductive material, said support (2) being provided with at least one cavity (4) filled with an aesthetic element (3) made of an electroconductive material, said aesthetic element (3) forming a decoration on a face (2a) of the part (1), which is intended to be visible, the method comprising: a step of inlaying by pressing a preform intended to form the aesthetic element (3) into said at least one cavity (4) of the support (2); and a step of electrochemical surface treatment of the aesthetic element (3), said at least one cavity (4) leading to at least one area on a face (2b) of the part (1), which is intended not to be visible, in order to respectively form at least one contact point (4b) allowing the application of current during the surface treatment on the aesthetic element (3).
(FR)
L'invention concerne un procédé de fabrication d'une pièce (1) comprenant un support (2) réalisé dans un matériau non conducteur électrique, ledit support (2) étant muni d'au moins une creusure (4) remplie avec un élément esthétique (3) réalisé dans un matériau conducteur électrique, ledit élément esthétique (3) formant un décor sur une face (2a) de la pièce (1) destinée à être visible, le procédé comprenant : - une étape d'incrustation par pressage d'une préforme destinée à former l'élément esthétique (3) dans ladite au moins creusure (4) du support (2), - une étape de traitement de surface par voie électrochimique de l'élément esthétique (3), ladite au moins creusure (4) débouchant en un ou plusieurs endroits sur une face (2b) de la pièce (1) destinée à être non visible, pour former respectivement un ou plusieurs points de contact (4b) permettant d'amener du courant lors du traitement de surface sur l'élément esthétique (3).
