Problems solved by technology
[0010] However, a disadvantage of the decoration method using a mask placed on the surface to be decorated of the mechanical part can be seen in the fact that the risk of the mask not being in close contact with the surface to be decorated of the mechanical part cannot be ruled out, and when When filling different moulds, there is a risk that some of the filling material will leak on the surface of the mechanical parts, which requires discarding some of these mechanical parts
This is especially problematic when one wishes to decorate a dial for a timepiece, which is an expensive mechanical component

Embodiment Construction
[0061] The present invention derived from the following general invention, including the formation of a decorative element on the surface of the mechanical member to be decoled, said mechanical components, particularly a dial, more generally an external element such as a lap, Middleware or even a chain link, as well as jewelry. In order to achieve this, the present invention discloses a mask that deposits a sacrificial type on the surface of the mechanical member to be decoled, that is, a mask to be removed at the end of the operation of the decorative mechanical member. Once the mask has been deposited into the surface of the mechanical member to be decoled, structured to produce a first cavity therein, the first chamber, which is filled with a material in which the decorative element is to be produced, the top and decoration of the mask. The surface experience of the component is machined and potential trim, which is usually removed by etching in a chemical bath. In order to fur...

Abstract
The invention relates to a method for decorating a surface (4) to be decorated of a mechanical component, comprising: acquiring the mechanical component to be decorated, on which at least one decorative element (2a, 2b) is to be produced according to a predetermined thickness and profile; depositing a mask layer (6) on the at least one surface to be decorated, the thickness of the mask layer being at least equal to the thickness of the at least one decorative element to be manufactured; producing at least one first cavity (14a, 14b) in the mask layer, the first cavity coinciding with the location on the at least one surface to be decorated at which the at least one decorative element is to be produced, and the cavity having a contour corresponding to the contour of the decorative element to be produced and defining a volume with the surface to be decorated; depositing a bonding layer made of a conductive material on top of the mask layer and on the surface to be decorated in the position where the cavity has been formed to promote bonding of the decorative element; filling a volume delimited by the mask layer and the surface to be decorated of the mechanical component with a filling material in which the decorative element is intended to be manufactured; and removing the mask layer.
Description
Technical field [0001] The present invention relates to a method of decorating a mechanical component. More specifically, the present invention relates to a method of at least one of a mechanical component to be decoled in a decorative clock or an jewelry. Background technique [0002] A variety of methods for generating raised decoration on the surface of a mechanical component such as a watch dial or a lap is known in the prior art. Some of these known methods include separately fabricating the decorative elements separately from the mechanical components to be decorated, and then fastening the decorative elements to the mechanical components thereof. [0003] Another method for decorating a mechanical component such as a dial is known from the European Patent Application Submitted by Swatch Group Research andDevelopment Ltd. EP2370865A1. This decorative method includes: [0004] - Get the mechanical parts to be decorated; [0005] - Manufacture of a plate type mask whose thick...
