Method for decorating mechanical part

Abstract

The invention relates to a method for decorating at least one surface (4) to be decorated of a mechanical component, comprising the following steps: providing a mechanical component to be decorated, on which at least one decorative element (2a, 2b) is produced in accordance with a defined thickness and profile; depositing a masking layer (6) having a thickness at least equal to the thickness of the decorative element to be produced on the surface (4) of the mechanical component to be decorated; forming at least one opening (14a, 14b) in the masking layer, at least one opening coinciding with alocation on the surface (4) of the machine part to be decorated where the decorative element is to be produced, the contour of the opening being the same as the contour of the decorative element to be produced and defining a volume together with the machine part to be decorated; filling a volume defined by the masking layer and the surface to be decorated of the mechanical component with a filling material to produce a decorative element; and removing the masking layer (6).

Description

technical field [0001] The invention relates to a method for decorating machine parts. More specifically, the invention relates to a method for decorating mechanical parts used in the watch or jewelry field. Background technique [0002] Various methods are known in the prior art for producing raised decorations on the surface of mechanical parts such as dials or bezels. A number of these known methods consist in manufacturing the decorative elements separately from the machine part to be decorated and then fastening these decorative elements to the machine part for which they are intended. [0003] European patent application EP 2 370 865 A1 filed by Swatch Group Research & Development Ltd. discloses another method of decorating mechanical parts such as dials. The decoration method includes: [0004] – provision of mechanical parts to be decorated; [0005] - making a plate-type mask, the thickness of which is at least equal to the desired thickness of the decorative el...

Problems solved by technology

[0010] However, one disadvantage of the decoration method using a mask placed on the surface of the mechanical part to be decorated can still be seen, that is, the risk that the mask does not come into close contact with the surface of the mechanical part to be decorated cannot be ruled out, and when the filling is different In the case of molds with different types of molds, there is a risk of small leaks of the filling material on the surface of the mechanical parts, requiring the discarding of some of them

This is especially problematic when looking for dials to decorate timepieces, which are expensive mechanical components
