AI Technical Summary

⚠Technical Problem

Existing manufacturing processes for multicolored ceramic components are limited in creating complex patterns and lack control over ceramic colors, particularly in two-tone components.

⚗Method used

A manufacturing process involving partial sintering of ceramic parts with encapsulated pigments, followed by gradual heating and pressure, allows for the production of multicolored ceramic components with precise control over color arrangement and complex patterns, using techniques like laser machining and Spark Plasma Sintering.

🎯Benefits of technology

Enables the creation of multicolored ceramic components with controlled color placement and complex patterns, replicable and reproducible, while maintaining mechanical properties and finish similar to monochromatic ceramics.

Abstract

The invention relates to a method for manufacturing a ceramic watch or jewellery component (10), the component comprising a plurality of portions (1, 2) of different colours, the method comprising the following steps: (i) forming a first part (1a; 1f) made of a ceramic of a first colour and partially sintered by pressure sintering, in particular at a pressure of between 60 MPa and 80 MPa, (ii) adding a second part (2a; 2f) made of a ceramic of a second colour, (iii) complete sintering of the assembly.
