#CMT# #/CMT# The process comprises preparing a sacrificial mold (14) corresponding to the shape of a decorative element (10), depositing a layer of metallic material covering the entire cast, eliminating the sacrificial mold to form the decorative element comprising a hollow body, forming two holes (10a) for the passage of a fastener of the decorative element, and optionally surface treating the obtained decorative element. The decorative element is designed to place on a joint between two links. The hollow body is filled by an epoxy resin. The sacrificial mold is prepared by injection molding. #CMT# : #/CMT# The process comprises preparing a sacrificial mold (14) corresponding to the shape of a decorative element (10), depositing a layer of metallic material covering the entire cast, eliminating the sacrificial mold to form the decorative element comprising a hollow body, forming two holes (10a) for the passage of a fastener of the decorative element, and optionally surface treating the obtained decorative element. The decorative element is designed to place on a joint between two links. The hollow body is filled by an epoxy resin. The sacrificial mold is prepared by injection molding of a plastic material. The deposition of a layer of metallic material is carried out by electroplating. The step of removing the sacrificial mold is carried out by heating at a temperature greater than the decomposition temperature of the plastic material. An independent claim is included for a decorative element. #CMT#USE : #/CMT# The process is useful for fabricating a decorative element for a watchband comprising articulated links. #CMT#ADVANTAGE : #/CMT# The process is capable of economically and easily manufacturing a stable and reproducible decorative element with reduced weight, high mechanical strength, high toughness and improved optical quality and/or aesthetics, provides sufficient hardness to prevent scratching or accidental shock to the material, and minimizes internal stress of the materials. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of a decorative element. 10 : Decorative element 10a : Holes 14 : Sacrificial mold. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The metallic material is gold and silver. |
