Abstract
A method for manufacturing metallic horological components includes the steps of forming a LIGA-UV type method a multi-level photosensitive resin mould and of galvanically depositing a layer of at least one metal using at least two conductive layers to form a block substantially reaching the top surface of the photosensitive resin.
Claims14
A method for manufacturing at least one horological component comprising the following steps:
- a) providing a substrate, depositing a first electrically conductive layer thereon, and applying a layer of photosensitive resin;
- b) performing hot stamping via a buffer of the layer of photosensitive resin by pressing the buffer up to a predefined distance from the substrate to form a shaped layer of photosensitive resin;
- c) irradiating the shaped layer of photosensitive resin through a mask defining at least a first level of the component and dissolving non-irradiated zones of the shaped layer of photosensitive resin to reveal in places the first electrically conductive layer and form a mould comprising a first and a second level;
- d) depositing a metallic layer by electroforming in the mould from the first electrically conductive layer to form the component, the metallic layer substantially reaching a top surface of the shaped layer of photosensitive resin;
- and
- e) successively removing the substrate, the first electrically conductive layer and the shaped layer of photosensitive resin to release the component.
