  • the Galvanoform In order that the skins formed in the Galvanoform can be removed from the Galvanoform without damage, it is known to provide the Galvanoform with a non-stick coating prior to the production of the skins. Furthermore, the gloss level of the skin can be ensured by means of a non-stick coating. This non-stick coating is applied according to the known prior art by spraying or brushing subsequently on the finished Galvanoform.
  • the object of the invention is therefore to provide a method which makes it possible to produce a Galvanoform with a reproducible non-stick coating with a good resolution.
  • Another object of the invention is to provide a coated mold.
  • the method according to the invention for coating a galvanoform with an anti-adhesion layer comprises the steps of: a) coating the surface of a mother mold with an anti-adhesion layer by a first electroplating process; b) producing a Galvanoform in the coated mother mold by a second Galvanoprozeß, wherein the materials of non-stick layer and Galvanoform to be produced are selected such that they together form a firm connection to undergo c) removing the Galvanoform with the non-stick layer firmly attached thereto.
  • non-stick layer is produced chemically in the dip bath by means of a galvanic process makes it possible, in particular, to transfer fine structures from the mother mold directly to an anti-adhesive layer, since the surface of the mother mold and the surface of the coated mold forming the surface are Adjacent non-stick layer. Furthermore, such structures can be imaged in a non-stick layer having a uniform layer thickness.

Abstract

L'invention concerne un procédé de formation d'un moule de galvanoplastie revêtu d'une couche antiadhérente ainsi qu'un moule revêtu. Le procédé selon l'invention de revêtement d'un moule de galvanoplastie (3) doté d'une couche antiadhérente contient les étapes qui consistent à: a) revêtir la surface d'un moule mère (1) d'une couche antiadhérente (2) par une première opération de galvanisation, b) par une deuxième opération de galvanisation, préparer un moule de galvanoplastie (3) dans le moule mère (1) revêtu, les matériaux de la couche antiadhérente (2) et du moule de galvanoplastie (3) à former étant sélectionnés de manière à entrer en liaison ferme l'un avec l'autre, et c) enlever le moule de galvanoplastie (3) avec la couche antiadhérente qui y est fermement reliée. Le procédé selon l'invention permet également de transférer avec grande précision sur la surface de la couche antiadhérente de fines structures de la surface d'un moule mère.
