Title:
COMPOSITE MANDREL
Document Type and Number:
WIPO Patent Application WO2002072922
Kind Code:
A3
Abstract:
A method of forming a mandrel for electrodeposition by forming a shaped solid shell on a model, optionally separating the shell from the model, casting a backing mass directly or indirectly against the shell, causing the backing mass to solidify and bond to the shell, if not already separated from the model body, separating the shell from the model body to expose the plating face of the backing mass-bonded shell, optionally working, for example by milling, grinding, polishing, etching or machining, the plating face of the backing mass-bonded shell to adjust the shaping thereof, and if not already so activated, activating at least one region of the plating face of the backing mass-bonded shell to receive build-up of plating metal by electrodeposition. A composite mandrel of this type is also disclosed.
