Systems and processes for forming molds such as nickel molds

Номер: US20130048502A1
Автор: Christina Yuan Ling Tan, Isabel Rodriguez, Jarrett Dumond, Kambiz Ansari, Yee Chong Loke
Принадлежит: Agency for Science Technology and Research Singapore

For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.

The invention makes it possible to produce very thin ceramic blanks as a precursor for ceramic discs, for example for use as faces in wrist watches. On the other hand, the production of metal blanks for use in CAD/CAM machines is possible with the invention. Both methods are based on depositing the material from a slurry or slip by electrophoresis. The essence of the invention is the isolation of the peripheral region of the precipitation electrodes that is produced by a non-conducting frame. This allows the precipitated mass to be easily lifted off from the precipitation electrode. The subsequent sintering with a possibly proceeding machining operation allows precision articles to be produced. 1256.
