• Electroforming — Wikipedia Republished // WIKI 2

    Electroforming is a metal forming process that forms parts through electrodeposition on a model, known in the industry as a mandrel. Conductive (metallic) mandrels are passivated (chemically) to preclude 'plating' and thereby to allow subsequent separation of the finished electroform. Non-conductive (glass, silicon, plastic) mandrels require the deposition of a conductive layer prior to ...

    PFM's can be thought of as a hybrid between all-metal and all-ceramic dental crowns because they're made out of both materials. A metal alloy is used to create a thin thimble-like cap ("substructure") that fits snugly over the tooth.; Porcelain is then fused over the substructure to form the shape of the crown and give it a white tooth-like appearance.
