Patent number: 7637123Abstract: There is provided a method or process for fabricating a hollow jewelry article which is hollowed or bored out. In accordance with this process, a metal ring model is prepared comprising a solid shank and a metal plate supported along the internal perimeter of the shank by means of a series of spokes extending from the shank. A first metal mold is produced from the metal ring model having the external shape of the jewelry article to be manufactured. From this mold, a wax model of the jewelry article is produced which is first filed down and then cast in order to form a metal model of a core insert; the core insert, like the ring model, has a plate disposed along the perimeter of the shank. This core insert is used to produce a second metal mold. This second mold may then be used repeatedly in order to form a soluble wax core insert model which is then inserted into the cavity of the first mold in order to define the hollow region of the article.Type: GrantFiled: March 20, 2007Date of Patent: December 29, 2009Assignee: Unimold Cast Ltd.Inventors: Ervant Hashimian, Garabed Ayvazian
