摘要： A method of forming a gating fixture for a lost wax casting process includes determining an optimal orientation of a gate in relation to a part, and forming a fixture that can repeatably be used to consistently locate the gate relative to the part. In one example, stereolithography is used to form the fixture.

摘要： 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. A non-soluble wax is then introduced into the first mold for completely surrounding the soluble wax core insert. The non-soluble wax then hardens and the entire unit is removed from the first mold, including the soluble wax core. The core is then removed by a suitable water soluble or chemical mechanism. The remaining wax model contains a hollow core running along a substantial portion of the arcuate length of the shank; the shank has a finger facing surface formed with a plurality of openings which lead to said core. The wax model is then cast in order to form the inventive ring design.

摘要： A mold is provided for enabling casting of single crystal metallic articles including a part-defining cavity, a sorter passage positioned vertically beneath and in fluid communication with the part-defining cavity, and a seed cavity positioned vertically beneath and in fluid communication with the sorter passage. The sorter passage includes a shape suitable for encouraging a single crystal structure in solidifying molten metal. Additionally, a portion of the mold between the sorter passage and the part-defining cavity includes a notch for facilitating breakage of a cast article proximate the notch during thermal stress build-up, so as to prevent mold breakage or the inclusion of part defects.
