Patent number: 9873151Abstract: Disclosed are embodiments of a vessel configured to contain a secondary magnetic induction field therein for melting materials, and methods of use thereof. The vessel can be used in an injection molding apparatus having an induction coil positioned adjacent to the vessel. The vessel can have a tubular body configured to substantially surround and receive a plunger tip. Longitudinal slots or gaps extend through the thickness of the body to allow and/or direct eddy currents into the vessel during application of an RF induction field from the coil. The body also includes temperature regulating lines configured to flow a liquid within. The temperature regulating lines can be provided to run longitudinally within the wall(s) of the body between its inner bore and outer surface(s). A flange may be provided at one end of the body to secure the body within an injection molding apparatus.Type: GrantFiled: December 16, 2014Date of Patent: January 23, 2018Assignee: Crucible Intellectual Property, LLCInventors: Sean Timothy O'Keeffe, Adam A. Verreault, Glenton Jelbert, Michael Deming

Patent number: 9733017Abstract: Described herein is a crucible with a rod fused thereon to optimize pouring of molten material, and method of using the same. The crucible has a body configured for receipt of an amorphous alloy material in a vertical direction, and the rod extends in a horizontal direction from the body. The body of the crucible and the rod are formed from silica or quartz. The rod may be fused to the body of the crucible and provided off a center axis so that pouring molten material is improved when the crucible is rotated.Type: GrantFiled: December 16, 2014Date of Patent: August 15, 2017Assignee: CRUCIBLE INTELLECTUAL PROPERTY, LLC.Inventors: Sean Timothy O'Keeffe, Adam A. Verreault, Michael Deming, Glenton Jelbert, Stephanie O'Keeffe, Adrian Lopez

Patent number: 9630246Abstract: Disclosed is an apparatus comprising at least one gate and a vessel, the gate being configured to move between a first position to restrict entry into an ejection path of the vessel and contain a material in a meltable form within the vessel during melting of the material, and a second position to allow movement of the material in a molten form through the ejection path. The gate can move linearly or rotate between its first and second positions, for example. The apparatus is configured to melt the material and the at least one gate is configured to allow the apparatus to be maintained under vacuum during the melting of the material. Melting can be performed using an induction source. The apparatus may also include a mold configured to receive molten material and for molding a molded part, such as a bulk amorphous alloy part.Type: GrantFiled: October 14, 2011Date of Patent: April 25, 2017Assignee: Crucible Intellectual Property, LLCInventors: Quoc Tran Pham, Michael Deming, Theodore A. Waniuk, Sean O'Keeffe

Patent number: 9544949Abstract: Vessels used for melting material to be injection molded to form a part are described. One vessel has a body formed from a plurality of elongate segments configured to be electrically isolated from each other and with a melting portion for melting meltable material therein. Material can be provided between adjacent segments. An induction coil can be used to melt the material in the body. Other vessels have a body with an embedded induction coil therein. The embedded coil can be configured to surround the melting portion, or can be positioned below and/or adjacent the melting portion, so that meltable material is melted. The vessels can be used to melt amorphous alloys, for example.Type: GrantFiled: January 23, 2012Date of Patent: January 10, 2017Assignee: Apple Inc.Inventors: Quoc Tran Pham, Michael Deming, Theodore A. Waniuk, Sean Timothy O'Keeffe, Joseph Stevick

Publication number: 20160067766Abstract: Described herein is a method of forming a 3D investment mold using a layer-by-layer construction (3D printing). The mold is configured for receipt of a molten alloy having a composition configured to form a bulk metallic glass (BMG) on cooling. The mold has a hollow interior between inner and outer walls. The hollow interior receives the molten alloy for molding it between the inner and outer walls of the mold. A method of casting using the 3D investment mold is also disclosed, which may include filling the mold with molten alloy, removing bubbles, quenching the molten alloy in the mold, and then removing the mold.Type: ApplicationFiled: December 16, 2014Publication date: March 10, 2016Inventors: Adam A.
