Abstract:
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.
Abstract:
An investment-diecasting mold has a thin inner investment casting ceramic layer surrounded by a thicker outer metallic diecasting material. The two layers, inner ceramic and outer metallic, provide a hybrid mold for the fabrication of near-to-net or near net shape amorphous alloy composed parts. The inner ceramic layer being appropriate for thermoconductivity and the casting of intricately designed parts, and the outer metallic diecasting mold for support of the inner investment casting layer and as a heat sink for quench of the molten amorphous alloys during use.
Abstract:
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.
Abstract:
Disclosed are embodiments of a temperature regulated vessel and a fluid delivery device, and methods of use thereof. The vessel can be used in an injection molding apparatus and include one or more temperature regulating lines configured to flow a fluid or liquid within the body (e.g., to heat a cold device). The fluid delivery device is mounted in the apparatus and has a collar with an opening extending therethrough to sealingly mate with the vessel. A delivery channel is provided within the collar for directing an input flow of fluid into the vessel. An exit channel can also be provided within the collar for directing an output flow of the fluid from the vessel.

Abstract:
An embodiment relates to a method comprising overmolding a bulk-solidifying amorphous alloy on a preform of another material than the bulk-solidifying amorphous alloy to form a bulk-solidifying amorphous alloy overmolded preform. Another embodiment relates to an article comprising an overmolded shell comprising the bulk-solidifying amorphous alloy on a preform of another material than the bulk-solidifying amorphous alloy. The preform could be made of a crystalline or amorphous metal or alloy such as aluminum, stainless steel, copper or beryllium.

Abstract:
Various embodiments provide an apparatus and methods for containing the molten materials within a melt zone during melting. The apparatus may include a vessel configured to receive a material for melting therein and an induction coil with unevenly spaced turns along its length. Induction coil can have a series of turns acting as a first (e.g., load) induction coil and a series of turns acting as a second (e.g., containment) induction coil. The material in the vessel can be heated and contained by the separated turns of the induction coil. A plunger can also assist in containing material during melting. Once the desired temperature is achieved and maintained for the molten material, operation of the induction coil can be stopped and the molten material can be ejected from the vessel into a mold using the plunger.
