International Classification:

B22D 17/20
B22D 17/04
B22D 17/14

US Classification:

164493, 164113, 164 61, 164312, 164316

Abstract:

Various embodiments provide apparatus and methods for injection molding. In one embodiment, a constraining plunger may be configured in-line with an injection plunger to transfer a molten material from a melt zone and into a mold. The constraining and injection plungers are configured to constrain the molten material there-between while moving. The constrained molten material can be controlled to have an optimum surface area to volume ratio to provide minimized heat loss during the injection molding process. The system can be configured in a longitudinal direction (e.g., horizontally) for movement between the melt zone and mold along a longitudinal axis. A molded bulk amorphous object can be ejected from the mold.

B22D 41/01

US Classification:

164493, 266 44, 219672

Abstract:

Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.

US Classification:

164259, 164284, 164286

Abstract:

The embodiments described herein relate to methods and apparatus for counter-gravity formation of BMG-containing hollow parts. In one embodiment, the BMG-containing hollow parts may be formed by first feeding a molten metal alloy in a counter-gravity direction into a mold cavity to deposit the molten metal alloy on a surface of the mold cavity and then solidifying the deposited molten metal alloy.
