Exemplary embodiments described herein related to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated. |

Disclosed are systems and methods for mechanically reducing an amount of the skull material in a finished, molded part formed from amorphous alloy using an injection molding system. Skull material of molten amorphous alloy can be captured in a trap before molding such material. A cavity can be provided in the injection molding system to trap the skull material. For example, the cavity can be provided in the mold, the tip of the plunger rod, or in the transfer sleeve. Alternatively, mixing of molten amorphous alloy can be induced so that skull material is reduced before molding. A plunger and/or its tip can be used to induce mixing (e.g., systematic movement of plunger rod, or a shape of its tip). By minimizing the amount of skull material in the finished, molded part, the quality of the part is increased. |

A molding apparatus (30) is configured so as to form a molten metal holding space (41a) by dividing the inside of a connecting portion (41) into the molten metal holding space (41a) and a molten metal supply port-side space (41b) by closing an on-off valve (42), and pump up molten metal (5) from a molten metal furnace (50) into the molten metal holding space (41a) of the connecting portion (41) with a pump (40). Then a pressure of the molten metal (5) that has been pumped up into the molten metal holding space (41a) is reduced by a pressure-reducing portion, and the molten metal holding space (41a) inside the connecting portion (41) is communicated with a molten metal supply port (6) of an injection sleeve (2) by opening the on-off valve (42), and the molten metal (5), the pressure of which has been reduced in the molten metal holding space (41a), is supplied into the injection sleeve (2). |

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. |

A high-vacuum die-casting method includes an injecting step of moving a plunger in a sleeve so that a molten metal fed to the sleeve is pushed by the plunger to be injected into a cavity formed by a fixed mold and a movable mold, a cavity vacuumizing step of vacuum absorbing a gas in the cavity to discharge the vacuum-absorbed gas to the outside through a first path, and a sealed space vacuumizing step of vacuum absorbing a gas in a sealed space in which an eject plate and one ends of eject pins are arranged to discharge the vacuum-absorbed gas to the outside through a second path while the injecting step is performed. The sealed space vacuumizing step is started prior to the cavity vacuumizing step. |
