    Abstract: 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.

    Abstract: Described herein is a feedstock comprising BMG. The feedstock has a surface with an average roughness of at least 200 microns. Also described herein is a feedstock comprising BMG. The feedstock, when supported on a support during a melting process of the feedstock, has a contact area between the feedstock and the support up to 50% of a total area of the support. These feedstocks can be made by molding ingots of BMG into a mole with surface patterns, enclosing one or more cores into a sheath with a roughened surface, chemical etching, laser ablating, machining, grinding, sandblasting, or shot peening. The feedstocks can be used as starting materials in an injection molding process.

    Abstract: Exemplary embodiments described herein relate 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.
