COLD CHAMBER DIE CASTING WITH MELT CRUCIBLE UNDER VACUUM ENVIRONMENT

摘要

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.

主权项

1. A casting method comprising:
obtaining a casting system comprising a transfer zone chamber, the transfer zone chamber comprising at least a portion of a first chamber and at least a portion of the casting machine, the first chamber comprising at least one vessel to contain a molten material for casting in the casting machine; adjusting a chamber environment of the first chamber; forming the molten material in the at least one vessel of the first chamber; transferring the molten material in the transfer zone chamber from the first chamber into the casting machine; and substantially independently maintaining the chamber environment of the first chamber while transferring the molten material.
