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.

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.

A composite structure includes a matrix material having an intrinsic strain-to-failure rating in tension and a reinforcing material embedded in the bulk material. The reinforcing material is pre-stressed by a tensile force acting along one direction. The embedded reinforcing material interacts with the matrix material to place the composite structure into a compressive state. The compressive state provides an increased strain-to-failure rating in tension of the composite structure along a direction that is greater than the intrinsic strain-to-failure rating in tension of the matrix material along that direction. At least one of the matrix material and the reinforcing material is a bulk amorphous alloy (BAA). The reinforcing material can be a fiber or wire.

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.

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).

Injection molding and casting of materials using a vertical injection molding system

Номер: WO2013158069A1
Автор: Christopher D. Prest, Dermot J. Stratton, Joseph C. Poole, Matthew S. Scott
Принадлежит: Apple Inc.

An injection molding system and methods for improving performance of the same. The system includes a plunger rod and a melt zone that are provided in-line and on a vertical axis. The plunger rod is moved in a vertical direction through the melt zone to move molten material into a mold. The injection molding system can perform the melting and molding processes under a vacuum. Skull formation in molten material is reduced by providing an RF transparent sleeve in the melt zone and/or a skull trapping portion adjacent an inlet of the mold. It can also be controlled based on the melting unit. Vacuum evacuation can be reduced during part ejection by using a plunger seal, so that evacuation time between cycles is reduced.

Electronic devices with adjustable-appearance housing structures

Номер: US11175700B1
Автор: Christopher D. Jones, Christopher D. Prest, James R. Wilson, Joseph C. Poole, Marta M. GIACHINO, Matthew S. Rogers
Принадлежит: Apple Inc

An electronic device may have a display for displaying images. The display may be coupled to a housing on a front face of the device. The housing may have a transparent portion on an opposing rear face of the device. The electronic device may have structures with an adjustable appearance. The adjustable-appearance structures may include a mask with openings or other mask elements and a corresponding overlapped patterned layer containing an array of visual elements. The visual elements may have different appearances, so that movement of the mask relative to the patterned layer changes the appearance of the adjustable-appearance structures. The state of the adjustable-appearance structure may be changed during use of the device by a user or may be adjusted then fixed during manufacturing.
