Abstract:
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.
Abstract:
A metal enclosure has a surface region which is coated with cladding material using a laser cladding process. The metal enclosure can form at least a portion of an electronic device housing. All or part of one or more surfaces of the enclosure can be coated with cladding material. The coating of cladding material can be varied at selective regions of the enclosure to provide different structural properties at these regions. The coating of cladding material can be varied at selective regions to provide contrast in cosmetic appearance.
Abstract:
Provided in one embodiment is a method of joining one or more articles together using pressurized fluid to deform a bulk-solidifying amorphous alloy material and form a mechanical interlock between the respective surfaces joined together.
Abstract:
Techniques or processes for providing markings on products are disclosed. In one embodiment, the products have housings and the markings are to be provided on the housings. For example, a housing for a particular product can include an outer housing surface and the markings can be provided on the outer housing surface so as to be visible from the outside of the housing. The markings are able to be interferometric colors and/or black.
Abstract:
A housing of an electronic device includes a substrate defining an external surface and internal surface of the housing, at least one sidewall extending from the substrate, and abrasion-resistant members at least partly embedded in the substrate and extending beyond the external surface. The abrasion-resistant members may be formed from metal or ceramic. The substrate comprises a moldable matrix. The abrasion-resistant members are harder than the moldable matrix.
Abstract:
A metal matrix composite using as one of the components a precious metal is described. In one embodiment, the precious metal takes the form of gold and the metal matrix composite has a gold mass fraction in accordance with 18 k. The metal matrix composite can be formed by blending a precious metal ( e.g. , gold) powder and a ceramic powder, forming a mixture that is then compressed within a die having a near net shape of the metal matrix composite. The compressed mixture in the die is then heated to sinter the precious metal and ceramic powder. Other techniques for forming the precious metal matrix composite using HIP, and a diamond powder are also disclosed.
Abstract:
An apparatus with a vessel (20), a first induction source (30), and a second induction source (32) in the melt zone (12). The first induction source (30) is used to melt the material received in the vessel (20). The second induction source (32) is used to contain the material in a meltable form within the vessel (20) during melting. The coils (26) of each of the first and second induction sources (30,32) can be arranged such that they intertwine in an alternate fashion or that they are in sets in a series. The coils (26) of the sources (30,32) can also sequentially receive power such that the material is moved through the ejection path after melting and into an adjacent mold. The vessel (20) can be positioned along a horizontal axis (X). The apparatus can be used to melt and mold amorphous alloys; for example.
Abstract:
Disclosed herein are consumer electronics housings made from bulk-solidifying amorphous alloy materials having a ductile coating applied to all or a portion of the bulk-solidifying amorphous alloy. Also disclosed are methods of making consumer electronic housings from bulk- solidifying amorphous alloy materials such that at least a portion of the bulk-solidifying amorphous alloy housing is coated with a ductile cladding material.
Abstract:
Methods and apparatus for creating an integral assembly formed from a transparent member and a housing formed at least in part of a bulk-solidifying amorphous alloy. The methods and systems create integral transparent member and amorphous metal alloy-containing parts using thermoplastic molding techniques in which the amorphous metal is molded to the transparent member in a thermoplastic, not liquid, state.
Abstract:
Described herein is a method of producing an alloy. The method includes pouring a stream of molten mixture of component elements of the alloy, separating the stream into discrete pieces, solidifying the discrete pieces by cooling before the discrete pieces contact any liquid or solid. Also described herein is another method of producing an alloy. This method includes pouring and solidifying a stream of molten mixture of component elements of the alloy into a rod or pulling a rod from a molten mixture of component elements of the alloy, before the rod contacts any liquid or solid, separating the rod into discrete pieces. An apparatus suitable for carrying out the methods above can include a container from which the molten stream is poured or the solid rod extends, one or more coil, conductive plates, a laser source, or an electron beam source arranged around the molten stream or the solid rod and configured to separate the molten stream or the solid rod into discrete pieces.
