Methods and systems for integrally trapping a glass insert in a metal bezel
Methods and apparatus for creating an overall assembly formed from a transparent member and a metal member are disclosed. According to one aspect of the present invention, a method includes positioning a transparent member in a mold configured for insertion molding, and providing a liquid metal into the mold. The method also includes hardening the liquid metal in the mold. Hardening the liquid metal includes binding the metal to the transparent member to create the integral assembly.
1. An apparatus comprising:
an insert piece, the insert piece including a first channel;
a metal member comprising an amorphous alloy, the metal member including a second channel; and
a compliant material, the compliant material being arranged in the first channel and the second channel, wherein the compliant material couples the insert piece to the metal member.
2. The apparatus of claim 1 wherein the insert piece comprises glass, ceramic or plastic and the compliant member comprises a material selected from a group including a silicon, a rubber, a thermoplastic elastomer, poron, and any combination thereof.
3. The apparatus of claim 1 , wherein the amorphous alloy maintains a liquid state at a temperature that is not sufficient to cause significant softening of the insert piece.
4. The apparatus of claim 1 , wherein the insert piece is transparent.
5. An electronic device comprising:
an assembly, the assembly comprising a metal member and an insert piece with substantially no voids disposed therebetween, the metal member and the insert piece cooperating to define an exterior portion of the electronic device; and
at least one electronic element, the at least one electronic element being arranged to be at least partially covered by the assembly, wherein the metal member comprises an amorphous alloy; and wherein a thermal expansion rate of the metal member is approximately equal to a thermal expansion rate of the insert piece.
6. The electronic device of claim 5 wherein the insert piece comprises glass, ceramic or plastic.
7. The electronic device of claim 6 wherein the metal member comprises a bezel.
8. The electronic device of claim 5 wherein the electronic device comprises a cellular phone device.
9. The electronic device of claim 5 , wherein the metal member forms all or some portion of an entire housing of the electronic device.
10. The electronic device of claim 5 , wherein the electronic device comprises an electrical and/or communication component.
11. The electronic device of claim 5 , wherein the amorphous alloy maintains a liquid state at a temperature that is not sufficient to cause significant softening of the insert piece.
12. The electronic device of claim 5 , further comprising at least one layer of a compliant material at an edge of the insert piece.
13. The electronic device of claim 12 wherein the insert piece includes a first channel and the metal member includes a second channel, and a gasket is positioned at least partially in the first channel and at least partially in the second channel.
14. The electronic device of claim 5 , wherein the electronic device comprises a computer, a laptop, a handheld computing device, a media player, a phone, a remote control, or any combination thereof.
15. The electronic device of claim 5 , wherein the insert piece is transparent.
16. An integral assembly comprising: an insert piece and a metal member; wherein the metal member comprises an amorphous alloy and binds to the insert piece to create the integral assembly; and wherein a thermal expansion rate of the metal member is approximately equal to a thermal expansion rate of the insert piece.
17. The integral assembly of claim 16 , wherein the insert piece is transparent.
18. An apparatus for forming an integral assembly comprising an insert piece and a metal member; wherein the metal member comprises an amorphous alloy, the apparatus comprising:
an arm to position the insert piece in a mold; and
a metal injector to provide the amorphous alloy around the insert piece in the mold to form the metal member such that the metal member binds to the insert piece to create the integral assembly.
19. The apparatus of claim 18 wherein the apparatus is configured to maintain the amorphous alloy in a liquid state at a temperature that is not sufficient to cause significant softening of the insert piece.
20. The apparatus of claim 18 wherein the apparatus is configured to center the insert piece relative to the metal member.
21. The apparatus of claim 18 wherein the apparatus comprises a metal injection molding (MIM) equipment.
22. The apparatus of claim 21 , wherein the MIM equipment is configured to shrink or bake the amorphous alloy around the insert piece.
23. The apparatus of claim 18 , wherein the insert piece is transparent.
