Various embodiments provide apparatus and methods for melting and introducing alloy feedstock for molding by using a hollow branch having a constraint mechanism therein. In one embodiment, a hollow branch can extend upward from a cold chamber that is substantially horizontally configured. The hollow branch including a constraint mechanism can be capable of containing an alloy feedstock for melting into the molten alloy in the hollow branch and introducing the molten alloy to the cold chamber for molding.

1. An apparatus comprising: a cold chamber substantially horizontally configured and connected to a mold configured for molding a molten alloy into a BMG part; anda hollow branch extending upward from a region of the cold chamber having an upward angle with a horizontal axis, the hollow branch comprising a constraint mechanism capable of containing both a solid alloy feedstock during melting into the molten alloy in the hollow branch and the molten alloy prior to introducing the molten alloy to the cold chamber for molding;wherein an interface between the constraint mechanism and the molten alloy is substantially non-wetting to the molten alloy, wherein the constraint mechanism is configured to be cooled by a coolant to cool the constraint mechanism to regulate a temperature of the interface. 2. The apparatus of claim 1, further comprising a heating component configured associated with the hollow branch to provide a melt zone along the hollow branch. 3. The apparatus of claim 1, further comprising a plunger configured to push the molten alloy from the cold chamber into the mold. 4. The apparatus of claim 1, wherein the constraint mechanism comprises a surface having a regulated surface temperature. 5. The apparatus of claim 1, wherein the constraint mechanism comprises a plurality of fingers, a constriction, a step, a plate, a rod, a detent, or their combinations, extended from a side of a wall of the hollow branch and configured within the hollow branch. 6. The apparatus of claim 1, wherein the constraint mechanism provides a narrowed horizontal opening within the hollow branch to block the alloy feedstock pass through. 7. The apparatus of claim 1, wherein the constraint mechanism is retractable or rotatable to adjust an opening within the hollow branch. 8. The apparatus of claim 1, wherein the apparatus comprises a die-casting apparatus that does not include a melt crucible. 9. The apparatus of claim 1, wherein the cold chamber is shielded from a heating component associated with the hollow branch. 10. The apparatus of claim 1, wherein the coolant is a fluid capable of providing cooling effect. 11. The apparatus of claim 10, wherein the fluid comprises water, gas or oil. 12. An apparatus comprising: a cold chamber substantially horizontally configured and connected to a mold configured for molding a molten alloy into a BMG part; anda hollow branch extending upward from a region of the cold chamber having an upward angle with a horizontal axis, the hollow branch comprising a constraint mechanism capable of containing both a solid alloy feedstock during melting into the molten alloy in the hollow branch and the molten alloy prior to introducing the molten alloy to the cold chamber for molding;wherein an interface between the constraint mechanism and the molten alloy is substantially non-wetting to the molten alloy, wherein the constraint mechanism comprises a cooling channel to regulate a temperature of the interface. 13. The apparatus of claim 12, further comprising a heating component configured associated with the hollow branch to provide a melt zone along the hollow branch. 14. The apparatus of claim 12, further comprising a plunger configured to push the molten alloy from the cold chamber into the mold. 15. The apparatus of claim 12, wherein the constraint mechanism comprises a surface having a regulated surface temperature. 16. The apparatus of claim 12, wherein the constraint mechanism comprises a plurality of fingers, a constriction, a step, a plate, a rod, a detent, or their combinations, extended from a side of a wall of the hollow branch and configured within the hollow branch. 17. The apparatus of claim 12, wherein the constraint mechanism provides a narrowed horizontal opening within the hollow branch to block the alloy feedstock pass through. 18. The apparatus of claim 12, wherein the constraint mechanism is retractable or rotatable to adjust an opening within the hollow branch. 19. The apparatus of claim 12, wherein the apparatus comprises a die-casting apparatus that does not include a melt crucible. 20. The apparatus of claim 12, wherein the cold chamber is shielded from a heating component associated with the hollow branch.
