1. A vertical injection machine for injecting liquid metal comprising:a metering chamber; a liquid metal adjustment device comprising at least one recycle port located in the metering chamber; a vertical injection chamber; and a first conduit connecting the metering chamber to the injection chamber,
1. A vertical injection machine for injecting liquid metal comprising:a metering chamber; a liquid metal adjustment device comprising at least one recycle port located in the metering chamber; a vertical injection chamber; and a first conduit connecting the metering chamber to the injection chamber, wherein a height of liquid metal in the metering chamber determines a volume of metal in the injection chamber. 2. The vertical injection machine of claim 1, further comprising a solid metal feed source for feeding solid metal to the metering chamber.3. The vertical injection machine of claim 2, wherein the solid metal feed source includes a hopper, an ingot suspended by a wire, a conveyor belt or hand fed solid metal.4. The vertical injection machine of claim 1, further comprising at least one heater adjacent to the metering chamber.5. The vertical injection machine of claim 1, further comprising a slidable member having the at least one recycle port therein.6. The vertical injection machine of claim 1, further comprising a recycle conduit having one end fluidly connected to the at least one recycle port and the other end fluidly connected to a recycle container.7. The vertical injection machine of claim 1, further comprising a level sensor located in the metering chamber to determine the amount of metal in the metering chamber.8. The vertical injection machine of claim 1, further comprising an injection rod in the injection chamber, the injection rod adapted to cover a feed hole from the first conduit into the injection chamber when the injection rod is in an upper position and to uncover the feed hole when in a lower position, such that the height of liquid metal in the metering chamber determines a volume of metal in the injection chamber when the feed hole is uncovered.9. The vertical injection machine for injecting liquid metal comprising:a metering chamber; a vertical injection chamber; a first conduit connecting the metering chamber to the injection chamber; an injection rod in the injection chamber, the injection rod adapted to cover a feed hole from the first conduit into the injection chamber when the injection rod is in an upper position and to uncover the feed hole when in a lower position, such that a height of liquid metal in the metering chamber determines a volume of metal in the injection chamber when the feed hole is uncovered; and a base adapted to lift the injection chamber and the metering chamber toward a stationary mold. 10. The vertical injection machine of claim 9, further comprising an injection nozzle in a top portion of the injection chamber.11. The vertical injection machine of claim 1, further comprising a melt feeder and a second conduit, the second conduit connecting the melt feeder to the metering chamber.12. The vertical injection machine of claim 11, further comprising at least one heater adjacent to the melt feeder.13. The vertical injection machine of claim 11, wherein the melt feeder is located at a level below the metering chamber.14. The vertical injection machine of claim 11, further comprising a pump attached to the second conduit and adapted to pump liquid metal from the melt feeder to the metering chamber.15. A vertical injection machine for injecting liquid metal comprising:a vertical injection chamber; a metering means for determining a volume of liquid metal in the injection chamber by a height of the liquid metal in the metering means; a lifting means for lifting the injection chamber and the metering means toward a stationary mold; and a connecting means for providing the liquid metal from the metering means to the injection chamber. 16. The vertical injection machine of claim 15, further comprising an injection means for injecting liquid metal from the injection chamber into a mold.17. The vertical injection machine of claim 15, wherein the injection means is a means for covering a feed hole from the connecting means into the injection chamber when the injection means is in an upper position and for uncovering the feed hole when in a lower position, such that the height of liquid metal in the metering means determines a volume of metal in the injection chamber when the feed hole is uncovered.18. The vertical injection machine of claim 17, wherein the metering means is laterally spaced apart from the injection chamber such that a metal fill level in the metering means is at the same height as a metal fill level in the injection chamber when the injection means in the injection chamber is located below the feed hole.19. The vertical injection machine of claim 15, further comprising an injection nozzle in a top portion of the injection chamber.20. The vertical injection machine of claim 15, further comprising a means for providing metal into the metering means.21. The vertical injection machine of claim 15, wherein the connecting means is a means for allowing the liquid metal to flow from the metering means to the injection chamber by gravity alone.22. The vertical injection machine of claim 1, wherein the metering chamber is laterally spaced apart from the injection chamber such that a metal fill level in the metering chamber is at the same height as a metal fill level in the injection chamber when an injection rod in the injection chamber is located below a feed hole from the first conduit into the injection chamber.23. The vertical injection machine of claim 1, further comprising a base adapted to lift the injection chamber and the metering chamber toward a stationary mold.24. The vertical injection machine of claim 9, further comprising a solid metal feed source for feeding solid metal to the metering chamber.25. The vertical injection machine of claim 9, further comprising a melt feeder and a second conduit, the second conduit connecting the melt feeder to the metering chamber.
