ABSTRACT:
A vertical injection machine having a first chamber for supplying liquid metal, a second chamber located lower than the first chamber and a first conduit connecting the first chamber to the second chamber. The first conduit has a shutter rod disposed within and a valve head attached to a lower portion of the shutter rod. The valve head is adapted to seal a lower portion of the first conduit. A metering rod is disposed within the second chamber. The vertical injection machine also includes a vertically oriented third chamber and a second conduit connecting the second chamber to the third chamber. An injection rod is disposed vertically within the third chamber and a injection nozzle is located at an upper portion of the third chamber.
