Abstract
A method and apparatus for the casting of metal components is disclosed. The apparatus includes a gooseneck for drawing molten metal from a crucible of hot metal and for forcing the drawn molten metal through the system, a hot runner assembly having a hot runner tip positioned adjacent the mold cavity, and a machine nozzle inserted between the gooseneck and the hot runner assembly. The gooseneck is fitted with a one-way check valve to allow for molten metal to be drawn into the plunger but to stop its passage out of the gooseneck when the metal is forced through the system into the die. A thermal valve is formed within the hot runner tip to provide a metal blockage from the molten metal which prevents the back-flow of molten metal back into the hot runner assembly. Both temperature and flow rate are carefully monitored and controlled.
