ABSTRACT:
In the casting of metal alloys with low melting temperatures, there is provided a nozzle for an interface connection between a transfer line and a die which permits misalignment and a variable height differential. Meal alloys with low melting temperatures are made for cores in subsequently molded plastic components and for encapsulating components for machining the other finishing steps. The nozzle has a base with a valve therein, a nozzle body adapted to move relative to the base to open the valve, and a spring to hold the valve closed. A sleeve joins the nozzle body and the base, and a connector on the nozzle body provides an interface connection between the transfer line and the die so that when the connector interfaces with the die, the valve is open.
