ABSTRACT:
A method of expanding the shot tip in a die cast machine to maintain a sealing fit between the cold chamber and shot tip includes positioning a separate tool with an annular projecting beveled rim in the cold chamber and between the chamber and the movable die half and advancing the shot plunger to cause the beveled rim to project into and expand the periphery of the working end of the shot tip to provide a sealing fit. The expanding tool is used periodically in the casting cycle when required to maintain the desired fit of the shot tip with the cold chamber to prevent entry of metal in the space between the shot tip and the chamber which can cause galling and binding of the plunger in the chamber.
