ABSTRACT:
The framed printout is connected to an expendable core for a high-pressure die casting die, which printout is spaced outside and surrounds the cavity in the die. The casting and its cavity in the die has at least one open side into which the core is positioned, such as to form a jacket around a cavity in a casting. The die has in its parting surface a pocket for seating the frame of the printout and its connections to the core, which pocket is spaced from and is outside the casting cavity in the die.
