Abstract
Method and system for producing a part using die casting or injection molding with a top die and undercut dies that are independently moveable from the top die. In one particular form, the method and system can include a top die and one or more undercut dies that can have a protrusion. The undercut dies can be lowered into a base of the system and moved away from each other, and the top die can be lowered into a receiving portion between the undercut dies. A molten liquid can be introduced into a space between the undercut dies and additional aspects of the system, and after cooling to form a part, the top die can be moved vertically to allow space for the undercut dies to be moved toward each other. The undercut dies can be moved vertically and the part can be removed.
