Abstract: A shot tube includes an inner bore for delivering molten material into a die-cast mold. The shot tube has an outer peripheral surface with at least one surface for receiving a locking member to lock the shot tube into an aperture in a fixed mold portion and an alignment structure for properly aligning the shot tube in the fixed mold portion. An opening receives molten material into the inner bore. A die-cast machine is also disclosed.

Abstract: A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled wherein each hot core plate is directly interlocked to the at least one cold core plate. A wax pattern is formed with the core assembly. An external shell is formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material and cures the molten material. The external shell is removed. The core assembly is removed. A core assembly for a cast heat exchanger is also disclosed.

Abstract: A die casting system includes a die including at least one die component that defines a die cavity, a spar received within a portion of said die cavity, a shot tube in fluid communication with the die cavity, and a shot tube plunger moveable within the shot tube to communicate a molten metal into the die cavity to cast a hybrid component. The spar establishes an internal structure of the hybrid component, and one of the internal structures and an outer structure of said hybrid component is an equiaxed structure.
