There is provided a melting device including a melting cylinder that is heated to a predetermined temperature, melts a molding material supplied from a material supply port, and generates a molten material; an inert gas supply device configured to supply an inert gas onto a melting surface of the molten material and form an inert gas layer; and a low specific gravity gas supply device configured to supply a low specific gravity gas which is a gas having a different type from the inert gas and form a low specific gravity gas layer on the inert gas layer, wherein the low specific gravity gas layer has a lower specific gravity than the inert gas layer.

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 method for die casting a hybrid component includes defining a cavity within a die element of a die and inserting a spar into the cavity. Molten metal is injected into the die element. The molten metal is solidified within the cavity to cast the hybrid component. The spar establishes an internal structure of the hybrid component. The spar includes a high melting temperature material that defines a first melting temperature greater than a second melting temperature of the molten metal.
