Abstract:
1. A vented metal casting system comprising: a first die defining a first interior casting surface adapted to receive and contact molten metal; a second die defining a second interior casting surface adapted to receive and contact molten material, the second die positionable with the first die between open and closed states such that upon positioning the second die in a closed state, the first interior casting surface and the second interior casting surface define an interior casting chamber; wherein at least one of the first die and the second die define a vent passageway extending from a region located along an upper surface of the casting chamber; a heating element in thermal communication with the vent passageway, the heating element positioned in the vent passageway to prevent or at least substantially prevent material deposition from gases flowing through the vent passageway from the casting chamber during a casting operation, the heating element positioned spaced apart from an internal vent surface defining the vent passageway to reduce heating of the die.
