Abstract: A ladle for a molten metal includes a main body having a hollow interior and an opening for receiving the molten metal. The main body has a sidewall with a nozzle formed therein. The nozzle defines an axis of rotation for the main body. The nozzle contacts, seals and is in fluid communication with the mold. The nozzle is configured to deliver the molten metal to a mold when the main body is rotated from a first position to a second position.

Abstract: A composite thermal barrier coating (TBC) may be applied to a surface of components within an internal combustion engine. The composite TBC provides low thermal conductivity and low heat capacity insulation that is sealed against combustion gasses. The composite TBC includes three layers, bonded to one another, i.e., a first (bonding) layer, a second (insulating) layer, and a third (sealing) layer. The insulating layer is disposed between the bonding layer and the sealing layer. The bonding layer is bonded to the component and to the insulating layer. The insulating layer includes hollow microspheres that are sintered together to form insulation that provides a low effective thermal conductivity and low effective heat capacity. The sealing layer is a thin film that is configured to resist the high temperatures, present within the engine. The sealing layer is impermeable to gasses and presents a smooth surface.

Abstract: A method of transferring molten metal to a die casting mold is disclosed. The method includes providing a ladle with a dip well and a dispensing nozzle having a fluid metal filter formed therein as well as providing a receptacle fluidly between the ladle and the mold. Further the method includes delivering the molten metal from the ladle to the receptacle by positioning an exit face of the dispensing nozzle over the receptacle and rotating the ladle such that the exit face of the dispensing nozzle is repositioned proximal the bottom of the receptacle and conveying the molten metal that has been delivered to the receptacle into a mold cavity that is placed in fluid communication therewith.

Abstract: A device and method for transferring filtered molten metal to a die casting mold. The device and method include a casting filtration system that includes a funnel and a continuously replaceable filter placed fluidly between a molten metal source and a casting mold. Both the funnel and filter are automatically moved into cooperation with a molten metal receptacle such as a shot sleeve prior to each casting operation, and then automatically moved out of the way so that pressurization of the filtered molten metal may take place in the receptacle. In addition, the filter may be formed on a continuous strand such that indexed movement of the strand will advance the used portion of the filter out of the way to make room for a new unused filter portion that will be ready for a subsequent repeated casting operation.
