摘要:
A method of manufacturing a casting article for use in a casting process includes rapidly forming the casting article out of a metallic material. A ceramic coating is applied to an exterior surface of the casting article.
摘要:
An induction heated furnace assembly for producing a directionally solidified casting includes a susceptor that tailors strength of the magnetic field within the chamber to provide a desired grain structure in a completed cast part. The susceptor proportionally blocks portions of the magnetic field to provide different levels of magnetic stirring within the molten material at different locations within the furnace assembly stirring induced by the magnetic field is controlled and varied throughout the furnace assembly to create the desired grain structures in the completed cast article.
摘要:
An example die casting system includes a die comprised of a plurality of die components that define a die cavity configured to receive a molten metal. One of the die components comprises a material that is not reactive with the molten metal and has a melting temperature above 815 degrees Celsius.
摘要:
A hybrid core assembly for a casting process includes a ceramic core portion, a first refractory metal core portion and a first plate positioned between the ceramic core portion and the first refractory metal core portion. The ceramic core portion includes a first trough. A portion of the refractory metal core portion is received in the first trough.
摘要:
A method of forming a cast component includes at least partially surrounding an investment mold in a heat-insulating packing material, feeding a molten alloy into the investment mold to provide a filled investment mold, and agitating the filled investment mold while solidifying the molten alloy.
摘要:
A die casting system includes a die, a shot tube, a melting system and a vacuum system. The die includes a plurality of die components that define a die cavity. The shot tube is in fluid communication with the die cavity and is operable to deliver a charge of material to the die cavity. The melting system is positioned adjacent to the die and includes an alloy loader, a melting unit and a crucible. The vacuum system defines a first chamber and a second chamber separated from the first chamber by an isolation valve. The melting system is disposed within the first chamber, and the die is disposed within the second chamber.
摘要:
A method for die casting a component includes inserting at least one sacrificial core into a die cavity of a die comprised of a plurality of die elements. Molten metal is injected into the die cavity. The molten metal is solidified within the die cavity to form the component. The plurality of die elements are disassembled from the component, and the at least one sacrificial core is destructively removed from the component.
摘要:
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.
