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:
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 molding process utilizes a seed with a columnar grain structure for defining a desired grain structure in a completed casting. The seed is received within a seed cavity of a mold. The molten material adopts the orientation of the columns defined within the seed during solidification to form a completed molded article having a desired columnar grain structure.

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 die casting system includes a die, a shot tube, a shot tube plunger and a melting unit. The die includes a plurality of die components that define a die cavity. The shot tube is in fluid communication with the die cavity. A shot tube plunger is moveable within the shot tube to communicate a charge of material into the die cavity. The melting unit is positioned relative to the die and includes a bottom portion having an opening for selectively releasing a charge of material through the bottom portion.
摘要:
In an investment casting process, a composite core is formed as a combination of ceramic casting core element and a non-ceramic casting core element. The core is heated in an oxidative atmosphere and then heated in a non-oxidative atmosphere.

Systems and methods for reducing the potential for riser backfilling during investment casting are provided. In this regard, a representative method for performing investment casting includes: providing a mold having an opening communicating with an interior, the interior having a part cavity and a riser; providing an insert; and using the insert to form a physical barrier to reduce a potential for molten metal to backfill into the riser while the molten metal is introduced into the interior of the mold via the opening.
