Abstract
Certain exemplary embodiments can provide a system, machine, device, manufacture, and/or composition of matter configured for and/or resulting from, and/or a method for, activities that can comprise and/or relate to, investment casting a product in a mold, the product comprising at least one wall, the mold comprising a core, an inner primary shell, and an outer secondary shell.
Claims20
A method comprising:
- investment casting an airfoil in a mold, the airfoil comprising at least one wall, the mold comprising a core, an inner primary shell, and an outer secondary shell, the core seamlessly combined with the inner primary shell and integral with the inner primary shell yet substantially separated from the inner primary shell by one or more core gaps, the inner primary shell substantially separated from the outer secondary shell by one or more shell gaps, the one or more core gaps configured to receive molten metal at substantially the same time as the one or more shell gaps, the inner primary shell defining an exterior of the airfoil, the inner primary shell constructed of the same material as the core.
A method comprising:
- investment casting a product in a mold, the product comprising at least one wall, the mold comprising a core, an inner primary shell, and an outer secondary shell, the core integral with the inner primary shell yet substantially separated from the inner primary shell by one or more core gaps, the inner primary shell substantially separated from the outer secondary shell by one or more shell gaps, the one or more core gaps configured to receive molten metal at substantially the same time as the one or more shell gaps, the inner primary shell defining an exterior of the product, the inner primary shell constructed of the same material as the core.
An airfoil investment casting mold comprising:
- a core;
- an inner primary shell;
- and
- an outer secondary shell;
- wherein:
- the core is seamlessly combined with the inner primary shell and integral with the inner primary shell yet substantially separated from the inner primary shell by one or more core gaps;
- the inner primary shell substantially separated from the outer secondary shell by one or more shell gaps;
- the inner primary shell defines an exterior of an investment cast airfoil;
- the inner primary shell is constructed of the same material as the core;
- and
- the one or more core gaps are configured to receive molten metal at substantially the same time as the one or more shell gaps.
