Abstract: Fixtures including supports for holding various components are disclosed. The fixtures may include a first member including two opposing side rails positioned opposite and parallel to one another, and at least two supports extending between each of the two opposing side rails. The at least two supports may contact removable features formed on the component. The fixture may also include a second member contacting the first member. The second member may include two opposing side rails positioned opposite and parallel to one another. The two opposing side rails of the second member may be positioned on and may contact the two opposing side rails of the first member. The second member may also include at least one support extending between the two opposing side rails of the second member. The at least one support may contact removable features formed on the component.

Abstract: In one embodiment, a fixture for supporting a body in an oven includes a plurality of support ribs to support the body, and a support element to support and connect the plurality of support ribs. Each support rib has a length, a width, a thickness, and a first end. The length extends from the support element to the first end, and the width extends perpendicular to the length. The length varies across the width of at least one support rib. In another embodiment, a fixture for supporting a body in an oven includes a plurality of connected support ribs to support the body. Each support rib is spaced from at least one other support rib. The length differs for at least a first support rib of the plurality of support ribs with respect to at least a second support rib of the plurality of support ribs.

Abstract: A disposable core die is provided. The disposable core die includes a first portion defining an inlet configured to receive a slurry therethrough, a second portion integrally formed downstream from the first portion and configured to receive the slurry from the first portion, and a third portion integrally formed downstream from the second portion. The second portion includes a plurality of hollow tubes that are substantially coaxially aligned and have a wall thickness within a range defined between about 0.1 mm and about 0.5 mm, and the third portion defines an outlet configured to discharge excess slurry from the second portion.
