A bushing including a body portion including a cylinder portion having a bore there through configured to receive a bolt; a flange portion orthogonal and integral to the cylinder portion, the flange portion configured to abut a load bearing surface of a flange; a lip portion orthogonal to and integral to the flange portion proximate the cylinder portion, wherein the lip portion redistributes a flange load.

Fan case bushing

An example molten material funnel includes a first outlet lip and a second outlet lip. The first and second outlet lips are configured to both contact molten material communicated through the molten material funnel.

A case for a gas turbine engine incudes a radial flange with a partial scallop along an inner diameter of the radial flange. A case assembly for a gas turbine engine incudes a first case with a first radial flange with a partial scallop along an inner diameter of the first radial flange, the partial scallop adjacent to a first aperture through the first radial flange and a second case with a second radial flange with a second aperture through the second radial flange, the second radial flange mountable to the first radial flange at an interface such that the second aperture is axially aligned with the first aperture and a seal lip that extends from the second case interfaces with said first case at a longitudinal interface.

A die casting assembly has a cavity defined by multiple dies, the cavity includes at least one sharp corner. Each of the dies includes multiple die segments. A die segment joint between at least two of the die segments is aligned with the sharp corner.

Segmented die casting block

An example component polishing method includes polishing a component protecting portions of the component during the polishing using a barrier spaced from the component. The barrier is configured to move together with the component during the polishing.
