Abstract
An assembly for use in releasing a preform from a tooling fixture comprises a solid body engageable with the fixture via a seal, a manifold formed in the solid body and in flow communication with the preform via a plurality of holes in the tooling fixture, and a fluid source in flow communication with the manifold and configured to supply fluid to the manifold. The fluid comprises at least one of a gas and a slurry.

A method of releasing a preform from a tooling fixture, the method comprising:
- engaging a manifold assembly with the tooling fixture, the manifold assembly comprising:
- a solid body with a manifold formed therein;
- and a seal;
- securing the preform with at least one clamp;
- aligning the manifold with at least a subset of holes of a plurality of holes in the tooling fixture;
- and supplying a flow of fluid to the manifold such that the fluid traverses the subset of holes to exert a force on the preform;
- wherein prior to supplying the flow of fluid to the manifold, positioning a comb against the tooling fixture such that teeth of the comb align with holes of the tooling fixture.
