  • Component protection from contaminants
    Patent number: 5283020
    Abstract: During the manufacturing process for turbine blades and vanes, among other hollow articles, the hollow cavities can become contaminated. Removal of the contaminants is a tedious, time consuming process which commonly results in component rework or rejection. Introducing a foam filler into the hollow cavities, prior to manufacturing, prevents contamination; enhancing manufacturing efficiency and component integrity.
