ABSTRACT:
A method of sealing an opening in a cast member that employs a green seal cap formed from the consolidation of a mixture of powdered metal and a binder under sufficient pressure to impart enough strength to the cap to maintain its shape during the blade manufacturing process. The green seal plate cap is inserted into the opening in the cast member and the cast member is subjected to iso-static pressing, which bonds the seal plate cap to the cast member and sinters the cap to form a solid seal.
