ABSTRACT:
A mold, adapted for resin transfer molding of composite articles, that has a seal for maintaining a vacuum resulting in denser composite parts. A mold body has at least two openings including an opening for removing the article therethrough. There are at least two mold closures adapted for closing the openings and two of the mold closures are in mutual contact within the interior of the mold. A seal is disposed between each closure and the mold body for sealing each mold closure to the mold body to continuously seal only a single surface. The mold has an improved seal for initiating and maintaining a vacuum thus reducing part porosity.
