ABSTRACT:
This invention relates to the sealing of heated enclosures wherein the enclosure is provided with an opening (16) allowing access to the interior of the enclosure. A means for heating the enclosure and a means for closing (22) the access opening (16) are also provided. A compliant sealing material (26) disposed about the periphery of the access opening (16) is between the enclosure (10) and the closing means (22). A thermosetting material is intermixed with the sealing material (26) such that when the heating means heats the enclosure (10) the thermosetting material allows the sealing material (26) to be permanently molded to the shape of the closing means (18). A method of sealing a heatable enclosure (10) having an access opening (16) and a door (18) closing the enclosure (10) is also provided.
