Abstract
A method of producing a substantially finished surface on the outmold side of a thermosetting casting. The method entails preparing a first laminae having a curable thermosetting resin material as a first outmold surface, and providing a second laminae having an imprinted surface thereon. The first surface and second laminae having an imprinted surface are then positioned in face-to-face registration with one another. Substantial vacuum conditions are generated in the area between the first surface and the imprint surface, and the surfaces are pressed together under substantial vacuum conditions. The vacuum and pressure conditions maintain the surfaces in face-to-face registration and contain any volatile components of the curable thermosetting resin material of the first laminae while the curable thermosetting resin material cures. After the curable thermosetting resin material cures, the second laminae having an imprinted surface is separated from the first laminae to form the substrate having the imprint of the second laminae.
