The methods of manufacturing molds from shape memory materials and molds made
thereby, in accordance with the present invention, provide numerous advantages
for molding castable composite parts. The initial mold cost is low enough to accommodate
economical production of as few as a single part incorporating high surface definition
and intricate three dimensional detail. The preferred methods and molds made thereby
are transparent, thereby, curing of the corresponding part by ultra-violet and
infra-red light is made possible, as well as, visual inspection during injection
and curing of the given resin. Removal of the cured part from within the mold is simplified.
