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