ABSTRACT:
This invention is directed to a novel method and apparatus for casting stress-free thermosetting resin materials. A process for forming a thermosetting product which comprises: (a) pouring a thermosetting polymer, with initiator, and catalyst, into a cavity of a mold which has a polymer coating or film on the interior surface thereof; (b) permitting the polymer to cure to a point where the cured material is reasonably dimensionally stable; (c) removing the partially cured polymeric material from the mold and placing the material in an oven; and (d) fully curing the polymeric material in the oven.
