ABSTRACT:
An apparatus and method for molding thermosetting material into shaped articles rapidly and without the occurrence of hot spots or other defects. A mold having a cavity conforming to the shape of the article to be molded is provided and is filled with thermosetting material. An energy source generates electromagnetic energy in the microwave range and a coupling means is provided for causing the electric field component of the generated energy to uniformly irradiate the volume of thermosetting material in the mold cavity.
