Abstract
A compression mold includes punch and cavity components fabricated from initially flat sheets of relatively thin metal. The sheets of each component are shaped, assembled and joined to provide box-like components defining mating mold surfaces yielding molded parts which may be straight or laterally and/or vertically curved. The hollow interior of the two components allows for the circulation therethrough of an appropriate heat transfer medium to permit molding of either thermosetting or thermoplastic compounds.
