ABSTRACT:
Thermosetting molds are formed with electrically conductive surfaces for use in high frequency energy flow molding of sheet materials. Preferably the mold of this invention has a highly electrically conductive layer preferably in an epoxy gel coat carrying electrically conductive particles of gold, silver or platinum and positioned over a compatible epoxy mold body. A vacuum molding technique is used to obtain good surface definition in surface molding.
