A film molding method and apparatus capable of shortening a mold cycle time and obtaining a molded product of an excellent quality. A method of hot-press molding a polyparaphenyleneterephthalamide (PPTA) film into a predetermined shape includes a first step of evaporating water from a PPTA film containing water at least 50% or more as a swelling agent, and obtaining an amorphous film having a density less than a predetermined density and a modulus in tension of about 70%; and a second process of hot-press molding the film for a predetermined time period by metal molds heated up to at least 330.degree. C. to crystallize the film to have a predetermined density specific to a PPTA film and produce an intrinsic physical value, and obtaining a molded product of the film. A film molding apparatus for performing the film molding method includes holes or slits opening at the surface of each of the metal molds, and an air suction unit and an air exhaust unit provided for each of the metal molds.
