a method of molding an object with a mold having a transfer face includes the steps of filling , separating , re - melting , re - contacting , cooling , and removing . the filling step fills a thermoplastic material , having a temperature greater than a softening temperature of the thermoplastic material , into a cavity space in the mold having a temperature smaller than the softening temperature of the thermoplastic material . the thermoplastic material comes in contact with the transfer face and is cooled . the separating step separates the transfer face from the thermoplastic material to form a heat - insulating layer between the thermoplastic material and transfer face . the re - melting step re - melts the thermoplastic material with heat energy retained inside the thermoplastic material . the re - contacting step re - contacts the re - melted thermoplastic material to the transfer face . the cooling step cools the thermoplastic material to a temperature smaller than the softening temperature of the thermoplastic material . the removing step removes the cooled thermoplastic material from the mold .
