A method of manufacturing a door skin includes the steps of providing a wood composite flat blank. The blank is placed between the platens of a heated press, the platens being heated to a temperature sufficient to soften the resins in the blank and to thereby soften the blank. Sufficient pressure is applied to close the platens and thereafter the pressure is cyclically applied to increased pressure levels for thereby causing the blank to be deformed into a molded shape determined by the configuration of the platens. The molded blank is then removed from between the platens.
