A method of optimizing a door trim injection molding process is disclosed. The purpose of an embodiment of the present invention is to provide a method of optimizing the door trim injection molding process, which optimizes mold and process conditions when manufacturing a door trim by injection molding. The method according to an embodiment of the present invention comprises: a door trim equivalent model defining step of calculating equivalent thickness and shape factor of a speaker grill by using an equivalent model of the door trim, calculating reference shape information corresponding to a shape of the speaker grill by using the calculated equivalent thickness and a shape factor, and reflecting the calculated reference shape information to define door trim information; a door trim mold designing step of designing a mold by using the door trim information defined in the door trim equivalent model defining step; and a door trim injection process condition optimizing step of optimizing injection process conditions of the door trim designed in the door trim mold designing step, wherein the door trim injection process condition optimizing step obtains a design value of the injection process conditions at which deterioration index according to position of a weld line of the designed door trim and sharpness of the weld line are minimized.
