The present invention relates to a door trim and a molding apparatus and molding method thereof. According to the present invention, the molding apparatus comprises: a molding in which a first resin and a second resin are adhered to both sides, respectively; a first mold having a groove into which a part of the molding is inserted; and a second mold forming a closed mold with the first mold to come in contact with the molding and forming a first resin cavity and a second resin cavity on both sides with the molding as a boundary. The molding includes a body in which the first resin cavity and the second resin cavity are disposed on both sides and a protruding part protruding from the body toward the second mold, and the second mold includes a protrusion part protruding toward the first mold, wherein the protrusion part comes in contact with the body which is faced while surrounding both sides of the protruding part. Accordingly, different types of resins are simultaneously injected into both sides of the molding inserted into the mold as a boundary, and thus the molding and the different types of resins are molded in an integrated product.
