Method for molding resin to skin members
 A resin part such as an instrument panel, a console box or door trim has a substrate body made of hard resin and a skin mounted on a surface of the substrate. To produce the resin part, a preformed elastic sheet is set within a mold cavity. Then, a molten resin is injected into the cavity through gates. The molten resin is first injected into the cavity through gates that are opposed to the skin and after the passage of a predetermined time, the resin is injected through gates that are not opposed to the skin, thereby forming a substrate that has the skin thermally fused to a surface thereof.
