An apparatus produces a resin product which includes a first resin layer partially covered with a second resin layer so that a boundary line between the first and second resin layers is visible from the outside. The apparatus may include a first mold side having a recess, a second mold side configured and dimensioned to enclose the recess of the first mold side, a slide core movably fitted in the recess of the first mold side, which may be movable toward the second mold side to an extracted position to define a first cavity, and may be movable rearward to a retracted position after a first resin is injected into the first cavity to form the first resin layer, thus defining a second cavity into which a second resin is injected to form the second resin layer, the slide core including a dam dimensioned and configured to form a groove in the first resin layer during the formation of the first resin layer, wherein the dame partially positioned in the groove during the formation of the second resin layer, a first resin supply unit for supplying the first cavity with the first resin, and/or a second resin supply unit for supplying the second cavity with the second resin. The resin product produced by the apparatus is excellent in appearance, and obviates the post-processing formation of a tear line. Methods of forming the resin product are also described.
