Abstract: A method for forming a molded grommet using a device which includes a fixed mold and a movable mold, the latter having three positions. The first is a closed position, wherein the two molds are adjacent each other with a middle plate between them. Second, there is an intermediate position in which the middle plate and movable mold are spaced apart from the fixed mold. Third, there is an open position, wherein the movable mold is spaced further from the fixed mold than the middle plate. A core is fixed to the movable mold and, when in the closed position; the two molds, the core, and the edge of the middle plate define the molding space into which moldable resin is introduced, thereby forming the grommet with the edge within the channel. As the core moves from the intermediate position to the open position, the middle plate is retained in the intermediate position; therefore, the core is pulled out of the grommet through the axial hollow therein.
