A method of molding an integral joint including a stationary member connected to a first part by spaced apart tabs (22, 24) and an enclosure extending out from a second part and rotatable about the stationary member between the spaced apart tabs (22, 24), said method comprising the steps of: providing a joint formation assembly that includes first and second central slides and first and second end slides, wherein the first central slide defines a first outer cavity half and the second central side defines a second outer cavity half, wherein each of the first and second central slides further defines an inner cavity portion (54, 56) that is divorced from the respective outer cavity half (42, 46) by a separating wall, wherein the first end slide defines an inner cavity portion that is continuous with the inner cavity portion of the second central slide, and wherein the first end slide further defines a first end cavity that is shaped to form a first tab, wherein the first end slide seals off the second outer cavity half, wherein the second end slide defines an inner cavity portion that is continuous with the inner cavity portion of the first central slide such that the inner cavity portions (54, 56, 70, 86) together form an inner cavity, wherein the second end slide further defines a second end cavity that is shaped to form a second tab, wherein the second end slide seals off the first outer cavity half to divorce the inner cavity and end cavities (72, 88) from the outer cavity; introducing moldable material into the inner cavity from a first passageway; filling the inner cavity with moldable material to form the stationary member; filling the end cavities (72, 88) with moldable material to form the tabs (22, 24) integral with the stationary member; introducing moldable material into the outer cavity from a second passageway; filling the outer cavity witch moldable material to form the enclosure; and forming the stationary member and the tabs, separately and independently forming the enclosure around the stationary member and between the tabs (22, 24) to allow rotatable movement of the enclosure relative to the stationary member. providing a joint formation assembly that includes first and second central slides and first and second end slides, wherein the first central slide defines a first outer cavity half and the second central side defines a second outer cavity half, wherein each of the first and second central slides further defines an inner cavity portion (54, 56) that is divorced from the respective outer cavity half (42, 46) by a separating wall, wherein the first end slide defines an inner cavity portion that is continuous with the inner cavity portion of the second central slide, and wherein the first end slide further defines a first end cavity that is shaped to form a first tab, wherein the first end slide seals off the second outer cavity half, wherein the second end slide defines an inner cavity portion that is continuous with the inner cavity portion of the first central slide such that the inner cavity portions (54, 56, 70, 86) together form an inner cavity, wherein the second end slide further defines a second end cavity that is shaped to form a second tab, wherein the second end slide seals off the first outer cavity half to divorce the inner cavity and end cavities (72, 88) from the outer cavity; introducing moldable material into the inner cavity from a first passageway; filling the inner cavity with moldable material to form the stationary member; filling the end cavities (72, 88) with moldable material to form the tabs (22, 24) integral with the stationary member; introducing moldable material into the outer cavity from a second passageway; filling the outer cavity witch moldable material to form the enclosure; and forming the stationary member and the tabs, separately and independently forming the enclosure around the stationary member and between the tabs (22, 24) to allow rotatable movement of the enclosure relative to the stationary member.
