Abstract
A method of manufacturing a coupling segment including: obtaining a mold having an interior and an exterior, the interior defining an interior surface, the interior surface defining a cavity, the cavity including a border line at an outermost edge of the cavity; placing a material in liquid form into the cavity in the mold; and removing a coupling segment from the mold, the coupling segment formed from the material, the coupling segment including an outer surface, an inner surface, a first end, a second end, and a parting line extending along the border line of the cavity of the mold prior to removal of the coupling segment from the mold, the parting line offset from a top surface of each end.
Claims18
A method of manufacturing a coupling segment comprising:
- obtaining a mold having an interior and an exterior, the interior defining an interior surface, the interior surface defining a cavity, the cavity including a border line at an outermost edge of the cavity;
- placing a material in liquid form into the cavity in the mold;
- solidifying the material in the cavity in the mold;
- and
- removing a coupling segment from the mold, the coupling segment formed from the material, the coupling segment including
- an outer surface,
- an inner surface,
- a first end,
- a second end,
- a first fastener pad protruding proximate to the first end, wherein the first fastener pad comprises a first fastener pad top surface defining a first fastener pad top surface plane,
- a second fastener pad protruding proximate to the second end, and
- a parting line extending along the border line of the cavity of the mold prior to removal of the coupling segment from the mold, the parting line offset from the first fastener pad top surface,
- wherein a portion of the parting line extending around the first fastener pad defines a first fastener pad parting line plane,
- and wherein the first fastener pad top surface plane is angled with respect to the first fastener pad parting line plane.

- an upper body surface of the coupling segment adjacent to the parting line sloping inwardly from the parting line towards a vertical axis of the segment, and
- a lower body surface of the coupling segment adjacent to the parting line sloping inwardly from the parting line towards a vertical axis of the segment.
