ABSTRACT:
A process is described which uses overmolding to create an all plastic waterway within a faucet leading up to an inlet port for a spout. The waterway connector has at least two arms and a central connector and wherein the process includes the steps of: at least partially inserting one end of a tube into a first split mold; inserting at least two pins at least partially into the mold, a first pin inserted into the at least one end of the tube and a second pin inserted essentially normal to the direction of insertion of the first pin; injection overmolding a first geometry onto the one end of said tube and forming a profile for fluid transfer with the second pin and associated mold surfaces, the profile having a terminal lip; at least partially inserting two of the profiles with terminal lips into a second split mold, each of the profiles being a mirror image of the other, onto a core having a mating profile for each lip, the mating profile on said core comprising opposing grooves; and injection overmolding a second geometry about the lips to form a leak-proof upwardly extending connector. The process optionally contains the step of crosslinking the waterway connector.
