Abstract: The present invention pertains to an overmolding process and apparatus for overmolding nonlinear profiles from rigid or semi-rigid polymeric material. Rigid polymeric materials are melted and overmolded onto an extruded profile, which is received by a mold having a mold cavity and core pin. The mold cavity and core pin have a radial angle of curvature (Rc). In the overmolding process, rigid polymeric material is injected around the core pin and cavity, and the overmolded article is removed from the mold. The core pin is removed from the overmolded article to form a non-linear overmolded article according to the present process and arrangement of parts.

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.

Abstract: An air tunnel diverter for a refrigeration unit includes one or more leg members secured to a hub. The hub is generally formed to include a fitting through which cooler air is passed to the leg member and routed into the desired locations within the refrigerated space. The leg member is placed on the fitting by sliding one end of the leg member onto a leg portion of the fitting. The fitting is then secured to the leg member by an overmolding process in which a soft flexible plastic is cast or otherwise applied around the connection. Installation is further simplified by providing the leg member with a flexible portion. The air tunnel diverter is preferably secured in the refrigeration unit by foam insulation.
