Abstract
A novel ledge forming system used to attach a polymer retention hub to a thin wall nozzle core to provide an efficient way to produce a conjunct nozzle. The inventive apparatus provides a means for assembly of components by a method involving use of a press with a heating element to elevate temperature of a thermoplastic polymer to permit formation of a ledge that overhangs the flange of a nozzle core, mechanically locking components together. Execution of the process is rapid, low cost and eliminates damage to the thin wall of the core that would occur if the polymer retention hub were molded around the nozzle core.
