Abstract

An injection molding system for injection molding a plurality of molten materials into a mold cavity includes a nozzle, a drop tip supported by the nozzle, and a central bore extending through the nozzle and drop tip. The injection molding system also includes a first and second flow passage each extending through the nozzle, so as to define a first and second nozzle flow passage, and drop tip, so as to define a first and second drop tip flow passage. The first and second drop tip flow passages each include a plurality of branching portions each defining a junction at which the respective flow passage communicates fluidly with the central bore.
