Abstract:
1. Method, comprising: manufacturing an internal core for an injection mold tool wherein the profile of the internal core has a tapered wall portion and a parallel wall portion; determining a delineation line separating the tapered wall portion from the parallel wall portion for separating the internal core into a tapered wall component part and a parallel wall component part; separating the internal core into a tapered wall component part and a parallel wall component part; manufacturing the external surface of the tapered wall component part using a wire electric discharge machining manufacturing process to produce the desired shape and configuration; manufacturing the external surface of the parallel wall component part, simultaneously with the manufacturing of the tapered wall component, using a right angle manufacturing process to produce the desired shape and configuration; and joining the tapered wall component part and the parallel wall component part to form the internal core.
