Abstract:
1. A method for creating a molded part, comprising the steps of: a) providing a mold system having a mold cavity therein, said mold system being configurable in a first and a second configuration; b) providing a retracting member having an end and being selectively movable between extended and retracted positions in said mold cavity; c) configuring said mold system in said first configuration with said retracting member in said extended position such that said end is spaced from a surface of the mold system; d) injecting a first mold material into the mold cavity to form a first portion of a molded part, the first portion of the molded part including a wall portion defined between the end of said retracting member and the surface of the mold system; e) configuring said mold system in said second configuration with said retracting member in said retracted position, said second configuration providing first and second cavity portions separated by said wall portion; and f) injecting a second mold material into the mold cavity to form a second portion of the molded part, the second mold material removing the wall portion and filling said first and second cavity portions and the space occupied by said wall portion with the second mold material, forming a connection between the first and second portions of the molded part.
