<p>An injection molding technique is disclosed in which non-rigid or flexible components intended to be encapsulated within an interior of an injection molded product are held in postion in an interior of a mold cavity (11) during the injection operation by thin, rigid forks or blades (23, 24, 25) with surfaces interior to mold cavity contoured to mate with and capture the non-rigid, flexible component (17, 19). Such forks or blades can be retracted prior to the final packing portion of the molding cycle to allow plastic flow into the void left by the retracted blades, or the blades can be retracted after the end of the injection cycles and voids left in the molded product. Portions of the encapsulated components themselves can be fashioned to capture and hold portions of other encapsulated components during the injection process.</p> |
