Abstract
An injection molding apparatus, in which non-rigid or flexible components intended to be encapsulated within the interior of an injection molded product, is provided. The flexible components are held in position in the interior of the mold cavity during the injection operation by thin, rigid forks or blades with surfaces interior to the mold cavity contoured to mate with and capture the non-rigid, flexible component. 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.
