Patent ID: 8029713

Claim:
A method, comprising: simultaneously injecting first and second resins into first and second cavities disposed in a first mold, through first and second nozzles, respectively, while the first mold and a second mold are closed, wherein the first and second nozzles supply the first and second molten resins independently to each of the first and second cavities and wherein a core passage is disposed downstream the first and second cavities to receive the first and second resins flowing therein; moving a core member within the core passage to block a fluid communication between the downstream portions of the first and second cavities, before injecting the first and second resins is completed; injecting a third resin through a third nozzle formed in the core member while moving the core member to provide the fluid communication of resins between downstream portions of the first and second cavities after injecting the first and second resins is completed to mix the first, second and third molten resin in the core passage; and separating the first and second molds after a cooling time, thereby yielding a single molded product.
