ABSTRACT:
Post-mold cooling of injection molded plastic articles such as preforms is achieved by transferring the articles directly from the mold cavities onto cooling cores carried by a take-out plate. The molded articles are supported on the cooling cores until they become sufficiently frozen that they can be stripped from the cores.
