Abstract
A method for cooling molded preforms includes transferring preforms of a first injection cycle from a mold to retained engagement on a take-out plate, the preforms having exterior surfaces and interior surfaces targeted for cooling. The preforms are released from cooling tubes of the take-out plate to retained engagement on cooling pins of a transfer shell spaced away from the mold. The transfer shell rotates and the preforms are released from the transfer shell to retained engagement in supplemental tubes of a supplemental cooling device. After a period of time the preforms are released from the supplemental cooling device and transferred back to retained engagement on the transfer shell. The transfer shell rotates to an unload position to eject the preforms from the transfer shell for evacuation from the machine.
