Abstract
A simplified perform handling device including an end-effector arranged to substantially conform, in use, to an end portion of a preform and to seal therewith. The device also includes an aligning jig to align the preform with the end-effector. The device provides improved preform thermal and angular orientation characteristics when used in a transfer apparatus of an injection blow molding system, or simplified end-of-arm tool for two-stage preform production. The device may also be operated to condition a preform retained on the injection mold core plate assembly of an injection mold.
