Abstract
The present invention provides a multiple platen-multiple position press or injection blow molding apparatus for use in the blow molding of containers in which a preform is molded onto a core and is moved relative to the core to space a body portion of the preform from the core when the core is in the blowing station to facilitate the temperature conditioning of the preform to achieve a desired biorientation of the thermoplastic material from which the preform is made when the preform is blow molded to form a container. The temperature conditioning may be achieved by allowing stabilization of the temperature gradient through the material of the preform with or without the assistance of a supply of gas to the preform at a desired temperature.
