Title:
METHOD AND DEVICE FOR MANUFACTURING HOLLOW PRODUCT THROUGH BLOWING MOLDING
Document Type and Number:
Japanese Patent JPS591227
Kind Code:
A
Abstract:
The present invention provides an injection blow molding process and apparatus for use in the blow molding of containers in which a preform (1) is molded onto a core (20) and is subsequently moved relative to the core (20) to space a body portion (8) of the preform (1) from the core (20) to facilitate the temperature conditioning of the preform (1) to achieve a desired biorientation of the thermoplastic material from which the preform (1) is made when the preform (1) 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 (1) with or without the assistance of a supply of gas to the preform (1) at a desired temperature.
