ABSTRACT:
A plurality of core rods with parisons thereon are mounted to an indexing head with the core rods disposed in a temperature conditioning chamber and wherein the core rods are simultaneously rotated to effect temperature distribution throughout the parisons. Pluralities of core rods are angularly disposed and simultaneously rotated. The apparatus is particularly useful in orientation injection blow molding, wherein the parison is a relatively thick cross section or wherein the parison thermoplastic has a low thermal conductivity.
