ABSTRACT:
An injection molded parison is slightly preblown from the core rod and cooling water is then circulated both externally and internally on the parison so as to effect a rapid temperature decrease in the parison. The internal circulating cooling water initially passes through the core rod and then into contact with the parison. After circulating the water, a drying fluid is then circulated into contact with the parison to remove residual water. The method and apparatus of this invention are useful in controlling the cooling of certain thermoplastic parisons in which rapid cooling is necessary to achieve the desired crystal growth for subsequent biaxial or multiaxial orientation.
