ABSTRACT:
For the production of hollow articles from thermoplastics, such as wide-necked vessels, bottles and the like, an amorphous parison is injection-molded, warmed to a temperature above the glass transition temperature of the plastic, placed in a mold and stretch blow molded to give a hollow article. During the stretch blow molding, a liquid coolant, preferably water, is metered into the mold in such an amount that the temperature of the parison remains approximately constant or increases only insignificantly.
