摘要:<p>In a blow molding process in which a parison is blown to form an article which is then cooled and recovered, a liquified gas is introduced into the interior of partially blown article where it becomes vaporized and causes the completion of the blowing step as well as to cool the article. A mixture of the blowing gas and vaporized liquified gas is recovered and recycled for use as the blowing gas in a subsequent blow molding step.</p>
