Abstract
In a blow molding process, a fused thermoplastic polymer parison is interposed between a pair of split molds. The split molds are closed around the parison to seal the ends. A small diameter hollow needle is inserted through one of the split molds and fluid is blown into the parison forming a balloon. After the balloon begins to form, a large diameter hollow needle is inserted while internal pressure is applied to the parison via the small diameter hollow needle, and a large amount of fluid is blown in. This process is highly productive and reduces the conventional blow molding cycle by 60 percent due to the rapid cooling of the hollow article.
