Abstract
In a blow molding process the mold halves are independently controlled and moved so that a parison may be extruded from an extrusion head and then one of two mold halves may be moved toward the parison. The parison may be grasped by a manipulator to manipulate a portion of the parison so as to overlie a second portion of the mold cavity. The mold is then closed and a standard blow molding procedure performed. The process enables production of reduced flash.
