A method for the manufacture of plastic containers. In a first embodiment of the invention a tubular length of thermoplastic material is severed from an extruder and blown into a preform shape in a movable preform mold. After completion of the cycle, the preform mold opens and returns to the extruder for a new section of material. The preform shape remains in the location where it was formed. Return of the preform mold moves the previously completed preform shape into registry with a conditioning mold. At this location, it is grasped by an indexable neck clamp. After completion of the thermal conditioning provided by the conditioning mold, the preform shape is indexed to a final shape mold where it is given its final configuration. The completed container is then indexed to a removal station for ejection from the forming process. In another embodiment of the invention, the preform shape is not retained at the preform mold station while a new length of material is obtained by the preform mold, but rather is indexed to the conditioning mold station during the time the preform mold is moving to and from the extruder to obtain a new length of material.
