Abstract
A method for blow molding first and second articles, each having a different shape, includes the step of changing the positioning between an extruder head and a mold set after forming the first article from a first parison. The mold set has first and second mold halves which define first and second cavities having different shapes. The step of changing the positioning between an extruder head and a mold set may include changing the position of the mold set or changing the position of the extruder head.
