A mold and a process for controlling the weight and wall thickness distribution in a blow molded plastic manufactured article or a family or related articles involves simultaneous formation of the manufactured article and a waste article. The waste article is removed and recycled to manufacture further articles. The waste article forming chamber increases the apparent depth of the manufactured article chamber to create a larger apparent surface area, so that the parison is being blown over a much larger surface area, creating a reduced actual part weight and actual wall thickness.
