发明名称 Method for back-to-back blow molding of hollow bodies
摘要 First and second hollow bodies are blow molded in back-to-back alignment in a blow molding clamp having a central platen with first and second opposed, outwardly facing, mold supporting surfaces; a first movable platen with a mold supporting surface facing the first mold supporting surface of the central platen; and a second movable platen with a mold supporting surface facing the second mold supporting surface of the central platen; by continually extruding first and second parisons; positioning the first parison between the central platen and the first movable platen and the second parison between the central platen and the second movable platen; moving the movable platens to their closed position around the parisons; and simultaneously injecting a gas into the interior of the first and second parisons between each central platen and opposed first and second movable platens while the platens are in the closed position.
