Abstract
There is disclosed apparatus for rotationally casting a plastic liner for a pressure vessel having a metal access fitting molded therein. The apparatus includes a rotational casting arm having a mold supporting surface and adapted to be rotated about orthogonal axes. A hollow mold having a mold cavity surface conforming to the outside surface of the liner to be molded is removably attached to the mold supporting surface together with a metal access fitting. The metal access fitting has a longitudinal axis aligned with one of the orthogonal axes and has at least a first surface portion extending into the mold cavity. The first surface portion and the surface of the mold cavity are coated with plastic upon mold rotation to form the plastic liner.
