    摘要: Le procédé consiste à soumettre à une agitation forcée les gaz injectés durant le cycle de moulage (gaz de soufflage, de réfrigération et/ou de traitement).
    Le dispositif fait appel à une tuyère de soufflage 1 équipée d'un ventilateur 5 à son extrémité.
    Le procédé et le dispositif permettent notamment la production de réservoirs à carburant en polyétylène présentant une imperméabilité améliorée.

    摘要: There is disclosed apparatus for rotationally casting a plastic liner (80) for a pressure vessel having a metal access fitting (54) molded therein. The apparatus includes a rotational casting arm (l0) having a mold supporting surface (38, 42) and adapted to be rotated about orthogonal axes (X, Y). A hollow mold (46) having a mold cavity surface (73) conforming to the outside surface of the liner to be molded is removably attached to the mold supporting suface 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 (58) 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.

    摘要: A method of molding a large returnable container (40) includes a heat treatment step that includes subjecting a thick preform (10) formed of a polyester resin, or a primary blow-molded article (20) obtained by subjecting the preform to primary blow molding, to intermediate blow molding with heating to obtain an intermediate molded article (30) from which a strain that has occurred during blow molding has been removed, and a final blow molding step that includes subjecting the intermediate molded article that has shrunk to final blow molding with heating to obtain a large returnable container. The heat treatment step includes disposing the preform or the primary blow-molded article in a heat treatment mold (204), and pressurizing the preform or the primary blow-molded article by introducing high-pressure air into the preform or the primary blow-molded article so that a shoulder (22) and a body (24) obtained by blow molding close contact to a cavity surface (204A) of the heat treatment mold, and are subjected to a heat treatment, the shoulder (22) being heated at a low temperature as compared with the body (24).
