PURPOSE:To mold an excellent molded object quickly, while the deviation of the thickness of a parison is removed especially when the parison is deformed by the deformable assembled object composed of a plurality of piece members in the flow molding method and its device. CONSTITUTION:In blow molding method and its device, the deformable assembled object A in which a plurality of piece members 2, 4, 6 aranged in series in a heat resistant tube 60 are mutually connected by a plurality of wires 8a, 8b, and the connected state of each piece member 2, 4, 6 is made deformable by way of the wires 8a, 8b, is positioned in a parson 20 with a heat resistant tube 60. Then the parison 20 is preformed into a prescribed shape by bending the shape of the deformable assembled object A by way of the heat resistant tube 60. After the closing of a mold 26, pressurized fluid is fed into the parison 28, and a molded object B is obtained, and then the deformable assembled object is removed from the molded object B by loosening the wires 8a, 8b. |
