PURPOSE:To eliminate parting line mark and obtain a hollow fill formed item by a method wherein a manufacturing machine consists of a filling device to fill an elastic filling mold with filling material, a solidifying device and a withdrawing device and a sucking nozzle, which sucks non-solid filling material out of the interior of the elastic filling mold, is provided at the semisolidified position of the filling material in the solidifying device. CONSTITUTION:A manufacturing machine consists of a filling device 40 to fill the interior of an elastic filling mold 10 with filling material 11, a solidifying device 60 to solidify the filling material 11 and a withdrawing device 70. The elastic filling mold 10 consists of an open bag-like filling part 13 and a fixed part 14. In addition, a sucking nozzle 44 is positioned in the interior of the filling part 13 under the condition that only the periphery of the filling part 13 is in the solidified state so as to suck out the filling material at the central portion of the filling part 13 in order to further solidify the filling material 11, which is left behind onto the inner surface of the filling part 13 for obtaining a hollow fill formed item 12. The solidifying device 60 solidifies the filling material 11 by cooling or heating, depending upon the quality of the filling material 11. The withdrawing device 70 can push out the fill formed item 12 by pushing the item from the side, which is opposite to the opening part, of the elastic filling mold 10 by utilizing the elastic enlargement of the elastic filling mold 10. |
