<p><P>PROBLEM TO BE SOLVED: To produce a hollow molding with partition boards which have excellent chemical resistance etc., and high denseness and suppress the occurrence of leakage etc., installed by a rotational molding method. <P>SOLUTION: In a method for producing the hollow molding 1 in which the partition boards 3 and 4 partitioning internal spaces A1, A2, and A3 are installed by the rotational molding method, after partition members 3 and 4 with resin layers 3b and 4b formed on at least the entire surfaces are set in a mold, and their positions are fixed, the mold is heated to heat/melt a powdered thermoplastic resin charged in the mold, and the mold is rotated to make the molten resin adhere to the inner wall surface of the mold to form the wall part 2 of the hollow molding. The resin layers on the surfaces of the partition members are integrated with the molten resin. The partition boards 3 and 4 comprising the partition members and the wall part 2 of the hollow molding are formed integrally to mold the hollow molding 1 with the partition boards 3 and 4 formed inside. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
