PROBLEM TO BE SOLVED: To manufacture a table coral duplication that considerably resembles real table coral.SOLUTION: For an original mold of a table coral, a reverse side mold R and a front side mold F are structured through gypsums 3, 5 using a mixed solution of a reverse side silicone resin 2 and a mixed solution of a front side silicone resin 4. From the original mold of the table coral, the reverse side silicone resin 2 and the front side silicone resin 4 are peeled off respectively, the mixed solution of a front soft urethane 6A and a mixed solution of a reverse soft urethane 6B are poured into the reverse side silicone resin 2 and the front side silicone resin 4 of the reverse side mold R and the front side mold F, respectively. Subsequently, at least the front side silicone resin 4 of the front side mold F and the mixed solution of the front soft urethane 6A are placed in a vacuum device 8, with defoaming operation performed. Then, with the reverse side mold R and the front side mold F oppositely faced, the mixed solution of an internal soft urethane 6C is poured in the opposing space to manufacture a table coral duplication 99.COPYRIGHT: (C)2016,JPO&INPIT【課題】本物のテーブルサンゴにかなり近似したテーブルサンゴ複製物を製造する。【解決手段】テーブルサンゴ原型に対して、裏面側シリコン樹脂2の混合液及び表面側シリコン樹脂4の混合液を石膏3,5を介して裏面側型R及び表面側型Fを構成する。テーブルサンゴ原型から裏面側シリコン樹脂2及び表面側シリコン樹脂4をそれぞれ剥がして、裏面側型R及び表面側型Fの裏面側シリコン樹脂2及び表面側シリコン樹脂4に対して、表面軟質ウレタン6A及び裏面軟質ウレタン6Bの混合液を流し込む。その後に、少なくとも表面側型Fの表面側シリコン樹脂4及び表面軟質ウレタン6Aの混合液を真空装置8に入れて脱泡作業を施す。そして裏面側型Rと表面側型Fとを対向させてこの隙間内に内部用軟質ウレタン6Cの混合液を流し込み、テーブルサンゴ複製物99を製造する。【選択図】図14
