PROBLEM TO BE SOLVED: To provide a method and device for wet molding which give a product with a quality equal to or better than that of an FP (Filter Press)-molded one and is composed of a production line that requires little workload associated with color changes, etc., needs a small number of people to operate, copes with all the production needs from small to large lots, is mold-free, inexpensive and compact, and a high quality product obtained thereby.SOLUTION: The molding device includes a blocking and excess filling step in which while the opening of a space for filling involving an inner tray 1 being a container to be filled is blocked, a fluid filling material is filled into the space in an amount exceeding the volume of the inner tray and a press step in which an overflow-preventive press frame is fitted along the edge of the opening, a press head slidably arranged in the frame presses the surface of the filling material so as to put the material including the excess portion into the inner tray.COPYRIGHT: (C)2010,JPO&INPIT【課題】FP成型と同等以上の品質が得られ、色替え等の手間も少なく、少人数で稼動でき、小ロットから大ロットまですべてに対応可能で、金型不要で低コストで且つ、コンパクトな製造ラインからなる湿式成型方法及び装置及びこれらによって得られる高品質な製品を提供する。【解決手段】被充填容器である中皿を含む被充填空間の開口部を閉塞しつつ空間に流動性の充填物を、中皿1の容積を上回って充填する閉塞増量充填工程と、予め洩出防止プレス枠を開口部の縁に沿って装着した後に、枠内において摺動自在に配置されたプレスヘッドによって充填物表面を押圧して、増量充填分を含めて中皿内に収めるプレス工程とを含むことを特徴とする。【選択図】図3
