<P>PROBLEM TO BE SOLVED: To provide a sealing jig which can continuously mold a molding being a member having a bottom and a cylindrical part by being provided at the outlet side of an existing mold, a method having a separation membrane for manufacturing a bottomed cylindrical body using the sealing jig, and a ceramic filter in which the porous bottomed cylindrical body manufactured by using a raw material comprising ceramic powder. <P>SOLUTION: The sealing jig 1 is provided at the outlet side of the mold 9 of an extrusion molding machine 20 which can obtain a hollow molded body by extruding laminated ground and making it pass between the mold 9 and a core 13 and has a contact part 22 which can separate from/contact with the peripheral surface of the hollow molded body. By setting the sealing jig 1 on the outlet side of the existing mold. the molding being the bottomed cylindrical body 30 can be obtained continuously. Since molding efficiency can be raised, the jig is suitable for mass production. <P>COPYRIGHT: (C)2012,JPO&INPIT |
