<P>PROBLEM TO BE SOLVED: To provide a gasket molding method capable of preventing an impregnating area line of a sealing material G from becoming an undulating shape and thereby accurately linearly forming the impregnating area line to stabilize seal performance, in a method for molding a gasket part 4 by impregnating a sealing material G into a peripheral part of a porous body 3 such as a GDL. <P>SOLUTION: In this gasket molding method for molding a gasket part 4 by impregnating the sealing material G impregnated into a peripheral part of a porous body 3 toward an in-surface direction of the porous body 3, by using a die 11 provided with a groove-like sealing material accumulation part 15 formed along the peripheral part of the porous body 3 around a cavity space 14 for inserting the porous body 3 therein and provided with a required number of injection gates 16 in the sealing material accumulation part 15, the sealing material G is injected into the groove-like seal accumulation part 15 from the injection gates 16 and the sealing material G injected into the groove-like sealing material accumulation part 15 is impregnated into the peripheral part of the porous body 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
