Publication number: 20080047636Abstract: Method of manufacturing a metal gasket including a base plate having at least fluid passage holes and circular beads surrounding the fluid passage holes, the base plate being formed by providing a rubber coating layer on a surface of a metal plate with a base coat and an adhesive interposed therebetween. A metal plate having low-temperature age-hardening characteristics is used as the metal plate of the base plate. After the base coat is applied to the metal plate and dried at a temperature lower than a low aging temperature of the metal plate, press-working of the circular beads is performed on the metal plate. Thereafter, the metal plate is age-hardened while burning the base coat at the low aging temperature of the metal plate. A metal gasket having excellent durability and circular beads which are hardly broken even when crushed, is obtained.Type: ApplicationFiled: August 23, 2005Publication date: February 28, 2008Inventors: Hiromitsu Sasaki, Norifumi Misumi, Takashi Yajima, Masabumi Miyashita, Takashi Katsurai, Tadao Nishiyama, Yasunori Murakami
