PROCESS FOR PRODUCING METALLIC GASKET |
摘要 |
A process for producing a metallic gasket, which comprises making a thin metallic sheet into a solid figure having an inclined surface, thereby providing a bead region extended upwardly and downwardly over the inclined surface, and forming a sealing part made of a hardened rubber layer on the surface of bead region, characterized by forming a sealing part extended from the apex of the bead region down to an upperward position on the inclined surface, and another sealing part extended from a downward position on the inclined surface down to the flat bottom part, and joining the sealing parts by the rubber material in a solution state extended along the inclined surface from both of the sealing parts, before drying and hardening of the material for making sealing parts. Application of the rubber material in a solution state is carried out preferably by a screen printing process. The rubber sealing parts formed by a silk screen printing process contributes to uniformization of the layer thickness resulting from the drying and hardening. |
