Abstract:
A process for producing a joined metal-resin plate body comprising:molding a resin plate by insert molding in such a way that an insert member having a through-hole therein is embedded in a resin with the outer periphery of the insert member being covered by said resin except for the faces thereof where said through-hole opens;fitting a metallic joining member, which has a through-hole therein of substantially the same diameter throughout the hole, and wherein said metallic joining member is adhered to a metal plate, into said through-hole of the insert member to superpose said resin plate on said metal plate;joining said metallic joining member with said insert member by applying pressure to the inner wall of said joining member to deform said joining member, said insert member and portion of said resin plate surrounding said insert member; wherein the amount of deformation is enough to join said joining member to said insert member and to eliminate gaps formed between said insert member and the surrounding resin during said insert molding, and wherein the deformation of said resin plate does not exceed the limit of elastic deformation of the resin; andsubsequently releasing the applied pressure to maintain a predetermined amount of elastic deformation of said surrounding resin after the release of said applied pressure.
