  • Patent number: 10625445
    Abstract: Disclosed is a method for manufacturing a substrate-integrated gasket using screen printing. The method includes: a step for forming, on a surface of a substrate by means of screen printing, a coating layer of a paste for forming a gasket; and a step for hardening the coating layer by pressing, at a predetermined height, a coating layer correction member to the coating layer. The cross-sectional shape of the coating layer formed on the surface of the substrate is corrected by means of the coating layer correction member, and in such state, the coating layer hardens to be a gasket, thereby forming a gasket having a highly accurate cross-sectional shape.

  • Publication number: 20200096109
    Abstract: A film-integrated gasket is provided in which a gasket body is supported by a gasket support body formed of a resin film and a film thickness t2 at a position where the gasket body is supported is set to be smaller than a film thickness t1 at an adjacent position thereto so as to satisfy a demand for low reaction force by reducing the compression ratio in the thickness directional in mounting. The film-integrated gasket can be provided with a portion compressed in the thickness direction at the position where the gasket body is supported, so that the portion sets a thickness difference. The film-integrated gasket can alternatively be provided with a portion where a plurality of resin films is stacked at an adjacent position to the position where the gasket main body is supported, so that the portion sets a thickness difference.

  • Publication number: 20200096110
    Abstract: When a carrier film is removed from a gasket body of a carrier-film-equipped gasket, in order to easily remove the gasket body adhering to the carrier film from the carrier film, the adhesion area of the gasket body and the carrier film is reduced as a preliminary process of a peeling process of peeling the carrier film from the gasket body against adhesive force in a state where the gasket body is fixed to a base, and then the peeling process is implemented in the state where the adhesion area is reduced. When the gasket body is pressed from the carrier film side with a pressing protrusion portion of a pressing portion, the pressing is performed after the positioning on the plane is performed with positioning means by recess/projection engagement provided beforehand between the pressing portion and the carrier-film-equipped gasket.
