Title:
PRODUCTION METHOD FOR PLATE-INTEGRATED GASKET
Document Type and Number:
WIPO Patent Application WO/2016/006366
Kind Code:
A1
Abstract:
Provided is a plate-integrated gasket production method that, when a gasket main body is integrally formed on one thickness-direction side of peripheral edge parts (11, 12) of a plate (1), can effectively prevent deformation of the peripheral edge parts (11, 12) of the plate (1), which are positioned inside cavities (43, 44). In order to achieve this purpose, a plurality of potting parts (23, 33) that comprise a rubber-like elastic material are formed at suitable intervals in the extension direction of the gasket main body so as to be positioned in formation regions of the gasket main body on one thickness-direction side (11a, 12a) of the peripheral edge parts (11, 12) of the plate (1), then the plate (1) is positioned, arranged, and closed inside a mold (4) such that sections that comprise the peripheral edge parts (11, 12) of the plate (1) and that comprise the potting parts (23, 33) are sandwiched and held between inner surfaces of cavities (43, 44) of the mold (4) and such that another thickness-direction side (11c, 12c) of the peripheral edge parts (11, 12) is in tight contact with one of the inner surfaces of the cavities (43, 44), and the cavities (43, 44) are filled with a liquid rubber material that is hardened.
