Title (EN) METHOD FOR MANUFACTURING SUBSTRATE-INTEGRATED GASKET
(FR) PROCÉDÉ DE FABRICATION D’UN JOINT D’ÉTANCHÉITÉ INTÉGRÉ À UN SUBSTRAT
(JA) 基板一体型ガスケットの製造方法
Abstract:
(EN) A method for manufacturing a substrate-integrated gasket that does not require air vents to be provided extending from a cavity in a mold and thus does not require a post-process for removing flash that forms in the air vents comprises: a coating step of coating a front surface of a substrate (1) with an adhesive in a prescribed pattern corresponding to an extended shape of a gasket to be molded; and a step of filling and curing an uncured molding material in a cavity (40) that is defined between the substrate (1) and an inner surface of a mold (10) by mounting and clamping the substrate (1) inside the mold. The coating step includes forming a main adhesive coated region (31) extending along an extending direction of the cavity (40), partial adhesive coated regions (32) capable of closely contacting the mold (10) outside the cavity (40), and non-adhesive coated regions (33) extending from a position outside the cavity (40) to a position inside the cavity (40).
(FR) La présente invention concerne un procédé de fabrication d’un joint d’étanchéité intégré à un substrat qui ne nécessite pas la fourniture des orifices de ventilation d’air dans le prolongement d’une cavité dans un moule et ainsi ne nécessite pas de post-procédé pour retirer l’éclair qui se forme dans les orifices de ventilation d’air comprenant : une étape de revêtement pour le revêtement d’une surface avant d’un substrat (1) avec un adhésif dans un motif prescrit correspondant à une forme étendue d’un joint d’étanchéité à mouler ; et une étape de remplissage et de durcissement d’un matériau de moulage non durci dans une cavité (40) qui est définie entre le substrat (1) et une surface interne d’un moule (10) par montage et serrage du substrat (1) à l’intérieur du moule. L’étape de revêtement consiste à former une région adhésive principale revêtue (31) s’étendant le long d’un sens d’extension de la cavité (40), les régions revêtues adhésives partielles (32) aptes à entrer étroitement en contact avec le moule (10) à l’extérieur de la cavité (40), et les régions revêtues non adhésives (33) s’étendant depuis une position située à l’extérieur de la cavité (40) vers une position à l’intérieur de la cavité (40).
(JA) 金型にキャビティから延びるエアベントを設ける必要がなく、このためエアベント内に形成されるバリを切除する後工程も不要とした基板一体型ガスケットの製造方法であって、成形すべきガスケットの延長形状と対応する所定のパターンで基板(1)の表面に接着剤を塗布する塗布工程と、基板(1)を金型内に設置して型締めすることにより基板(1)と金型(10)の内面との間に画成されるキャビティ(40)に未硬化の成形材料を充填して硬化させる工程と、からなり、塗布工程において、キャビティ(40)の延長方向に沿って延びる接着剤の主塗布領域(31)と、キャビティ(40)の外側で金型(10)と密接可能な接着剤の部分塗布領域(32)と、キャビティ(40)の外側の位置からキャビティ(40)の内側の位置に達する接着剤の非塗布領域(33)を形成する。
