Abstract: In order to achieve lower costs in a molding apparatus using a mold by reducing mold cleaning steps following releasing of the product from the mold and shortening the molding cycle, the apparatus is equipped with a plurality of fixed molds and movable molds which are heated to the temperature necessary to harden a molding material and come together by means of clamping to form a cavity, and a non-heated cold runner which supplies the molding material from an injection device to the interior of the cavity via a gate opened in the movable mold, the fixed molds and movable molds being movable between an injection stage where the injection device and cold runner (32) are present and an opening stage near the injection stage.

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.

Abstract: The invention provides a gasket which improves a handling workability of a rubber only type gasket. The gasket of the invention is constructed by a combination of a rubber only type gasket main body, and a carrier sheet which is made of a resin film retaining the gasket main body in a non-bonded state, and the carrier sheet is provided with an air inflow port for making air flow into a portion between the carrier sheet and the gasket main body when the gasket main body is detached from the carrier sheet. A gasket retention portion having a three-dimensional shape which is deformed along an outer shape of the gasket main body is arranged at a position which laps over the gasket main body in a plane in the carrier sheet, and the gasket main body is partly accommodated within the gasket retention portion in a thickness direction.

Abstract: The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

Abstract: The purpose of this invention is to make it easy to handle all-rubber gaskets. To achieve this purpose, a gasket is characterized in that a gasket body of only rubber is combined with a carrier film that is made from a resin film to hold the gasket body in a non-adhesive state. A three-dimensional portion having a shape that is deformed along the external shape of the gasket body is provided at a position where the gasket body and a plane of the carrier film overlap, and a portion of the gasket body is contained in the three-dimensional section. The gasket body is used as a gasket for fuel cells incorporated into a fuel cell stack.
