A method of producing a fiber molded article using a pressing mold, includes inserting a first split and a second split into a slurry tank such that a fiber layer is formed on the first split and a fiber layer is formed on the second split, placing the pressing mold, which includes a solid elastic member and an inflatable elastic member configured to be inflated, onto the fiber layer on the first split, joining the first split and the second split such that a fiber molded article is formed from the fiber layer on the first split and the fiber layer on the second split, and dewatering and shaping the fiber molded article by pressing the fiber molded article by the solid elastic pressing member and the inflatable elastic pressing member.

Production mold for formed fiber

A molded body formed with pulp mold having projected lines corresponding to a slit-shaped vent package part, capable of being provided by paper-making/dewatering, using a paper making mold, a slurry having fibers dispersed in a liquid so as to obtain a three-dimensional fiber wetted laminated body, moving the laminated body to a dry mold having an inner surface with the slit-shaped vent package, and pressing and drying that laminated body.

Disclosed is a method of producing a fiber-molded hollow article by using a papermaking mold () composed of splits () which are joined to form a cavity () having two openings () connecting with the outside and an expandable pressing member () adapted to be placed in the cavity (). The method comprises the steps of immersing each of the splits () before being joined in a fiber slurry to form a fiber preform (), joining the splits () each having the fiber preform () formed thereon while placing the pressing member () in the cavity (), and molding and dewatering a molded article () in the papermaking mold ().

In a disk cartridge having an imbalance of the flow of resin at the time of injection molding due to the lateral asymmetry of recesses on which a shutter slides, the thickness of each shell of the disk cartridge is balanced laterally by forming a projection in one region which is the left half of the shell or the right half of the shell with respect to the center line C of the shell and occupies a larger part of the area of a shutter sliding recess and by forming a recess in the other region which occupies a smaller part of the area of the shutter recess.
