摘要： A die apparatus is composed of a lower receiving die, a round punch having the shape of a fine hole, and PET provided between the lower receiving die and the round punch. The round punch is passed through a work plate placed on the PET to cause a punched-out piece to remain within the PET, thereby boring the fine hole. The work plate having such fine holes is thus easily prepared, and applied as a filter for a liquid-jet head.

摘要： An object is to provide a fine forging method for forming partitions of recesses precisely and forming recess shapes for pressure generation chambers etc. with high accuracy as well as a liquid ejection head that is produced by using the fine forming method. A fine forging method for forming groove-shaped recesses that are arranged at a prescribed pitch. After groove-shaped recesses are formed tentatively in a material plate by a first punch in which tentative forming punches are arranged, finish forming is performed on the tentatively formed groove-shaped recesses by using a second punch in which finish forming punches are arranged. An end portion of a projection strip is formed with slant faces or a slant face, whereby an end portion of each groove-shaped recess is formed precisely. A liquid ejection head produced by the above method exhibits stable liquid ejection characteristics and its manufacturing cost can be reduced by virtue of simplified working of forging.

摘要： There is provided a first die, in which a plurality of projections are arrayed in a first direction with a fixed pitch to form at least one array of the projections. Each of the projections is elongated in a second direction perpendicular to the first direction. The first die faces a first face of the plate member. A second die is opposed to the first die while supporting a second face of the plate member. At least one first region is formed on the plate member so as to have a less rigidity than another region of the plate member. The first die and the second die are approached so that the projections are dug into a second region in the first face of the plate member, thereby forming partitioned recesses to be pressure generating chambers of a liquid ejection head. The at least one first region is adjacent to at least one of ends in the first direction of the second region, such that the first region and the second region are arranged in the second direction.
