摘要： A metallic plate member having at least one through hole to be a part a common liquid reservoir of a liquid ejection head is provided. In a first die, a plurality of first projections are arrayed in a first direction with a fixed pitch. Each of the first projections is elongated in a second direction perpendicular to the first direction. The plate member is mounted on a second die, and a regulating member is inserted into the through hole. The first projections are pressed against a first region in a first face of the plate member which is adjacent to the through hole in the second direction, so as to generate a plastic flow of a material in the plate member into gaps defined between the first projections, while the plastic flow is regulated by the regulating member. A plurality of recesses formed by the first projections and a plurality of partition walls formed by the material flown into the gaps constitutes a part of the pressure generating chambers.

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.
