摘要： A male die for forming a member incorporated in a liquid ejection head is disclosed. Each of a plurality of first forging punches is operable to form a first recess on a metal plate. The first forging punches are arranged at a fixed pitch to form a punch row in a first direction. Each of a plurality of second forging punches is operable to form a second recess on the metal plate. The second forging punches are arranged adjacently to first forging punches located at both ends of the punch row. The first recess is to be a first part of the member which is used to eject liquid from the liquid ejection head, and the second recess is to be a second part of the member which is not used to eject liquid.

摘要： In order to manufacture a liquid ejection apparatus, a metal board is prepared. The metal board is subjected to a plastic working to form a plurality of recesses on a first face in a first region of the metal board. Through holes are punched so as to communicate the recesses and a second face of the metal board. The metal board is subjected to a plastic working to form a plurality of dents in a second region of the meal board. A metallic nozzle plate formed with nozzles is joined onto the second face of the metal board, such that each of the nozzles is communicated with one of the through holes.

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： A liquid-ejecting head includes a channel which is in communication with a nozzle opening and which includes a pressure-generating chamber, a circulation channel that serves to circulate a liquid in the channel, and a pressure generator that serves to generate pressure change. The circulation channel has a narrow portion including a first wall and a second wall, the first wall tilting with respect to a forward direction of a liquid flows and serving to gradually decrease the cross-sectional area, the second wall tilting with respect to the flow direction and serving to gradually increase the cross-sectional area. The tilt angle of the first wall with respect to the inner surface of the circulation channel is larger than the tilt angle of the second wall with respect to the inner surface of the circulation channel at the downstream side.
