20080314108 | PRESSING METHOD, METHOD OF MANUFACTURING PUNCHING PLATE, PUNCHING PLATE, AND LIQUID EJECTING HEAD - A pressing method by which through holes are formed using a punch in a target plate material having a first face and an opposite second face. When the target plate material is punched with the punch from the second face in such an orientation that the first face of the target plate material is in contact with an elastic base, depressed portions are formed. The depressed portions are curved toward a direction in which the through holes are punched to sink downward in the form of funnel as they approach peripheries of the through holes, and are located at peripheral portions around the through holes that are formed in the target plate material in such a manner that the peripheral portions are pushed in toward a deeper side in a thickness direction of the base against an elastic force of the base and are deformed. | 12-25-2008 |
