  • Method and apparatus for manufacturing a nozzle plate for ink-jet printers
    Patent number: 4574445
    Abstract: Nozzles are formed in a plate for an ink-jet printer by holding a metal foil tightly against the side of the plate from which the nozzle is to protrude, and then pressing and punching through the plate and the metal foil together, through an aperture of a pressing die into a cushion of a hard elastic material such as lead. The foil is made of an isotropic material which is harder than that of the nozzle plate, and is preferably an amorphous or microcrystalline metal.

  • Method of and device for manufacturing an ink jet printer
    Patent number: 4434350
    Abstract: The pressure chambers (2) for the ejection of the ink are recessed in a body (9) of an ink jet printer. The chambers (2) are covered by a metal diaphragm (1). The pressure chambers (2) and the associated narrow passages (4) are formed in the body (9) by depression. Subsequently, the metal diaphragm (1) is connected to the body (9) by energy beam welding. The energy beam (31) is moved along the edges of the pressure chambers (2) and of the narrow passages (4). An electron beam or a laser beam may be used as the energy beam (31).

  • Method of and device for manufacturing a jet nozzle plate for ink jet printers
    Patent number: 4425777
    Abstract: To manufacture a jet nozzle, the nozzle plate is first drawn through a drawing ring of spring steel in one operation by a press and punch die having the internal dimensions of the jet nozzle, the plate subsequently being punched during further drawing in a hard elastic plastic block which serves as a cutting cushion. The drawing ring is then slightly pressed into the plastic. All parts of the press and punch tool which are subject to the pressure exerted by the die and the die itself have been polished to be free from hair lines.
