Abstract
A nozzle plate cutting off method for cutting off the nozzle plate from a primary processing plate including a frame body, a nozzle plate which has multiple nozzle holes for ejecting droplets and is separately arranged inside the frame body, and a connection portion arranged at a clearance between the frame body and the nozzle plate to connect the frame body to the nozzle plate. In the nozzle plate cutting off method, a punching tool is used to punch out the nozzle plate at a connection region of the connection portion with the nozzle plate, there by cutting off the nozzle plate from the primary processing plate.

A nozzle plate cutting off method for cutting off the nozzle plate from a primary processing plate including a frame body, a nozzle plate which has multiple nozzle holes for ejecting droplets and is separately arranged inside the frame body, and a connection portion arranged at a clearance between the frame body and the nozzle plate to connect the frame body to the nozzle plate,
- the nozzle plate cutting off method by which a punching tool is used to punch out the nozzle plate at a connection region of the connection portion with the nozzle plate, thereby cutting off the nozzle plate from the primary processing plate.
A method for manufacturing a nozzle plate formed with multiple nozzle holes for ejecting droplets, the method comprising:
- a formation step of forming a primary processing plate including a base portion, at least one plate portion separated from the base portion and a first connection portion connecting the base portion to the plate portion;
- and
- a first punching step of punching out a first connection region of the plate portion with the first connection portion;
- wherein the nozzle plate is manufactured from the plate portion cut out from the primary processing plate by the first punching step.
A method for manufacturing a nozzle plate having multiple nozzle holes for ejecting droplets in which a passage unit leading a liquid to the nozzle holes is attached on one face,
- the method for manufacturing a nozzle plate comprising:
- a formation step of forming a primary processing plate including a base portion, at least one plate portion separated from the base portion and a first connection portion connecting the base portion to the plate portion;
- and
- a first punching step for punching out a first connection region of the plate portion with the first connection portion from a specific face of the plate portion,
- wherein the specific face of the plate portion corresponds to one face of the nozzle plate to which the passage unit is attached, and
- the nozzle plate is manufactured from the plate portion cutout from the primary processing plate by the first punching step.
