Title:
MANUFACTURING METHOD FOR NOZZLE PLATE, NOZZLE PLATE, MANUFACTURING METHOD FOR INKJET HEAD, INKJET HEAD, AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/034219
Kind Code:
A1
Abstract:
The present invention pertains to a manufacturing method for a nozzle plate, in which a substrate is press-punched to form a nozzle hole therein. The manufacturing method reduces sag width and better suppresses plastic deformation of the entire substrate, with a simpler configuration. This manufacturing method for a nozzle plate includes: a step for preparing a metal substrate having a thickness greater than 25 μm and a Vickers hardness of 250 HV or greater; and a step for press-punching the prepared substrate to form a nozzle hole for discharging droplets of a liquid.
