Abstract
A method for manufacturing an inkjet head having orifice plates with improved ink-repellent properties and durability, including the step of forming the ink-repellent film on the surface of the substrate by using the gas deposition process is provided.
Claims16
A method for manufacturing a water repellent member having a substrate and a water repellent film covering a surface of the substrate, comprising the steps of:
- contacting particles of a material having water repellent properties with an inert gas in a particle-generating chamber to form an aerosol of the particles;
- and
- transporting the aerosol of the particles through a particle-transporting pipe into a particle film-forming chamber and discharging the aerosol of the particles from a nozzle to the substrate to form the water repellent film on the surface of the substrate, wherein
- the particle-transporting pipe leads from the particle-generating chamber to the particle film-forming chamber.
