Abstract

Described is a method of making a gasket for sealing in a print nozzle against a hostile liquid (e.g., ink). The improved gasket has application to inkjet printers in which fluid may be heated and/or charged as well as pressurized and may be corrosive to some plastic materials. In such environments, vibration, creep of materials and deformations may be experienced, testing the sealing qualities of the gasket.

Improved Gasket for Inkjet Printer

Described is a method of making a gasket for sealing in a print nozzle against a hostile liquid (e.g., ink). The improved gasket has application to inkjet printers in which fluid may be heated and/or charged as well as pressurized and may be corrosive to some plastic materials. In such environments, vibration, creep of materials and deformations may be experienced, testing the sealing qualities of the gasket.

As shown in Figure 1, a gasket 10 is formed with a printed circuit board-like material substrate 12 having regions 14 of metal cladding and a plated-through hole in the region surrounding an aperture 18 through which (side surfaces 16) ink pas The printed circuit board-like material of the substrate 12 could be a polyurethane or polyethylene material or an elastomeric material, all of which are stiff, but somewhat pliable and provide some dampening of mechanically induced vibrations and ultrasonic energy. The plated through hole provides a seamless connection in the region of the aperture and a controlled and uniform thickness to create a standoff between a nozzle plate and a print head.

Figure 2 shows a partial cross sectional view of the aperture 18, the metal cladding 14 and the side surfaces 16 on th substrate 12.
