METHOD FOR MANUFACTURING LIQUID EJECTION CHIP AND LIQUID EJECTION CHIP - A simplified explanation of the abstract

This abstract first appeared for US patent application 18346974 titled 'METHOD FOR MANUFACTURING LIQUID EJECTION CHIP AND LIQUID EJECTION CHIP

Simplified Explanation

The abstract describes a method for manufacturing a liquid ejection chip with a sealing property between channels, even with downsizing.

  • Molten resin is filled into a mold with a substrate containing an ejection unit on one surface and grooves and protrusions for forming channels on the other surface.
  • The molten resin is cured to form a resin member on the protrusion, creating a partition separating adjacent channels.

Potential applications of this technology:

  • Inkjet printers
  • Medical devices for precise liquid dispensing
  • Laboratory equipment for fluid handling

Problems solved by this technology:

  • Ensures a sealing property between channels, preventing cross-contamination of liquids
  • Enables downsizing of liquid ejection chips without compromising performance

Benefits of this technology:

  • Improved accuracy and precision in liquid ejection
  • Enhanced reliability and longevity of liquid ejection chips
  • Cost-effective manufacturing process for liquid ejection chips


Original Abstract Submitted

A technique capable of ensuring a sealing property between channels even with downsizing is to be provided. A method for manufacturing a liquid ejection chip equipped with an ejection unit which is configured to be capable of ejecting a plurality of liquids, and a plurality of channels which are configured to separately store the plurality of liquids to be supplied to the ejection unit, includes: filling a molten resin into a mold into which a substrate in which the ejection unit is installed on one surface and a groove and a protrusion for forming the channels are formed on the other surface is loaded, and curing the molten resin, thereby forming a resin member on the protrusion with the molten resin, the resin member forming a partition separating a space within the channels adjacent to each other.
