==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.
