Abstract
A nozzle plate contains nozzles, liquid chambers and connection channels between liquid chambers and supply containers for the liquid. All the function regions are produced integrally as a microstructure body by casting from one or more microstructured mold inserts. The smallest implementable spacing of the nozzles from one another can be considerably smaller than in the previously known plates, which allows increased printing density.
Claims4
A method of making a nozzle plate having a plurality of functional regions for a liquid jet print head, comprising the steps of:
- forming a metal mold insert, said mold insert having a microstructured configuration complementary to a nozzle plate to be produced;
- and
- casting a nozzle plate having at least one nozzle from the mold insert in one single production step, and said nozzle plate containing all functional regions within an integral microstructured body.
A method of making a nozzle plate having a plurality of functional regions for a liquid jet print head, comprising the steps of;
- forming a metal mold insert, said mold insert having a microstructured configuration complementary to a nozzle plate to be produced;
- and
- casting a nozzle plate having at least one nozzle from the mold insert, wherein said forming step comprises a lithographic forming technique.
