Inkjet Printing
Piezoelectric printheads elements function by deforming a piece of piezo in proportion to the voltage applied to force droplets of ink to be released. CTS supplies piezoelectric printhead elements in two types: bend mode or shear mode.
The repeatability of the piezo element to produce uniform ink drop size is one of the most important performance requirements for inkjet printheads. Additional requirements include compatibility with the type of materials being dispensed by the inkjet process, the life of the printhead in printing applications as well as the ability to produce fine pitched electrode patterns.
CTS piezoelectric elements are well suited for industrial printhead applications as they have excellent property stability over years of manufacturing, the electrode layers can be formed using photolithograph processes supporting the fine pitch requirements for this application and mechanical strength and machinability are excellent for this application.
CTS recommends piezoelectric material types 3195HD, 3203HD, 3221HD and 3222HD for industrial inkjet printing applications.
