i EHD Jet Technology

i EHD Jet Technology

Enjet's patented electrohydrodynamics (i EHD) jet technology has been applied for high resolution printing and coating by ejecting and atomizing ink and functional liquid using controlled electric field. Compared with conventional jetting technologies, it can realize nano-scale high resolution characteristics based on ultrafine size droplets. Enjet has supplied innovative products based on this EHD jet technology to many industries such as glass, mobile and display, automobile, bio-medical, pharmaceutical, and film.

i EHD Jet Printing

Enjet has developed innovative solution for high resolution & super-fine Printing technology, based on the iElectrohydrodynamic (iEHD) fluid control. iEHD jet printing is a near field jet printing (patented) technology using electrostatic field. Compared with the conventional EHD jet printing technology, iEHD allows more stable and reliable liquid ejection and dispensing.

Enjet developed novel iEHD(electrohydrodynamics) nozzle, precise manufacturing, and electrical pulse control technology, which enable to generate femtoliter (nanoscale diameter) droplets. iEHD-based Printers includes high precision nozzle, motion, dual nozzles, automatic focusing, stable ink supply, laser technologies, which allows super-fine patterns less than 1 ㎛ structures (line, dot, and complex shapes).

 

Drop-on-Demand Jetting and Printing

iElectrohydrodynamic (iEHD) jet printer can generate and eject super-fine droplets with relatively low viscous material and make patterns on 2D and 3D substrate by precise control of electric signal, motion, pump and valves. It can make super-fine dots and lines less than several micro-meters.

 

Continuous Jet Printing

iElectrohydrodynamic (iEHD) jet printer can continuously dispense high viscous material and make patterns on 2D and 3D substrate by precise control of electric signal, motion, pump and valves. It can make super-fine lines less than several micro-meters.

 

i EHD Jet Coating

Based on the iElectrohydrodynamic (iEHD) fluid control, we have developed innovative solution for high resolution & super-uniform coating. Our nozzle can atomize fluid into nanometer to micrometer droplets spray, and therefore form uniform thin films. The Enjets coating solution has many benefits as follows

 
  • Patented nozzle
  • High Throughput
  • Experience in many mass productions
  • AF/AS/AG/Hard Coating/Color Coating/PI
  • Specialized Fluidic Unit
  • Solution of Bubble Problem
  • Stable CSS(Chemical Supply System)
  • Material Savings: Up to 50%
