The working principle and adventages of thermal foaming inkjet printer

Along with the complexity and diversification of the market demand on product identification, inkjet technology has always been in the stage of continuous progress and development, which has derived many innovative inkjet technology, not only limited to the traditional continuous inkjet technology, but also laser inkjet, thermal foaming inkjet and other technologies, today, EC-JET will introduce the technology of thermal foaming inkjet coding machine.

Since barcodes, QR codes and other identification have relatively higher requirements for resolution (dpi), high resolution inkjet printers are also a more common type of inkjet printers in industrial processing and packaging. The thermal foaming inkjet printer is just one of the high resolution inkjet printers

The working principle of thermal foaming inkjet printer:

The thermal foam printer mainly uses a film resistor to heat the ink instantaneously (instantaneously heating to more than 300 ° C) in the ink ejection area to form countless tiny bubbles, which gather into large bubbles at a very fast speed and expand, forcing ink droplets to spray from the nozzle to form the required text, numbers, bar codes. If the bubble continues to expand, it will fade back onto the resistor; Bubbles disappear, the ink of the nozzle will shrink back, and then the surface tension will produce suction, and then pull new ink to the ink ejection area to prepare for the next cycle of printing, printing speed and high precision, printing effect for high-resolution text, numbers, barcodes, two-dimensional codes and patterns.

The application scenes of thermal foaming inkjet printer:

Thermal foam inkjet printer has great advantages in packaging identification and variable code printing, which is often integrated in packaging equipment such as rewinding machine, packaging machine or labeling machine and other automated platforms, which can spray print some common three-phase code content on labels or some permeable materials, and can also carry out large format variable information. Such as common QR code, barcode, multi-line pattern, multi-line text digital identification and other content, printing speed is fast, high resolution can achieve similar effect of industrial printing font, the fastest speed can reach 200m/min.

The adventages of thermal foaming inkjet printer:

Different from the traditional small character inkjet printer, the thermal foaming inkjet printer is simple to operate, easy to install, powerful printing function, can print real-time data, barcode, QR code, database and other content, powerful editable function; On the other hand, the application of thermal foaming inkjet machine is more environmentally friendly, thermal foam inkjet machine does not need to use solvent, cleaning liquid, no ink supply system, eliminate ink pollution, zero influence on the environment, ink cartridge installation and replacement is convenient, easy to operate, simple maintenance.
