Coding Machine

The coding machine is controlled by the MCU with non-contact inkjet marking systems. By controlling its internal gear pump or machine external supply compress gases, to exert a certain pressure to the ink inside, the ink jet out through a tens of micrometers aperture nozzle. The crystal oscillator signal on the nozzle top will split continuous injection ink lines into ink drops with the same frequency, size, and pitch. And then the drops will be charged by electrode. The electrical quantity of the ink drops is decided by CPU. The tester will check whether the real electrical quantity accords to the phase. Finally, charged ink drop will deflex in the deflection electrode, jet out from the nozzle, and respectively print in different places on product surface to form a variety of text, patterns and so on. The uncharged ink drops will back to the recycling tank, and re-enter into the circulatory system of the coding machine .
