The work required for atomization increases in proportion to liquid flow rate, and high flow rates are required for high speed coating. It is for this reason that multiple guns are employed. Three regulated air supplies are used to govern the size, shape and intensity of air patterns generated by the spray array. Atomizing air provides the energy for liquid disintegration. Shaping air provides the energy for pattern flattening.
Liquid pressure provides the energy for liquid injection.
The multiple gun or spray array approach allows the DSA-2000 to operate with one spray pass per panel side. This fast application of the preferred volume of ink is the key to high production rates . Typical DSA-2000 output is between 90 and 120 panels per hour. The time to mix or reduce LPI material is outside of the operation times given. If the same ink is to be used, a container refill may be completed in 5 minutes.
