Throughout the industrial development of piezoelectric print heads

In the past 10 years, printing industry, industrial piezoelectric nozzle technology is a significant development and progress. From the original simple label printing to wide format printing, large format from low precision to high precision output, industrial piezoelectric nozzle technology led the printing industry leap again and again.

HC screen Special Indian network In Inkjet Industry market piezoelectric nozzle influential companies are British XAAR company, Spectra Corporation, Japan and the Japanese Seiko SPT Konica Corporation, the following brief were produced for each nozzle.

A British XAAR XAAR company’s main nozzles are XAAR128, XAAR500, XAAR126 and XAAR128 + versions.

1, XAAR128 Purcell nozzle is the first company markets the most widely used is the print head, there are three models:

XAAR128-200, 200dpi, 0.54 m / s

XAAR128-360, 360dpi, 0.39 m / s

XAAR128XL, 360dpi, 0.59 m / s

This type nozzle 128 channels of internal mesh filter larger particles much as 80PL blot around. In addition, this nozzle poor adaptability to the outside world can not change because of temperature to control the spray voltage through software, so the service life compared with other heads greatly reduced.

2, XAAR500 Purcell nozzle is used, stability and maneuverability of the best nozzle, the width of the Deputy for the 70mm, there are 500 channels, its resolution mode, there are two:

XAAR500-180 type of speed up to 0.51 m / s, droplet size 80PL

XAAR500-360 type of speed up to 0.56 m / s, droplet size 40PL After following the XAAR128

XAAR500 developed a highly integrated nozzle, the manufacturing process has also greatly improved the hole number and the service life increased nearly 4 times higher than XAAR128. XAAR500 increase with Electronic Switching different Ink Function, with a spray can for the order of the different printed a different color ink system. Its advantage is also reflected in the easy to install, simple chromatography, because it has two resolution modes, it has a different gray level. However, the higher its market price, the domestic retail to 20,000 / only. God made machine win the lottery done by XAAR500 series of very successful, but the conflict with the domestic printing market prices higher, so its market share is relatively small.

3, XAAR126 following the XAAR128 and XAAR500 launch of a highly integrated nozzle, it retains the characteristics of low-cost XAAR128 nozzle, but also inherits the advantages of long life XAAR500 the same time, the software have adjustable nozzle voltage of the advantages . XAAR126 specific advantages in the following areas::

A, accuracy and speed improved. XAAR128 most accurate 360DPI, and XAAR126 accuracy up to 400DPI, fast running speed of 660 mm / sec. And XAAR128 biggest difference is that electronic switching ink without having to replace the nozzle. Fluctuations in the internal control system has to make in the acceleration or deceleration of the process, the ink appears on the print fluctuations impact to a minimum.

B, to adapt to strong performance. XAAR126 with advanced control features that can change with external factors, be flexible and easily adjust and control.

C, installation and maintenance. XAAR126 has a unique design framework and specific modules, so that the use of the installation and proofing process is very simple and convenient. Meanwhile, the nozzle was designed out of two ports, eliminating the need generated by the installation or replacement of the filling nozzle and replace the ink and other procedures.

D, stability and cost. XAAR126 the basic life of the nozzle more than one year, more long-term maintenance of proper life, because in the production of which has a good adjustable performance, off Mexico, fly spray ink, and burning have greatly reduced the phenomenon, print screen more stable. According to the present market Sell Prices, the cost prices XAAR128 more competitive price.

4, XAAR128 + Purcell’s most recent XAAR128 is based on the newly developed varieties, the pipeline for the 360 holes.

A, limitations. Because of its sprinkler heads with XAAR128 similar, but with XAAR128 and XAAR126 nozzle compared to the pipeline and close more of the requirements of the ink is very harsh, often breaking the phenomenon of ink, domestic ink used for the very few manufacturers, is XAAR128 and XAAR126 2 times the cost of ink, ink prices high, is its greatest limitation. Another nozzle height is the biggest limitations that affect their use of one of the factors, XAAR128 + nozzle height can be adjusted very end, if the mechanical properties of the design shall not be deemed, in the output of large screen, it often appears blown nozzle phenomenon.

B, stability. Produced by Purcell heads the company Teflon material used in all manufacturing, so XAAR128 + using the stability can not guarantee the accuracy of its use after 3 months will be the first mate was reduced, or even impossible to produce.
