e-Brick—GEW UV Curing System Technology Revolutionary Product

At the China (Guangdong) International Printing Technology Exhibition (Print China 2007), which has already ended successfully, the e-Brick GEW UV system is on display at the Nilpeter booth. Visitors followed and expressed their strong interest in this revolutionary technology product. Here we briefly introduce the e-Brick GEW UV system.

British GEW (EC) company, as a research and development base of UV ink curing system in the world, integrates research, design, manufacture, installation and after-sales service. With its superior quality and excellent service, it provides advanced UV to the world. Ink curing products. In the world, particularly in European and American markets, it enjoys a high reputation. Its products have been widely used in image printing, digital printing, metal decoration, coating, health care and other industries. Now GEW's UV curing system has gradually replaced inefficient heaters and ordinary drying units, becoming the mainstream of the UV curing market. And its partner in China, Nilpeter China Co., Ltd., is the office of Nilpeter, a world-renowned narrow-web rotary press manufacturer in China. Both parties are working together and have been working For the Chinese printers to provide the world's best UV curing system.

e-Brick UV curing system is the third generation technology of GEW. Compared with the previous two generations of technology, this technology has greatly improved energy saving, drying effect and equipment performance. For example, in terms of energy saving, we all know that an axis-driven eight-color flexographic printing machine consumes 60% or more of the energy consumed by the entire UV machine. The e-Brick UV curing system utilizes advanced electronic power supply technology to further refine power control and overcome many of the shortcomings of traditional control methods such as high power requirements and high power consumption. The e-Brick UV curing system has the following advantages:

High frequency square wave output High power and high power factor Standby low power output Stable square wave output Refined output power control

Figure 3 Electronic control voltage input and output

In our country, the frequency frequency is 50Hz. Figure 2 shows the output energy waveform of the lamp under the traditional control method based on the power frequency. We can easily find that the output of the UV lamp is 50 Hz as the traditional control method. The frequency fluctuates between 0 and the maximum value. Figure 3 shows the lamp output energy diagram based on the 300Hz electronic control. The electronic control method is a square wave control method that changes the power frequency to 300 Hz. After frequency conversion and waveform setting, both ends of the lamp will get a 300 Hz square wave voltage, so the lamp will output with a constant energy. As we look back at Figure 2 and Figure 3, it is not difficult to find that the same power input will also get more UV energy (Figure 4).
