DOSUN UV-FINATM Laser Engine: Integrating several high technologies, such as high-power laser diode, 32-64 channels fiber coupling, optical power balancing, constant temperature controlling by TEC and so on, output resolution 720dpi, can manufacture complex moire patterns.

By using semiconductor constant temperature controlling, the machine can work for a long time under the ordinary room temperature.

Optical power balancing system can optional sets laser intensity, adjusting the balance of each laser power  automatically, in order to achieve the best exposure efficiency, extend the using life of laser diode.

Characteristics 

·The UV technology of laser direct imaging is directly imaging on the surface of traditional UV sensitive emulsion. Because of don’t need film and ink, so the cost is low, and convenient, environmental protection.

·DOSUN UV-FINATM Laser Engine: Integrating several high technologies, such as high-power laser diode, 32-64 channels fiber coupling, optical power balancing, constant temperature controlling by TEC and so on, output resolution 720dpi, can manufacture complex moire patterns.

·By using semiconductor constant temperature controlling, the machine can work for a long time under the ordinary room temperature.

·Optical power balancing system can optional sets laser intensity, adjusting the balance of each laser power  automatically, in order to achieve the best exposure efficiency, extend the using life of laser diode.

·UV laser engraving technology is a fast engraving technology.The speed of engraving is depending on size of power and number of ray path. DOSUN UV-FINATM laser engine can achieve 64 paths, which provide 16 paths for print engraving.

·UV laser engraving is a low carbon, environment protection technology.

Low power: 1.5

No consumable items: Do not need film, ink, wax

Low cost: the function of sensitive emulsion is basically same with traditional, the price also basically same.

·UV laser engraving is a “friendly” engraving technology. The manufacture process is not only as same as traditional process, but also more convenient. Basing on the design principle of “convenient, practical, reliable, advanced”, in the process of engraving image, the equipment provides monitor display, operation help and so on. By using the software and hardware, it all can reflect a “friendly” attitude to operational workers.

·UV laser engraving is a real photo etching technology, using on the paper offset print, DOSUN UV-FINATM Laser Engine can achieve 2400dpi, making the line of 0.01mm, showing the net-point of 1%~99%, it can provide the 720dpi for print engraving, on the “continuing” neurogen ( offset plate), it can manufacture the line of 0.035mm. Because rotary engraving isn’t “un-continuing” neurogen, now, the highest mesh number is 195 meshes, in theory, we can achieve the smallest line for 0,13mm, in the manufacturing, we usually use 125 meshes, in theory, and we can achieve the smallest line for 0.21mm (Data for STORK Company).
