Brief Description
： Donghang F2 series medium web flexo
Printing machine is a high-end machine launched by Donghang. It can print web ranging from 830 to 1200 mm and coated paper, paperboard, non-woven fabric, light-weight coated paper, kraft paper, paper-plastic composite material, etc. This machine is widely used in paper cup, carton, food packaging bag, packaging paper, courier bag, milk carton, paper bag, nonwoven fabric and the like printing fields.
The F2 series medium web flexo printing features delivers the fastest set-ups and changeovers and shorter web path and fastest make-ready times in the industry. Additional advantages over traditional presses include short web paths, without adjusting pressure after changeover and minimal ink usage requirements resulting in waste savings up to 50% and fast changeover times for increased productivity. Its bearing bracket system overcomes the vibration in printing, making printing more stable and realizing the high precision printing. The max speed can reach 240m/min. On to the more advanced servo drives, this press provides pre-register function before starting and auto-register in printing, which support benefit creating for customers.
Main features: 1. Stable printing: specially designed bearer-type cam supports and fastens the plate cylinder with a locking hook, which effectively overcomes the vibration caused by plate gap and achieve high-precision and stable printing;.
2. Fast change of cylinders: specially designed bearer-type structure enables fast change of plate cylinders without adjusting printing pressure, which greatly improves production efficiency.
3. Short paper path design: design of short paper path greatly reduces production cost.
4. Pre-register function: servo-driving pre-registering function improves production efficiency and also reduces waste of printing materials in register debugging.
5. Accurate registering: accurate registering produces qualified prints in the acceleration and deceleration process.
6. Non-stop web unwinding and rewinding (optional function): printing materials can be changed during high-speed printing without power off, which improves production efficiency and reduces product costs.
