Frequently Asked Questions

8 Colors Ci Central Drum Flexo Printing Machine Technical Service

1. What materials are suitable for this Central Drum Flexo Printing Machine?

This machine is specifically designed for flexible packaging printing. It is highly suitable for printing on plastic films, paper, nonwoven fabrics, and various composite materials.

2. What is the maximum mechanical speed and practical printing speed?

The machine features a maximum mechanical speed of up to 500 m/min, with a maximum operating printing speed of 400 m/min, depending on the inks, printing plates, design layouts, and substrate materials used.

3. How does the direct drive torque motor improve performance?

By using a torque motor to directly drive the center impression drum, the system completely omits traditional transmission gear components. This achieves a color registration accuracy of within ±0.1mm and reduces maintenance costs by approximately 30%.

4. How is the temperature controlled on the central impression cylinder?

The central cylinder has a double-wall design that allows constant water flow throughout the CI surface. A closed-loop temperature control system regulates both heating and cooling to maintain a stable operating temperature of 30°C ± 1°C.

5. What type of ink systems and drying methods are supported?

The machine supports both water-based ink and solvent-based ink. It utilizes an electrical heating dryer system capable of reaching a maximum oven temperature of 80°C.

6. What are the key features of the unwinding and rewinding systems?

It features a turret-type non-stop unwinding and non-stop rewinding system that handles reels up to 600 mm in diameter. It is equipped with a floating roller device, low-friction cylinder, and encoder for constant tension control between 20 N and 300 N.
