Hot Selling for Flexographic Printing Press - 8 color CI printing machine for woven bag – Changhong

Characteristic

• The machine introduction & absorption of European technology / process manufacturing, supporting / full functional.
• After mounting the plate and registration, no longer need registration, improve yield.
• The machine first mount plate, pre-trapping function, to be completed in advance prepress trapping in the shortest possible time.
• The machine is equipped with blower and heater, and the heater employed central temperature control system.
• When machine stop, Tension can be maintained, the substrate is not deviation shift.
• The individual drying oven and cold wind system can effectively prevent the ink adhesion after printing.
• With precision structural, easy operation, easy maintenance, high degree of automation and so on, only one person can operate.

technical specifications

Double station unwinding:

• Center-driven unwinding, equipped with magnetic powder brake, equipped with automatic tension control；
