An impeccable flexographic printing press that stands out for its high degree of versatility maintaining the ergonomics and usability features of the F2 range.
Main benefits for you
Faster setpoints, less shrinkage, more benefits : The job changeovers in flexo presses generate waste in web and inks that have a significant impact in the profit and loss account. The current trend to reduce runs implies more changeovers, an increase in the total waste generated during the setpoints and a loss in machine efficiency.
At Comexi we have launched a set of solutions that adapt to the difference scenarios facing our clients. The CINGULAR MODULES offer automatic and semi-automatic features, with or without a mark, adapted to the specific requirements of our industry.
Excellence with the most efficient cleaning system : The Comexi SelfCleaning is an automatic system that manages the ink supply to the print, and cleans the ink chamber, the anilox, ink tanks and connection hoses in the circuit. The system adapts to water-based inks and solvent-based inks.
Its high level of automation makes it possible to program different cycles (from light to intensive) to adapt solvent and time consumption to your needs. These advantages combined with the easy use thanks to the simple interface, complete a system designed according to the highest standards of efficiency.
The combination of bearing supports reinforced with larger diameter and the hydraulic axes carbon fibbers offer the most robustness possible against impacts. At the same time, allows high print quality at high speed.
The press has 8 decks adapted for a front print. Its design adapts to the easy access requirements for maintenance and daily operation thanks to the FLEXOEfficiency concept.
The doctor blade is assembled in a closed swinging chamber mounted on linear guides, with automatic horizontal movement by means of low friction, pneumatic pistons.
It is dismantled easily without having to disconnect the inking tubes, facilitating the cleaning and changeover tasks, with simple handling thanks to its extraordinary 12 kg weight. Thanks to the patented ComexiMAGNETBlade technology, a tool-free magnetic changeover system, we can obtain a fast and safe blade and seal changeover.
The plate cylinder and anilox sleeve changeover takes a couple of minutes. The covers are opened manually, in a quick, simple way.
The drying equipment is made up of two fully independent circuits which, via two blowers, blow hot air at high speed, evaporating the solvent or water contained in the ink.
The first circuit is used to dry between printing units. The screen can be removed freely from the machine by disconnecting the tubes from the inside, and the housing includes an inspection door, so maintenance is comfortable and easy. Both concepts are patented by Comexi.
The second corresponds to the drying tunnel, which is 5 m long. It is made up of sixteen drying boxes each one with a blower nozzle, with tubes arranged to optimise heat loss. The screens can be dismantled easily and do not need tools for cleaning. The tunnel includes an specific opening for maintenance and cleaning.
The Comexi F2 MP represents excellence in ergonomics and usability. It is fitted with a top diaphanous platform which provides access to all the elements requiring maintenance, highlighting the access to the set of rollers at the tunnel exit.
The F2 ML stands out for its accessibility. You can reach easily to all points of maintenance and cleaning without having to use ladders or work from high altitude. Drying screens can be folded to clean them quickly and you do not need any type of tool.
These are just some of the details that enhance this machine as the best solution in terms of maintenance for its easy handling, access to changing filters, lubrication points or decentralized electronic panels.
The press is designed so that most of the functions can be controlled from the control console. In parallel our COMPACT concept, based on the SIMOTION platform and in decentralising the electronics, provides for high electronic integration, thereby eliminating electronic equipment containers and facilitating maintenance tasks.
At Comexi we apply the DDDrive concept for driving the shafts via AC motors without any kind of mechanical transmission, controlled by absolute encoders coupled directly to the shafts. All improving the register and, consequently, the quality of the print.
The ENERGYSavvy concept, applied to a set of electrical and electronic control technologies, saves large amounts of energy and drastically reduces CO2 emissions.
