Vacuum metallizer for packaging

The BOBST K5 Expert, the next generation of the K5000 metallizer, can run at speeds up to 1200m/min, is available in widths from 2450mm to 3650mm and can house increased roll diameters of up to 1270mm to meet new industry trends for improved productivity. The K5 Expert houses the largest coating drum in the industry at 700mm which improves collection efficiency, reduces aluminium consumption and increases boat life.

The K5 Expert features a totally redesigned evaporation source providing a wide coating window, which translates into better coating uniformity and collection efficiency, minimising aluminium wire waste.

A more intuitive HMI screen and software interface make the machine easy to operate. The new design of the machine allows the operator to operate everything from the front of the machine and to be positioned much closer to view the evaporation source and metallization process through the strobe window; the new boat power controls are easy to operate and are located in front of each boat.

Another brand new feature is the automatic sequential control (ASC) system which speeds up start-up of the machine with minimum operator involvement.

In addition to the Bobstwinding mechanism based on “true tension” control, the new model incorporates low friction Ferrofluidic seals for an even better tension control on the rewind; all-in-all producing a virtually wrinkle-free roll-to-roll vacuum metallization process.
