Koenig and Bauer announces MetalStar 4

Koenig and Bauer has updated its MetalStar metal decorating press with the release of the latest version 4 model, which promises shorter make-readies and is said to be faster and more efficient than the MetalStar 3 that it replaces. It’s suitable food and chemical packaging as well as general commercial and closure applications.

Koenig and Bauer has introduced its new MetalStar 4 metal decorating press.

It takes sheets up to 1.2 x 1 metre and from 0.12 to 0.40mm thickness. It can handle plates up to 1220 x 1095mm with a maximum printing area of 1200 x 995mm. Depending on the configuration, the materials in use and the dryer unit, it runs at speeds of 6000 to 8500 sph, equivalent to 100 to 141 sheets per minute.

The new model features improvements in the feeder, with new sensors, newly designed blow pipes and scrapers, as well as adjustments to the infeed table to improve the reliability of the feeder. There’s a new touch panel on which the air setting can be made and stored for each job.

It comes with MetalControl, an inline colour measurement and control system that takes the operator through the colour setup for each print job. It can automatically set up the target densities in one print run and can also be used to print individual print runs as usual during set-up. MetalControl then makes a setting suggestion after each print run. During printing, it measures the ink densities on each colour patch in the print control strip or on individual colour patches and regulates the ink zones automatically every 10 sheets. There’s a new ErgoTronic console complete with a 23ins touch screen where all the settings can be applied. There’s an optional 75ins wall screen to display the measuring results from MetalControl and the individual zone openings in each inking unit. In addition, there are observation cameras mounted at strategic points in the line and this screen can show live images from these cameras.

It retains the short and dynamic inking and dampening unit and high-precision register printing of the MetalStar 3 thanks to the sheet travel in the gripper closure, as well as the extensive automation features. The fully automatic plate change FAPC (Fully Automatic Plate Change) is now even faster and has been equipped with a new infeed system that significantly enhances stability.

Each MetalStar 4 is customised directly to the individual needs of the customer and the application. Consequently, there’s a range of options including UV and UV-LED printing and inline coating plus various sheet handling modules and specialist packages.

It’s worth noting that Koenig and Bauer has sold some 400 printing units of the older MetalStar 3, which was introduced seven years ago. You can find further details on the new press from koenig-bauer.com.
