About an hour's drive from Prague in the Czech Republic, you find a small town called Všetaty. One company stands out in the aerial photos: Thimm Packaging Srl. We soon realize this is a massive factory as we approach the company. The roads can barely manage the heavy traffic needed to bring raw materials to the site and finished corrugated boxes to the company's customers. Let the tour begin!

By Editor Morten B. Reitoft

We went to Všetaty because four years ago, Thimm decided to invest in a Highcon Beam 2C, and I will write more about it in a moment, but for context, let me explain more about Thimm Packaging. In a way, the company is simple. Raw materials in - finished boxes are out, but when you visit the site, you soon realize that how this production is designed and operated is, in my view, unique.

At one end of the building, you find a BHS Courrugater line capable of producing almost any corrugated material; if you haven't seen a corrugator line before, the size will surprise you. It's (and I am guessing) 50-70 meters long, 5-6-7 meters wide, and maybe 5-6 meters tall. I wish I had measured it because when you see it, the size does surprise you. The machine can produce up to almost 300 meters per minute, and as if this wasn't enough, the finished boards are delivered directly to an automated 'floor' that moves the stacked boards in all directions.

The stacks of the boards are registered in a computer automatically and brought directly to the flexo-printing machines from BOBST and Göpher that not only print but also die-cut the sheets, deliver them to a palletizer or a robot, pack and wrap the finished products, and then again moved automatically to either the gluing department or to the warehouse where the goods are soon delivered to the customers.

To see this in real life is simply amazing. The 350 employees deliver production around the clock. When I ask about the utilization of the machines, Plant Manager Kamil Mašek and I talk about bottlenecks - and funny enough, before the new BHS corrugator was installed, the bottleneck was on making the sheets. Now the bottleneck is the printing machines, and every time a new piece of technology is installed, the bottleneck changes.

The printing machines run three shifts, the corrugator two shifts, and the group is busy. Millions of m2 are produced annually, and almost everything has never been touched by humans - and it's in this context we see the always easy-to-recognize Highcon Beam 2C.

The first time I saw a Highcon was years ago with a Swedish Packaging company, Gafs Kartong. I was amazed as they showed me an amazingly complex design for a luxury Apple juice product (as far as I remember). The box was covered with cut-out circles making the box very beautiful and, at the same time, totally impossible to do with a die-form. Later at drupa, Highcon exhibited showing women dressed in unique dresses made of paper, and Highcon almost became a synonym with paper art - and less industrial-scale production. Later, I visited Autojon in France to see another Highcon machine in a packaging company. No question that Highcon at this time was established as a 'haut couture' finishing device capable of producing remarkable things, but Highcon wanted their technology to be seen and accepted as an industrial-scale completing device. Today it is, and when you visit the technology at a company like Thimm, you understand that the machine serves some impossible purposes!

The Beam 2C is a laser-cutting finishing machine made for corrugated cardboard. With three lasers that can deliver different energy densities, the Beam can be set to do many things impossible conventionally. In the upcoming video from Thimm, we will show you a few things that might be of interest: No pressure is put on the substrate, and the structures are intact and, therefore, can hold more weight. That is, of course, nice, but it allows the customer to lower the thickness of the board, potentially reducing the price or giving more creative possibilities.

Inside all Highcon machines (Euclid and Beam), you find something called DART, which is short for 'Digital Adhesive Rule Technology.' DART eliminates the need for dies for creasing lines, etc., as Highcon can 3D print the creasing lines using a polymer-based material on a film inside the machine. When the DART is printed, it's dried using UV light and immediately ready to be used. The entire process on the forms we saw took about 3-4 minutes, so super cool and reduced time considerably.

Time is an important parameter, and so is speed. With a max speed of about 2,500 B1 sheets per hour, the Beam 2C is considerably slower than a traditional die-cutter, but still, Thimm uses the Beam 2C for longer runs and short and specialized jobs. The setup time is one important parameter, but also other parameters play a role. With the combination of laser and the previously mentioned DART, you can create products with a perforation in the creases and many more options.

When I spoke with Kamil Mašek, the Beam 2C gave Thimm many opportunities, like short-run work, added value finishing, new types of customers, and last but not least, an improved competitive situation. What I also learned from the conversations with Kamil Mašek, he believes the future is digital - and sees machines like the Beam 2C as a viable future, especially as he thinks they will develop machines for larger formats, maybe even faster - and therefore, a future where conventional finishing will be more digital - exciting to learn, of course :-)

Seeing the Highcon Beam 2C in a working environment like Thimm's is interesting as Highcon now clearly shows that their technology is industrially grated, which will open up more opportunities.
