If your plant makes boxes and you want printing, slotting and die-cutting on one machine, a computerized carton printing machine like the K4 from MECVORA brings the whole flow under control. K4 is a semi-automatic flexo printer slotter die cutter that combines the flexographic printing unit, the slotting section and rotary die-cutting in a single pass. The corrugated sheet enters the feeder and leaves as a blank ready to fold and glue, with no transfers between several machines.
Built on a rugged frame with hardened and ground gears (over 60 HRC) and chromed rollers, this carton printing machine is designed for series production across two and three shifts. It slots naturally into a corrugated conversion line and covers formats from 900×2000 up to 1600×3200 mm. Explore the rest of the MECVORA corrugated carton machinery range to complete your line.
Benefits of a carton printing machine with flexo printing slotting
A well-chosen carton printing machine changes the economics of a packaging plant: it removes transfers between machines, cuts handling and brings flexo printing slotting under your control. Instead of sending boxes out to be printed, you make everything in-house at a predictable cost per box. Here are the concrete benefits you look for in the K4 model:
• Three operations in one pass, flexographic printing, slotting and rotary die-cutting, with no transfers between machines and fewer rejects.
• PLC touch-screen control, order parameters are set and saved on screen, for fast order changeover.
• Order memory, recurring boxes are reloaded from saved recipes, which shortens dead time between runs.
• Stable print register, chromed cylinders and hardened gears hold colour position batch after batch.
• European-standard electronic and pneumatic components, for reliable operation and predictable maintenance.
• Fine gap adjustment, clearances between cylinders and rollers are adjusted and locked, keeping precision over time.
• Durable construction, chromed rollers and cylinders, expansion sets that reduce shaft wear and keep accuracy for years.

Applications and industries for a flexo slotter die cutter
A flexo slotter die cutter like the K4 serves first of all corrugated carton box plants: regular slotted cases, e-commerce boxes, food packaging, appliance boxes and shipping cartons. Wherever boxes are produced in volume, this carton printing machine shortens the path from printed sheet to a blank ready for finishing.
Packaging suppliers for retail and distribution use the machine for custom boxes with logo and product information printed straight onto corrugated board. The equipment meets the requirements applicable to CE-marked industrial machinery, in line with the EU Machinery Regulation 2023/1230. Discuss the right configuration with the UZINEX team.
The growth of online retail has raised demand for custom boxes printed with logo and brand message. This is where a computerized carton printing machine like K4 makes the difference: consistent flexo printing slotting straight from corrugated board, with no labels applied afterwards. For plants serving several clients with different artwork, order memory on K4 shortens dead time between runs and keeps the machine productive all day.
Flat-pack furniture makers, automotive spare-part suppliers and agricultural producers use the same flexo slotter die cutter for transport boxes sized exactly to the product. An in-house corrugated box machine gives you control over lead times and over cost per box, a concrete advantage when volumes grow and orders become repetitive.
Logistics operators and online marketplaces increasingly order boxes sized to specific shipments to reduce void space and shipping cost. A manufacturer with its own corrugated box machine can switch size and print from one client to another quickly, without tying up the line and without waiting on an outside printer. It also lets you answer a rush order the same day, instead of queuing behind a subcontractor's schedule.
Compatible materials
This carton printing machine processes the main types of corrugated board, with a maximum sheet thickness between 8 and 12 mm depending on format. The flute types below are indicative and are confirmed according to the machine configuration.
| Material | Notes |
|---|---|
| Single-wall corrugated (B, C, E flute) | common for retail and shipping boxes |
| Double-wall corrugated (BC, EB) | for heavy-duty transport packaging |
| Micro-flute (E, F) | for presentation boxes with fine print |
How it works
The workflow on this carton printing machine is simple and repeatable, from carton sheet to finished blank:
1. The operator loads the stack of corrugated sheets onto the feeder and sets the format on the touch screen.
2. They select a saved order or enter the parameters: number of colours, slotting and die-cutting dimensions.
3. Sheets pass through the flexographic printing unit, with register held by the chromed cylinders.
4. The slotting section makes the slots and creases for folding, at the set depth.
5. Rotary die-cutting produces the box contour and the final cut-outs.
6. Blanks exit stacked, ready for folding, gluing or stitching.
Because the PLC system saves orders, repeating a recurring run needs only a few taps on the screen, and a new operator reaches consistent results quickly. The whole cycle, from loading to the first good boxes, takes minutes, not hours, and production is planned around your deadlines, not around a subcontractor's availability.
Expansion sets and hardened gears keep accuracy after thousands of operating hours, while lockable gap adjustments reduce wear over time. In practice, this means fewer unplanned stops and print quality that stays consistent over the machine's life, a key point for plants running several shifts.
Frequently asked questions
What exactly does this carton printing machine do?
It combines three operations in a single pass: flexographic printing of the corrugated sheet, slotting (the slots and creases for folding) and rotary die-cutting of the box contour. The result is a blank ready to fold, glue or stitch, with no transfers between separate machines.
What speed does the K4 model reach?
Printing speed is up to 200 m/min, and maximum machine speed is between 180 and 300 pieces per minute, depending on the chosen format. Real values depend on the box type and configuration; we confirm them in the personalised quote.
What formats and board thickness does it accept?
K4 covers formats from 900×2000 up to 1600×3200 mm and a maximum sheet thickness between 8 and 12 mm, depending on size. We confirm the format and compatible flutes according to the profile of your orders.
How does it differ from an inline folder gluer line?
This carton printing machine delivers the flat blank, printed and die-cut, ready to be finished separately. An inline line adds automatic folding and gluing at the end. The semi-automatic solution offers greater flexibility on varied orders; we can discuss the integrated option if volumes justify it.
What does installation and commissioning involve?
Transport, installation, commissioning and operator training are provided by the UZINEX team. Before shipping, the machine goes through a functional test, so your line becomes operational quickly, with no hidden costs.
How quickly can an order be changed on the K4?
Thanks to PLC touch-screen control and order memory, moving from one box to another needs minimal setup. For recurring orders, reloading a saved recipe sharply cuts dead time, which matters most on short and varied runs.
Is the machine suitable for EU co-financed projects?
Yes. It ships with CE-compliant components and the related conformity documentation, which makes it eligible for co-financed investment projects. On request, we provide the certifications and technical sheet needed for the file.
