The HX Series is a fully computerized flexo printer slotter die cutter with a full vacuum transfer system and bottom printing, designed for corrugated board packaging manufacturers that need high-fidelity HD printing, with in-line slotting and die-cutting operations, and no organic solvent emissions. The machine uses exclusively water-based ink — a key difference from conventional solvent-ink systems — which eliminates health risks for operators and reduces the cost of complying with environmental regulations.
This flexo printer slotter die cutter is conceived as a direct replacement for offset presses in corrugated board packaging, integrating in-line vacuum pre-feeding, HD printing, varnishing, drying, computerized slotting and rotary die-cutting. The bottom printing structure with vacuum ensures that the printed image is not contaminated during processing and significantly simplifies cleaning of the die-cutting table.
Key advantages of the HX Series flexo printer slotter die cutter
• Water-based ink — no organic solvents – unlike conventional flexo systems with solvent ink, the HX Series flexo printer slotter die cutter uses water-based ink that produces no toxic fumes, protecting operator health and eliminating the need for special ventilation or additional environmental permits.

The difference between the HX Series and the HS Series — how to choose the right flexo printer slotter die cutter
Both series are flexo printer slotter die cutters with full vacuum, but with different orientations. The HX Series uses bottom vacuum printing and water-based ink — the main advantage being that the printed image is not contaminated during processing, while the absence of organic solvents eliminates occupational health and environmental compliance issues. It is the recommended choice for manufacturers that process large formats (up to 1540×3280 mm in the 1630X model) and have strict requirements regarding workplace environment quality or ecological certifications for the finished product.
The HS Series uses top vacuum printing and reaches higher speeds (up to 250 pcs/min versus 180 pcs/min for the HX). If maximum productivity on medium formats is the main priority, the HS Series is the optimal choice. If large format, water-based ink and protection of the printed image are decisive, the HX Series flexo printer slotter die cutter offers the right advantages. UZINEX provides free technical consultancy to select the correct configuration based on your specific production flow.
Applications and industries for the HX Series flexo printer slotter die cutter
The HX Series flexo printer slotter die cutter is intended for corrugated board packaging plants that produce printed boxes for the food, beverage, cosmetics and household appliance industries, and any sector where graphic quality and ecological compliance are simultaneous requirements. The use of water-based ink makes it particularly suitable for packaging in indirect contact with food, where European regulations impose severe restrictions on the migration of substances from the ink.
Manufacturers of furniture, equipment and industrial components that need large-format boxes — up to 1600×3280 mm die-cutting in the 1630X model — will find in the HX Series one of the few flexo printer slotter die cutters available on the Romanian market capable of processing such dimensions in a continuous flow, with integrated HD printing.
Companies with environmental certifications (ISO 14001, FSC, eco-friendly packaging) or that supply markets with strict VOC (volatile organic compound) regulations benefit directly from the water-based ink system of the HX Series flexo printer slotter die cutter, without additional investment in vapor capture systems or special industrial ventilation.
How the HX Series flexo printer slotter die cutter works
1. Vacuum feeding – corrugated board sheets are picked up automatically by the vacuum system and transferred stably along the entire length of the line, without slipping or misalignment, including for warped, thin board or board with variable surface quality.
2. 3-stage dust removal – before printing, the board surface is cleaned electrostatically, blown with 8 rows of rotary brushes and suctioned with an adhesive roller, ensuring optimal adhesion of the water-based ink.
3. Bottom HD flexographic printing – the printing units apply the water-based ink to the bottom surface of the board at 50–133 LPI resolution, with ±0,3 mm accuracy; the doctor-blade system ensures uniform, controlled deposition.
4. Varnishing and drying – the varnishing section applies the finish synchronized with printing; if water-based varnish is used, infrared drying is applied; if UV varnish is used, drying is done by UV, ensuring a hard, smooth and attractive finish.
5. Computerized slotting – the slotting unit with computerized knife-spacing adjustment makes the flutes and creasing lines with ±1,5 mm accuracy; changing the job is done from the touchscreen, with no manual mechanical intervention.
6. Rotary die-cutting – the die-cutting unit cuts out the final box format with ±1 mm accuracy, in a continuous line with all previous operations, without manual transfer of the semi-finished products.
7. Automatic stacking and discharge – the finished boxes are stacked and discharged automatically, ready for gluing, shipping or integration into the next production flow.
Frequently asked questions about the HX Series flexo printer slotter die cutter
Why is water-based ink important compared to solvent ink on a flexo printer slotter die cutter?
Solvent inks contain volatile organic compounds (VOCs) that evaporate into the factory air, exposing operators to fumes harmful to the nervous system and liver. The HX Series flexo printer slotter die cutter uses exclusively water-based ink, completely eliminating this problem. The practical benefits are manifold: no special ventilation or vapor capture systems are required, the plant can more easily obtain ecological certifications, and the packaging can be used in applications with restrictions on the migration of chemical substances from the ink.
What maximum formats can the HX Series flexo printer slotter die cutter process?
The 1628X model processes board formats up to 1540×2880 mm, with die-cutting up to 1600×2880 mm. The 1630X model extends the maximum length to 1540×3280 mm board and 1600×3280 mm die-cutting — one of the largest formats available in an integrated flexo printer slotter die cutter on the Romanian market. Both models process corrugated board thicknesses between 2 and 9 mm.
Can the HX Series machine process low-grade or warped board?
Yes — the bottom vacuum system and the pneumatic air-volume adjustment are specifically designed to ensure stable transport even on warped, unevenly corrugated board or board with surface variations. This is one of the technical differences from conventional chain- or belt-transport systems, which generate register errors on materials with dimensional deviations.
What is the real difference between the HX Series (UZX-188) and the HS Series (UZX-187)?
The HX Series has BOTTOM vacuum printing and uses water-based ink (solvent-free), ideal for ecological certifications and large formats (up to 1540×3280 mm). The HS Series has TOP vacuum printing and reaches higher speeds (250 pcs/min vs 180 pcs/min). The choice: HX if environmental compliance and large format are priorities; HS if maximum productivity on medium formats is decisive.
What corrugated board thickness can the HX Series process?
Both models (1628X and 1630X) process corrugated board with thicknesses between 2 and 9 mm — covering standard single wall, double wall and triple wall structures in the packaging industry. The standard printing plate thickness is 7,2 mm, compatible with common flexo plates on the market.
Is the HX Series machine eligible for EU-funded projects?
Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for EU-funded projects — NRRP, the Regional Program, the Just Transition Program. The HX Series flexo printer slotter die cutter is particularly suitable for funding applications with an ecological component (water-based ink, VOC-free). UZINEX provides all the technical documentation for public procurement procedures and tenders.
What technical connections and utilities does the HX Series require at installation?
The machine requires CE-compliant three-phase electrical supply (Siemens, Schneider, AirTac components), connection to an industrial compressed-air system for the pneumatic systems, and a network connection for the remote monitoring function. The water-based ink eliminates the need for vapor capture systems or special ventilation. The installation space is sized according to the chosen model (1628X or 1630X) — UZINEX provides the technical layout plan, installation and operator training.
