HUAYU-A Series Corrugated Board Roll Printing, Slotting and Die-Cutting Machine

The HUAYU-A Series is a fully computerized, high-speed corrugated board roll printing, slotting and die-cutting machine, available in 8 configurations, from the 920 model up to the 1632, covering formats from 260×560 mm up to 1540×3350 mm and board thicknesses up to 11 mm. Unlike flexo vacuum systems, this corrugated board roll printing, slotting and die-cutting machine uses direct roll printing and a mechanical transmission with 20CrMnTi alloy-steel gears with level-6 precision, offering maximum mechanical robustness and simplified maintenance for continuous industrial production.

The HUAYU-A Series integrates in-line printing, slotting and die-cutting of corrugated board with thicknesses up to 11 mm, 2 mm more than the HS and HX series, covering a wider range of double-fluted board and more rigid materials used in heavy industrial packaging. The range of 8 models, the skip-feeding function and the individual pneumatic brakes on each part for exact resetting of the gearing phase are distinct technical features compared with any other series in the UZINEX portfolio.

Key advantages of the HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine

• Roll printing: direct visual observation of the printing surface. The roll printing system allows the printing surface to be observed visually in real time, with a simple structure and convenient adjustment, unlike vacuum systems where the printing surface is covered during processing.

• Board thickness up to 11 mm: the largest in the family. The HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine processes corrugated board with thicknesses from 2 to 11 mm, covering triple wall board and rigid industrial materials that exceed the 9 mm limit of the HS and HX series.

• 8 models: the widest range in the UZINEX portfolio. From the 920 (860×2150 mm max format, 260 pcs/min) to the 1632 (1540×3350 mm max format, 120 pcs/min), the HUAYU-A Series covers any industrial corrugated board packaging format, including extra-large formats for furniture, construction and industrial equipment.

• Skip feeding function for formats up to 1900×3350 mm: the skip feeding function extends the maximum processable format significantly compared with standard continuous feeding, allowing the production of very large boxes from a single board sheet without joints.

• Individual pneumatic brakes on each part: each major component of the corrugated board roll printing, slotting and die-cutting machine is equipped with its own pneumatic brakes that ensure exact resetting of the main gearing-point phase after the equipment is separated, eliminating synchronization errors on restart.

• Gear transmission with automatic lubrication pump: the lubrication system with a pump and automatic balancing of the gearbox oil level maintain the same oil level at all gearing points throughout operation, with no manual intervention for lubrication.

• 20CrMnTi alloy-steel gears with level-6 precision: heat treatment and grinding to level-6 precision (a superior industrial standard), with shafts connected through expansion sleeves for precise, backlash-free transmission at high speeds.

• PLC touchscreen control with automatic plate-clear memory: after running the intermediate cleaning stamp, the memory resets automatically without re-printing the plate; the startup protection prevents incorrect operation if the host is not fully powered on.

The HUAYU-A Series versus the HS and HX series: when to choose roll printing

The HS and HX series use flexographic vacuum printing and water-based or solvent ink, with ±0,3 mm printing accuracy and HD resolution of 50–133 LPI, suitable for packaging with high graphic requirements and images of a quality comparable to offset. The HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine uses direct roll printing with ±0,5 mm accuracy, suitable for functional markings, text, codes and simple graphics on industrial packaging where HD resolution is not a requirement.

The decisive advantages of the HUAYU-A Series over the vacuum series are: the maximum board thickness of 11 mm (versus 9 mm), the range of 8 models with formats up to 1900×3350 mm skip feeding, the superior mechanical robustness of the automatically lubricated gear transmission, and simpler maintenance with no vacuum systems. UZINEX provides free consultancy for choosing between roll printing and flexo printing based on the customer's specific requirements.

Applications and industries for the HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine

The HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine is intended for industrial packaging plants that process thick corrugated board (triple wall, 10–11 mm) and need extra-large formats, mechanical robustness and continuous production at industrial capacity. Manufacturers of packaging for furniture, household appliances, industrial equipment, construction materials and heavy technical parts are the main users of this series.

Plants that produce packaging with functional markings (text, logistics codes, simple logo, shipping information) use the HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine because the roll printing system is simpler to adjust and maintain than flexo systems for this category of graphic requirements. The board thickness of up to 11 mm makes it the only machine in the UZINEX family capable of processing triple wall corrugated board in a complete printing and die-cutting flow.

Companies that export bulky products and need extra-large shipping boxes (up to 1900×3350 mm with the skip feeding function) find in the 1628 and 1632 models of the corrugated board roll printing, slotting and die-cutting machine the only solutions available in Romania for these dimensions in a complete automated flow.

How the HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine works

1. Edge-guide feeding with electronic stroke adjustment: the guide edge electronically adjusts the feed stroke and reduces the paper roller pressure, ensuring correct board entry regardless of thickness (2–11 mm) and format.

2. Startup protection and synchronization check: the startup protection system verifies that all host components are active before allowing the machine to start, preventing incorrect operation and mechanical damage.

3. Direct roll printing: the printing roller applies the ink to the board surface with ±0,5 mm accuracy; the printing surface is directly visible during production, allowing real-time quality checking without stopping the line.

4. Automatic plate-memory clearing: after running the intermediate cleaning stamp, the PLC memory resets automatically; when production restarts, the plate does not need to be re-printed, saving time and material.

5. Computerized slotting with pneumatic brakes: the slotting unit makes the flutes and creasing lines with automatic adjustment of the knife spacing; the individual pneumatic brakes ensure exact resetting of the gearing phase at each restart.

6. Die-cutting with level-6 alloy-steel transmission: the die cutter cuts out the final box format through the automatically lubricated 20CrMnTi gear transmission, with continuous balancing of the oil level at all gearing points.

7. Skip feeding for extra-large formats: the skip feeding function allows the processing of formats that exceed the standard continuous size, extending the machine's capacity to 1900×3350 mm on the 1628 and 1632 models.

Frequently asked questions about the HUAYU-A Series corrugated board roll printing, slotting and die-cutting machine

What is the skip feeding function and when is it useful?

Skip feeding is an intermittent feeding function that allows the processing of board sheets longer than the length of the printing cylinder, by advancing the sheet in successive steps with repositioning between steps. The HUAYU-A Series machine uses skip feeding to process formats up to 1900×3350 mm, significantly larger than the continuous-feed maximum of 1540×3350 mm. It is useful for furniture packaging, large industrial equipment or products that require extra-long boxes from a single board sheet without joints.

Why does the HUAYU-A Series have ±0,5 mm accuracy versus ±0,3 mm on the HS and HX series?

The ±0,5 mm accuracy of the HUAYU-A Series reflects the difference in printing technology: direct roll printing versus flexographic vacuum printing with independent servomotors. For industrial packaging with functional markings (text, codes, simple logo), ±0,5 mm accuracy is more than sufficient. If the graphic requirements include photographic images, gradients or complex motifs at HD resolution, the HS and HX series with ±0,3 mm accuracy and 50–133 LPI resolution are the recommended solutions.

Can the HUAYU-A Series process triple wall board (7 layers)?

Yes. The maximum thickness of 11 mm of the HUAYU-A Series covers standard triple wall corrugated board (CO7), which has typical thicknesses of 9–11 mm depending on the grammage and flute structure. The 920 and 924 models process up to 10 mm, and the models from the 1224 upward process up to 11 mm. UZINEX verifies compatibility with the exact specifications of the customer's board during the free technical consultancy.

How do I choose among the 8 models of the HUAYU-A Series?

The choice depends on format and volume. For high speeds on medium formats (up to 860×2550 mm): 920 or 924, 210–260 pcs/min. For medium-large formats (1160×2950 mm) at speeds of 180–220 pcs/min: 1224 or 1226. For industrial packaging (1370×2950 mm): 1424 or 1428. For extra-large formats (1540×3350 mm continuous, 1900×3350 mm skip feeding): 1628 or 1632 at 120–140 pcs/min. UZINEX evaluates the volume, typical formats and board thickness free of charge to recommend the optimal model.

What is the difference between the HUAYU-A (UZX-195) and the HS Series (UZX-187)?

The HS Series is flexo with full vacuum, ±0,3 mm accuracy, HD resolution 90–133 LPI, board up to 9 mm, up to 250 pcs/min, ideal for packaging with complex graphics (food, cosmetics, FMCG with a color logo). The HUAYU-A is direct roll printing, ±0,5 mm accuracy, board up to 11 mm, up to 260 pcs/min, with 8 models and skip feeding for extra-large formats (1900×3350 mm), ideal for heavy industrial packaging with functional markings (furniture, construction, equipment). Recommendation: HS for maximum graphic quality, HUAYU-A for robustness + large format + thick board.

What does the 20CrMnTi level-6 gear transmission mean?

20CrMnTi is a chromium-manganese-titanium alloy steel used for high-strength gears, with carburizing heat treatment followed by hardening, a combination that produces a very hard surface (wear durability) with a tough core (impact resistance). Level-6 precision (DIN 3961) means a very tight tooth-profile tolerance, under 25 µm: practically no audible gear backlash at industrial speeds. On the HUAYU-A Series, this translates into quiet operation, a long service life (15+ years under normal use) and minimal maintenance; the automatic lubrication pump even eliminates manual greasing.

Is the HUAYU-A 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 HUAYU-A Series is suitable for funding applications with a component for modernizing heavy industrial production lines and automating packaging for strategic sectors (furniture, construction, equipment).
