Functions and features
- The wall thickness is 50mm. Internal stress is conditioned using medium-frequency induction heating, increasing the wall's density, hardness, strength, toughness, and conductivity. Artificial aging treatment and pair machining in a large machining center ensure high strength, high precision, and permanent deformation.
- The transmission system uses spur gears throughout, resulting in low noise, increased gear strength, and improved transmission smoothness. All transmission gears are made of high-quality alloy steel, carburized, tempered, and superhardened, then precision ground for high strength and durability.
- All bearings use high-quality NSK and imported Harbin brand bearings, each individually inspected and certified before being stored.
- Each unit has an electric clutch with an alarm bell that continuously sounds when the clutch is engaged or disengaged, ensuring operator safety and buffering collisions between units in case of erroneous operation.
- The machine has an aesthetically pleasing design with soft colors. The modular design allows for easy addition or removal of units.
- A color-coded human-machine interface with touchscreen operation is simple, convenient, and powerful.

Q1: How do you ensure that three-color printing won't be off-center when the machine is running at a high speed of over 180 sheets per minute?
A: We use extra-thick 50mm thick integral wall panels, which are very stable and don't wobble even at high speeds. All transmission gears are made of hardened, wear-resistant alloy steel, equipped with a fully automatic oil-lubrication system, and all core bearings are original Japanese NSK parts. This configuration ensures that even at the highest speed, the three-color printing error will be within $\pm0.5\text{mm}$, absolutely no printing misalignment.

Q2: Will the paper feed be smooth if the cardboard is warped or thin? Will it damage the carton?
A: Absolutely no problem. We use a German-technology leading-edge feeding system equipped with a powerful 7.5kW variable frequency suction fan. If the cardboard is severely warped, you can simply increase the airflow on the screen to flatten it. From thin E-flute mini cartons to heavy 5-ply BC-flute large cartons (2–11mm thick), it can feed smoothly and will absolutely not crush the corrugated structure.

Q3: What are the advantages of an independent servo motor drive for the die-cutting unit?
A: Our die-cutting unit uses an independent servo motor for individual drive. The advantage is that the significant resistance and vibration generated during die-cutting of cartons are completely prevented from being transmitted back to the printing unit, thus preserving the printing quality at the front end. To save you money, the die-cutting pad roller automatically moves left and right during operation for more even wear. The machine also has a built-in electric grinding and repair device, allowing worn pads to be repaired and reused directly on the machine, saving a significant amount on consumable costs.

Q4: What brands of core components does this machine use? Will it be easy to buy spare parts in the future?
A: We use only major international brands for all our machines. No matter which country you are in, you can easily buy spare parts locally, making maintenance extremely convenient.
5
Q5: I've heard that cleaning and wiping printing presses every day is a hassle. Is this machine easy to clean and maintain?
Answer: Extremely worry-free. First, it features a pneumatic automatic lifting anilox roller function. When the machine stops, the roller automatically lifts and starts rotating (driven by the ink distribution motor), preventing the ink from drying and clogging the mesh. Second, each unit has an independent oil pump for closed-loop spray lubrication, which not only reduces gear wear and extends gear life, but also eliminates the need for daily manual oiling of the gears, saving a significant portion of maintenance work.
6
Q6: How does Model 1425 maintain 4-color registration accuracy at its top speed of 250{ pcs/min}$?
A: It utilizes a high-precision vacuum-absorbing feeding system combined with oil-bath lubricated drive gears made of hardened, precision-ground alloy steel (20CrMnTi). Controlled via PLC and a 360-degree motorized phase adjustment system, it strictly limits color registration error to $\le \pm0.5\text{ mm}$ even at maximum velocity, ensuring flawless multi-color overlays for premium packaging.
7
Q7: What are the technical advantages of combining the slotting and die-cutting into a single unit?
A: This consolidated design significantly reduces the machine’s footprint while eliminating the cumulative displacement errors that occur when blanks transfer between separate stations. Synchronized motorized phase adjustment for both the slotting knives and die-cutting cylinders ensures absolute alignment between scores, slots, and complex die-cuts.
8
Q8: How does Model 1425 perform across varying board thicknesses, from micro-flute to heavy duty?
A: With a working size of $1400\text{ mm} \times 2500\text{ mm}$, the machine features motorized, PLC-micro-adjusted gap control. For lightweight flutes (E/F) or heavy 5-layer (BC) boards, the vacuum-absorbent fan utilizes variable frequency drives (VFD) to stabilize warped boards. This prevents flute crushing at $250\text{ pcs/min}$ and fully preserves the board's original structural integrity.
9
Q9: European buyers require rapid job changeovers. What is the actual downtime when switching orders?
A: Model 1425 is built for high-mix, fast-paced production. Its computerized order management system stores hundreds of job profiles. For a standard order change, the setup of slotting heads, panel heights, unit gaps, and print phases automates via a single touch command, completing the entire changeover in just 3 to 5 minutes to maximize uptime.
10
Q10: What is the lifespan of the consumables (anvil covers/knives), and how easy is part replacement?
Die-Cutter: It features a mechanical anvil trimming and automatic speed compensation system. The anvil roll shifts laterally during operation to distribute wear evenly, extending cover life by 2–3 times.
Slotter: Equipped with premium tungsten-alloy knives for exceptional durability.
Global Support: All core electrical components (PLC, inverters, contactors) are sourced from top-tier international brands (Siemens, Schneider, Omron), ensuring hassle-free local parts availability and seamless remote digital diagnostics worldwide.
