Industrial Flexographic Printing Machine & CI Flexo Press Line
Engineered to resolve web stretching, register wander, and ink misting across extensible substrates, OYANG's industrial flexographic printing machine series delivers synchronized continuous reel-to-reel converting up to 250 m/min. Featuring our flagship ci flexo printing machine (Central Impression) architecture anchored by a precision-machined central drum (≤ 0.008 mm dynamic runout) and ceramic anilox metering, our presses maintain a color registration accuracy of ≤ ±0.10 mm across thin PE film, flexible barrier laminates, kraft paper, and spunbond nonwoven fabrics.
Eliminating Web Stretch & Color Shift Across Elastic Substrates
Converting flexible PE film or lightweight spunbond nonwoven fabrics through multi-station printing presents severe color registration errors due to elastic elongation under dynamic web tension. Converting facilities require precision anilox transfer, controlled infrared/hot-air impingement, and thermal drum stabilization to maintain repeat accuracy.
Structural Machine Alignment & Central Drum Stability
OYANG manufactures three specialized flexographic configurations: economical stack flexo (YTB) for rigid paper, central impression (CI) flexo (YTC) with a constant-temperature CI drum to anchor extensible films at 250 m/min, and heavy-duty unit-type inline flexo (FE) for high-tonnage carton pre-printing. All frames are CNC-machined to ensure total mechanical parallelism.
Central Impression (CI) Drum Dynamic Stability & Thermal Balance Matrix
In a ci flexo printing machine, web elongation and pitch distortion are completely arrested by locking the substrate against a single central impression drum. Rather than relying on theoretical friction models, OYANG guarantees color registration stability through measurable mechanical tolerances verified on Japanese MAZAK & OKUMA CNC lines:
| Critical Subsystem | Engineering Tolerance / Spec | Production Performance Impact |
|---|---|---|
| Central Impression Drum | ≤ 0.008 mm radial dynamic runout | Eliminates dot gain variations across all color stations during 250 m/min continuous runs. |
| Drum Thermal Stabilization | 22°C ± 0.5°C closed water circulation | Restricts film thermal expansion to < 0.02 mm across thin 20μm PE/BOPP, preventing inter-color misregister. |
| Ceramic Anilox & Chamber | 200–1,000 LPI laser engraved + closed blade | Maintains micro-metric ink film thickness; curtails volatile solvent evaporation and ink splashing. |
| Infeed Closed-Loop Tension | ≤ ±0.2 kgf low-inertia dancer control | Prevents web wrinkles and necking on lightweight spunbond nonwovens (30–100 g/m²) during acceleration. |
By wrapping the substrate past a > 270° arc on the chilled drum surface, relative slip between successive printing decks is mechanically impossible, providing absolute register locking without relying on continuous web stretching.
