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.
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.
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.
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.
Different mechanical layouts solve specific converting demands. Match your substrate stretch profile, production speed, and color requirements to the correct press layout.
Economical roll-to-roll printing for paper rolls, woven fabric, heavy foils, and nonwovens. Independent impression rollers per color deck offer unmatched flexibility for double-sided web paths.
