Post-Press Machine & Industrial Converting Machines Line
Engineered to eliminate inter-process logistics bottlenecks, delamination risks, and die-cutting registration errors, OYANG's integrated post press machine lines synchronize the entire downstream workflow from raw printed web to finished carton. Functioning as cohesive industrial converting machines, our portfolio integrates high-velocity solvent-free roll lamination (up to 500 m/min), high-speed flute laminating (13,000 sheets/hr), and heavy-duty flatbed die cutting with precision hot foil stamping (up to 600 Ton hydraulic load, ±0.075 mm registration) to deliver rigid luxury boxes, food-barrier pouches, and corrugated cartons from a single engineering baseline.
Three Post-Press Solutions, One Complete Production Chain
OYANG post-press machines cover every manufacturing process from roll barrier film lamination to high-speed board laminating and high-tonnage flatbed die cutting.
Web Lamination for Flexible Pouches & Nonwoven Bags
Three distinct web converting technologies — Extrusion Coating, Solvent-Free PU, and Solvent Dry Lamination — engineered for high-barrier food packaging, pharmaceutical foils, and ultrasonic nonwoven box bag lines.
High-Speed Sheet Laminating for Corrugated Packaging Boxes
The WHL series bonds pre-printed surface paper onto corrugated board or solid cardboard at up to 13,000 sheets/hr with ±1 mm registration accuracy. Supports card-to-card and card-to-flute converting without mechanical retooling. Integrated Profinet port for MES connectivity.
Industrial Flatbed Die Cutting & Stamping Systems
Four specialized series covering standard die cutting, heavy hydraulic embossing, hot foil stamping, and dual-station single-pass converting — handling sheet widths from 1050 mm up to 1650 mm across solid paperboard and corrugated flutes.
Engineering Benchmark: Lamination vs Flute Laminator vs Flatbed Die Cutter
Cross-evaluate converting functions, web versus sheet formats, speed ceilings, and registration tolerances to match factory specifications.

Full-Chain Converting Machine Topology
From raw substrate lamination upstream to precision inline die cutting and stripping downstream, OYANG post-press lines eliminate third-party logistics and material bottlenecking.
Industries & Converted Packaging Structures
OYANG post-press machines serve packaging converters, commercial carton plants, and brand packaging converters worldwide.
Platen Tonnage Dynamics & Structural Deflection Matrix
In high-tonnage converting machines, insufficient structural mass causes platen micro-flexing, resulting in incomplete knife penetration on dense corrugated flutes and creasing bursts on coated cartonboard. OYANG eliminates toggle linkage deflection through verified manufacturing standards machined across in-house Japanese MAZAK five-axis centers:
| Converting Subsystem | Engineering Tolerance / Material Spec | Downstream Quality Guarantee |
|---|---|---|
| Platen Casting Integrity | QT600-3 High-Strength Nodular Iron | Prevents frame fatigue under 600-ton shock loads, ensuring zero platen deformation during continuous 8,500 sh/hr cycles. |
| MAZAK Platen Surface Flatness | ≤ 0.015 mm overall bed planarity | Guarantees uniform cutting depth across sheet widths up to 1,650 mm, eliminating manual knife underlay patching. |
| Dynamic Gripper Positioning | ±0.075 mm optical registration accuracy | Locks foil-to-cut registration on luxury liquor cartons and pharmaceutical folding boxes without edge drift. |
| Solvent-Free Metering Stability | 0.8–2.5 g/m² precision adhesive coating | Maintains optical transparency and bond strength on high-barrier retort pouches at line velocities up to 500 m/min. |
By combining heavy-gauge box-type toggle frames with stress-relief heat treatment, OYANG converting lines maintain micro-metric parallel contact across 24-hour manufacturing shifts, completely eliminating cutting burrs and matrix creasing collapse.
