Shipping Cartons for Transport, Warehousing and Distribution
The Corrugated Cardboard Production Line is a continuous, automated system engineered to convert containerboard rolls into single-wall (3-layer), double-wall (5-layer), or triple-wall (7-layer) corrugated boards. Designed for high-volume box plants, the system integrates roll handling, preheating, fluting, gluing, single-facing, bridging, double-backing, slitting-scoring, and cut-off operations into a synchronized manufacturing workflow.
Manufacturing Capability Snapshot
• In-House Machining: Heavy structural components (such as suction boxes, corrugated rolls, and pressure rolls) are processed on large-scale CNC floor boring and milling machines to guarantee structural rigidity and concentricity.
• Dynamic Balancing: All high-speed rotating rolls undergo strict dynamic balancing at operational speeds exceeding 3000 RPM to minimize mechanical vibration and radial runout.
• Surface Treatment: Corrugated rolls are manufactured from 48CrMo alloy steel, induction-hardened, and plated with functional hard chro

Key Features & Technical Logic
Hydraulic Mill Roll Stand:
Shaftless hydraulic clamping and arm lifting handle rolls up to 3 tons per side, reducing roll loading time to under 45 seconds.
01
Negative Pressure Single Facer:
Air suction stabilizes the medium on the corrugating roll, enabling high-speed flute formation without collapse or distortion.
02
Precise Glue Application:
Anilox roller gap adjustment utilizes pneumatic-mechanical linkage, maintaining glue film thickness within ±0.005 mm across variable speeds.
03
Thin-Blade Slitter Scorer:
Tungsten alloy steel blades achieve automatic sharpening and motor-driven lateral positioning in under 3 seconds without stopping production.
04
Helical Cut-Off Knife:
Spiral shear geometry reduces mechanical load on the drive motor, yielding clean, edge-crush-free cross cuts at high speeds.
05
E-Commerce Mailing Boxes: Produces high-strength B-flute and E-flute boards optimized for lightweight, crush-resistant shipping containers.
Industrial Heavy-Duty Packaging: Manufactures heavy 5-layer (BC flute) and 7-layer (AAA/BBC flute) corrugated sheets for machinery, automotive spare parts, and bulk agricultural produce.
Retail-Ready Packaging (RRP): Delivers clean slotting and high-precision creasing for corrugated trays and shelf-ready displays requiring structural fold accuracy.
Modular Configuration
The production line is modular, allowing configuration based on factory floor dimensions, raw material characteristics (kraft liner vs. recycled testliner), and energy availability.
Module 1 (Wet End):
Mill Roll Stands, Preheaters, Single Facers, Bridge Conveyor, Preconditioners, Double Backer.
Module 2 (Dry End):
Rotary Slitter Scorer, Direct-Drive High-Speed Cut-Off, Stacker.
Module 3 (Glue Kitchen & Utilities):
Automatic starch preparation system, steam piping manifolds, and closed-loop condensate recovery units.
Customization Options:
Energy-saving frequency conversion steam heating systems, inline waste trim removal blowers, and remote IoT diagnostic modules.
Reliable corrugated board output depends on strict dimensional tolerance control during manufacturing and assembly.
Raw Material Verification: Ultrasonic testing of structural steel profiles and spectral analysis of alloy steel forgings prior to machining.
Assembly Inspection: Laser interferometer calibration is applied to guide rails and roll parallelism, holding alignment tolerances within 0.05 mm per 3 meters.
Factory Acceptance Testing (FAT): Every line undergoes a 72-hour dry-run simulation test at rated mechanical speeds, verifying electrical synchronization, pneumatic response times, and thermal distribution across heating plates.
Compliance Standards: Built in accordance with CE safety directives and ISO 9001 quality management standards.
