In-line flexographic press

8-colorfor plastic filmfor paper

Overview
Adopting full servo control and drive system. The printing unit uses a cantilever beam sleeve structure. Integrated advanced functions include pre-alignment, automatic pressure adjustment, order management and automatic cleaning. CE certified. Suitable for water-based or alcohol-soluble inks and for printing on various papers and films, especially materials prone to stretching or rough-surface paper. Low emissions and environmentally friendly, with potential production cost reduction.

Product Summary
A Customized Flexo Printing Machine from Shaanxi Beiren Printing Machinery Co., Ltd. is engineered for specific substrates, ink systems and production flows. Designed for high registration accuracy and fast changeovers, it combines modular drying systems and flexible web handling to process thin films, rough papers and specialty materials while maximizing overall equipment effectiveness (OEE).

Key Features

• Full Servo Control & Drive System — gearless direct drive enabling infinite print repeat lengths and registration accuracy within ±0.1 mm during acceleration/deceleration.
• Cantilever Beam Sleeve Structure — enables quick changeovers in under 15 minutes by swapping sleeves for print cylinders and anilox rollers.
• Intelligent Automation — pre-alignment, automatic pressure adjustment, order management, HMI job memory and automatic cleaning systems.
• Flexible Ink Compatibility — supports water-based, solvent (alcohol-soluble) and UV/LED-curable inks; modular drying options (hot air, infrared, UV-LED).

Applications
Flexible Packaging for Food & Pharmaceutical
Handles heat-sensitive substrates (e.g., 12-micron PET or BOPP). Integrates chill drums and precise tension control to prevent material damage. Inline solvent retention monitoring aids compliance with food-safety standards.

Corrugated Pre-Print and Post-Print
Equipped with vacuum transfer systems to manage board warping and wide-flute structures while delivering high-graphic multicolor prints comparable to offset at flexo speeds.

Sanitary and Hygiene Products
Wide-web printing on non-woven fabrics with low-tension web paths to preserve softness. Inline embossing units improve ink anchorage without bleed-through. Configurable to exceed 400 m/min when specified accordingly.

Advanced Technical Properties
Modular drying systems are calibrated for substrate thermal sensitivity to prevent deformation. Corrosion-resistant ink circuits are compatible with specified ink chemistries. Advanced tension control uses dancer rolls with pneumatic cylinders and load-cell feedback to avoid neck-in and wrinkles on high-elasticity materials.

Quality Control

• Factory Acceptance Testing (FAT) validates registration stability during speed changes.
• Mechanical stability confirmed by vibration analysis at maximum speeds.
• Drying efficiency validated to match speed and ink volume requirements.
• Tension consistency tested across splicing cycles for zero-speed changeover reliability.
