A professional grey board making line is core automated equipment for manufacturing high-quality grey board and rigid cardboard for packaging, stationery, printing and furniture industries. Our fully automatic paper hardboard production line integrates pulping, forming, multi-layer laminating, drying, cutting and stacking into one integrated system, enabling unmanned continuous production from raw material feeding to finished product output. Tailored for medium and large paperboard factories, this high-performance grey board production line effectively solves the pain points of low output, unstable quality, high energy consumption and heavy labor dependence of traditional equipment, significantly boosting manufacturers’ production efficiency and market competitiveness.
As a professional paperboard machinery manufacturer, we specialize in high-standard grey board making machine line and grey board paper making line that comply with international manufacturing standards. Adopting a modular structure, our automatic grey board making line supports flexible customization of production width, basis weight and lamination layers. It produces 2-6 layer composite grey boards with a basis weight of 80g/㎡ to 1500g/㎡, covering thin packaging grey paperboard and thick rigid grey board for high-end rigid boxes and furniture backing. It adapts perfectly to both small-batch diversified production and large-scale mass production scenarios.
Core Advantages of Our Grey Board Making Line
1. Full Automatic Intelligent Control, Low Labor Cost
Our fully automatic grey board making line is equipped with a precision PLC intelligent control system for one-click start-stop, automatic parameter adjustment and real-time production monitoring. Operators can preset speed, board thickness, temperature and cutting dimensions via the touchscreen, with the system automatically correcting operational deviations for consistent product specifications. The entire process from pulping, web forming, hot-press lamination and constant-temperature drying to cutting and stacking requires minimal manual operation, cutting labor costs by over 60%. This smart grey board production line also supports remote operation and fault self-diagnosis, reducing maintenance difficulty and production downtime.
2. Energy-Saving & Eco-Friendly, Low Production Cost
This energy-saving grey board paper making line uses 100% recycled waste paper and cardboard as raw materials, lowering procurement costs while meeting global green production standards. Equipped with circulating hot air drying systems and frequency conversion motors, it reduces power and heat loss, achieving 20%-30% lower energy consumption than conventional equipment. The matched pulping system features high-efficiency impurity removal and circulating water purification, realizing zero wastewater discharge and dust-free operation. It is an ideal eco-friendly automatic paper hardboard production line for modern sustainable paper factories. 3. Stable Operation & Superior Finished Product Quality
Our industrial grey board making line adopts a thickened anti-corrosion frame and high-precision transmission parts, ensuring stable long-term operation and low failure rates. The optimized long-mesh and round-mesh combined forming technology ensures uniform fiber distribution, while constant-temperature hot pressing delivers flat, compact, delamination-free grey boards with high hardness, good toughness and neat edges. The finished products fully meet quality standards for high-end packaging, book covers, rigid boxes and furniture lining. Running stably at 18-70m/min, the equipment maintains a ultra-low defective rate for consistent high-quality output.
4. Flexible Customization & Wide Application Range
Our customizable grey board making line supports personalized configuration of production width (1600mm-3400mm), basis weight and lamination layers, producing single-layer, multi-layer composite and thick rigid grey boards for diverse needs. The finished products are widely applied in carton packaging, gift boxes, stationery, paper tubes and furniture packaging. Featuring a compact and reasonable layout, the line saves factory space and is easy to install, commission and maintain, suitable for new factory construction and old production line upgrades.
Complete Production Process of Grey Board Making Line
The full-set grey board making line supports a complete closed-loop production process. Waste paper raw materials are crushed and pulped, then purified via impurity removal and screening to obtain qualified pulp. The pulp is formed into uniform paper web, laminated into multi-layer boards, and processed through constant-temperature drying, hot pressing, fixed-length cutting, edge trimming and automatic stacking. The fully linked automated process eliminates manual intermediate handling, delivering far higher efficiency than traditional standalone equipment production modes.
