Hardboard production line is a complete industrial production system specially designed for manufacturing high-density, high-strength grey paper board widely used in packaging, printing, stationery, furniture backing, and industrial lining fields. As one of the most cost-effective paper production equipment, the full-automatic grey board making line integrates pulp feeding, forming, pressing, drying, calendering, slitting, and rewinding into one streamlined workflow, realizing continuous, stable, and high-output grey board manufacturing for medium and large paper factories worldwide.
Different from ordinary paper making equipment, our grey board production line is professionally optimized for thick paper board production. It can process waste paper pulp, wood pulp, and mixed pulp raw materials efficiently, producing 1.0mm–6.0mm thick grey board with uniform thickness, flat surface, high stiffness, and excellent compression resistance. The whole grey board making machine line features low energy consumption, low failure rate, and fully automated operation, effectively reducing manual costs and improving production efficiency for paper processing enterprises.
Core Advantages of Our Grey Board Making Line
Our industrial-grade grey board making line adopts advanced papermaking technology and precision mechanical structure, perfectly adapting to mass production demands of different specifications of grey board. Here are the core competitive strengths that make our equipment stand out in the global market:
1. Full Automatic Intelligent OperationThe entire automatic grey board making line is equipped with PLC intelligent control system, realizing one-key start, automatic pulp proportioning, automatic tension adjustment, and automatic fault alarm. Workers only need to set parameters, and the equipment can run stably for 24 hours continuously. It greatly reduces manual operation errors and improves product yield, suitable for large-scale industrial production.
2. High Production Efficiency & Stable OutputThis grey board manufacturing line supports customized production width and speed, with daily output ranging from 5 tons to 50 tons according to different model configurations. The optimized pulp forming and hot pressing process ensures no deformation, no warping, and uniform density of finished grey board. Stable production capacity helps customers shorten delivery cycles and expand market share rapidly.
3. Wide Raw Material Adaptability & Low Production CostThe grey board making line for paper factory can make full use of recycled waste paper, carton scraps, and wood fiber pulp as raw materials, realizing waste recycling and reducing raw material investment costs. Equipped with energy-saving drying and power-saving transmission system, the equipment effectively lowers daily operating power consumption, bringing higher profit margins for production enterprises.
4. Superior Finished Board Quality & Wide ApplicationThe finished products produced by our grey board production machine line have smooth surface, high hardness, good toughness, and excellent folding resistance. The grey board can be widely used in gift box packaging, shoe box backing, notebook cover, furniture base plate, industrial gasket, and other fields, meeting the quality standards of mid-to-high-end packaging and printing industries.
5. Durable Structure & Easy MaintenanceAll key parts of the industrial
automatic paper hardboard production line adopt thickened steel structure and anti-corrosion and wear-resistant accessories, with long service life and stable mechanical performance. The equipment adopts modular design, which is convenient for daily inspection, maintenance, and parts replacement, reducing later operation and maintenance costs and downtime loss.
