The Lightweight High-Strength Board Continuous Flat-Press Production Line (Density ≤650kg/m³) is a revolutionary panel production equipment designed to manufacture innovative boards with a density not exceeding 650kg/m³ while possessing exceptional mechanical properties. Conventional wisdom suggests that lightweighting panels often comes at the expense of strength. This production line successfully breaks this limitation through a series of cutting-edge technologies and precise processes, providing core assurance for clients to produce high-value-added, lightweight panels that align with modern energy-saving and environmental trends.
Core Advantages and Value
1. Breakthrough Performance Ratio: The core achievement lies in realizing "low density, high strength." The produced boards are over 20%-30% lighter than standard Medium-Density Fiberboard (MDF), yet key indicators like Modulus of Rupture (MOR) and Internal Bond (IB) strength meet or even exceed standard requirements.
2. Excellent Energy Saving and Environmental Friendliness:
Raw Material Savings: Consumes less wood raw material for the same volume, directly reducing material costs.
Reduced Energy Consumption: Lighter boards require less thermal and mechanical energy during hot pressing. The production line itself also features an energy-efficient design.
Green Product: Lighter finished boards mean lower carbon emissions during transportation, complying with green supply chain requirements.
3. Superior Board Functionality: The low-density structure grants the boards excellent thermal insulation and sound absorption properties, making them ideal for applications with dual requirements for weight and performance, such as interior partitions, door cores, and feature walls.
4. High Production Efficiency and Automation: Based on continuous flat-press technology, it enables uninterrupted continuous production, featuring high automation, stable operation, large output, and low labor costs.
Core Design Features: Optimized for Lightweight Boards
1. Gap Control Mode: Unlike the primary use of "pressure control" for producing high-density boards, this flat-press emphasizes gap control. The system precisely sets and maintains a fixed opening between the upper and lower hot plates, which directly determines the final thickness and density of the board. This allows the mat to be moderately compressed and cured while maintaining its fluffy structure.
2. Reduced Pressing Force: The maximum pressing force provided by the hydraulic system is optimized—sufficient to create effective bonding between fibers but avoiding over-compaction that would increase density.
3. Zoned Fine-Pressure Adjustment: The press is divided into multiple independent pressure zones along its length. The pressure in each zone can be independently and precisely adjusted. For instance, lower pressure is applied at the inlet zone for pre-curing to prevent over-compaction of the fluffy mat; optimal pressure is applied in the main curing zone to achieve strength; and pressure is reduced again at the outlet zone to stabilize the structure.
4. Precise Temperature Profile Control: The hot plates are also divided into multiple independent temperature control zones. By setting different temperatures for different sections (e.g., lower at the inlet to prevent premature adhesive curing, higher in the main zone to promote rapid curing), an optimal temperature profile is created, ensuring the adhesive cures uniformly and thoroughly between the fibers of the porous structure.
Main Components
1. Frame: A robust steel structure that provides stable support for the entire press, withstands the immense reaction forces generated during pressing.
2. Hot Plate System:
Material and Machining: Made from high-strength alloy steel, precision-machined to ensure surface flatness and stability under high temperatures.
Heating Channels: Complex channels are drilled inside for circulating high-temperature thermal oil or steam, providing uniform heat.
3. Steel Belt System:
Function: Two endless loop alloy steel belts run tightly against the upper and lower hot plates, respectively. They carry the mat and pull it at a constant speed through the entire press length, simultaneously transferring heat to the mat.
Requirements: Possess extremely high surface finish, heat resistance, fatigue strength, and dimensional stability.
4. Hydraulic System:
Composition: Includes hydraulic power units, cylinders, servo valves, and accumulators.
Key Capability: Capable of providing extremely smooth, precisely adjustable pressure, with fast, independent response for each pressure zone.
5. Lubrication and Tensioning System: Automatically injects a film of high-temperature lubricant between the steel belts and the hot plates to reduce friction and wear. Simultaneously, tensioning devices ensure the belts maintain proper tension for smooth operation.
6. Infeed and Outfeed Devices: Seamlessly connect to the forming station and the finishing line, ensuring smooth entry of the mat and stable discharge of the finished board.
Brief Working Principle Description
The formed, fluffy mat is fed by the infeed device between the continuously running steel belts. The mat is then drawn into the pressing gap formed by the upper and lower hot plates. While passing through the press, it undergoes:
Preheating and Initial Compression: In the inlet zone, the mat is heated and lightly compressed, achieving initial shape stability.
Main Curing: In the central main sections, under the set gap and optimal temperature and pressure, the adhesive undergoes full curing, forming a strong fiber-adhesive network.
Setting and Cooling: In the outlet area, pressure is gradually released, the board structure is essentially set, and preliminary cooling begins.
Throughout this process, precise gap control ensures consistent density, while zoned temperature and pressure control guarantee the highest possible strength even at low density.
Key Role in Achieving Low Density and High Strength
This dedicated flat-press is the final forming equipment where lightweight potential created in previous steps (like fiber preparation, blending, and fluffy forming) is fixed and reinforced through a controlled thermodynamic process. Its control accuracy directly determines the finished board's density uniformity, thickness tolerance, surface quality, and mechanical strength. It is the "heart" and the primary source of value in the entire production line.
