MINGHUNG
The 280℃ High-Temperature Continuous Flat Pressing Line is revolutionary equipment for the modern wood-based panel industry, developed specifically to meet the demands for high strength, low swelling, and rapid curing in panels like OSB, PB, and MDF. Compared to traditional continuous presses (typically operating at 200-230℃), the core advantage of this equipment lies in its stable operating capability at an ultra-high temperature of 280℃. This makes it particularly suitable for high-end adhesive systems like Phenol-Formaldehyde (PF) or Melamine-Urea-Formaldehyde (MUF) resins, which require high temperatures for rapid and complete curing, enabling the production of top-tier panels for construction structures, humid environments, or high-load-bearing applications.
Ultra-High Temperature Heating & Uniformity Control: Utilizes special alloy heating plates and an optimized high-temperature heat transfer fluid circulation system (e.g., high-temperature thermal oil) to ensure the platen temperature is stably maintained at an extreme level of 280°C ±3°C across the entire press length (tens of meters). This provides a powerful and uniform heat source guaranteeing full resin curing in the panel core.
Multi-Material Compatibility & Flexible Production Design: The press inlet, forming station, and pre-press systems feature modular designs tailored to different raw material characteristics, such as OSB strands, PB coarse particles, and MDF fine fibers. This allows flexible production of various panel types on a single line through parameter adjustments and component changes, maximizing return on investment.
High-Pressure Heavy-Duty Frame & Drive System: To withstand the additional thermal stress from high temperatures and the high specific pressure required for OSB/PB production, the equipment employs a reinforced heavy-duty frame, large-diameter hydraulic cylinders, and a high-torque main drive system, ensuring long-term operational rigidity and stability under demanding conditions.
Precision Thickness Control at High Temperatures: Equipped with high-temperature-resistant thickness sensors (e.g., radiation gauges with special cooling protection) and an adaptive hydraulic gap adjustment system. This enables closed-loop precision control of finished panel thickness, achieving tolerances as tight as ±0.15mm, even accounting for thermal expansion of steel belts and rollers at high temperatures.
Intelligent Control System & Process Database: Integrates an advanced DCS/PLC control system with a built-in proprietary process database for different panels (OSB/PB/MDF) under high-temperature conditions. The system can automatically regulate thousands of parameters, including temperature profiles, pressure profiles, and line speed, enabling "one-click product changeover" and full-process quality traceability.
High-Efficiency Heat Recovery & Utilization: Features an intelligent flue gas heat recovery system and high-temperature zone insulation design. Waste heat from the press is recovered and used for fiber drying or heating systems, significantly reducing the production line's overall energy consumption and aligning with green manufacturing principles.
Main Technical Parameters
Design Maximum Operating Temperature: 280℃ (Adjustable common range: 220-280℃)
Applicable Product Types: OSB, PB, MDF, and their variants (e.g., moisture-resistant, fire-retardant boards)
Finished Panel Thickness Range: 6mm - 40mm (OSB/PB can be thicker)
Finished Panel Density Range: 650 - 750 kg/m³ (PB), 450 ~ 880 kg/m³ (MDF)
Typical Production Line Speed: Up to 1500 mm/s, depending on thickness and resin type
Maximum Specific Pressure: Can be designed per requirement, typically higher than standard MDF presses
Control Accuracy: Thickness control ±0.15mm, Temperature control ±3℃
This 280℃ High-Temperature Continuous Flat Press, specifically designed for PB (Particleboard), OSB (Oriented Strand Board), and MDF (Medium Density Fiberboard), operates on the core principle of utilizing ultra-high temperature and continuous flat-pressing in synergy to achieve efficient, high-performance production of multiple panel types.
Working Principle: Dynamic Hot Pressing and Flexible Production under Ultra-High Temperature
Subjecting different raw materials (strands or fibers) to a continuous, programmable profile of pressure and temperature within a precisely controlled 280℃ ultra-high temperature environment, to activate specific adhesives (e.g., PF/MUF), thereby achieving rapid curing and high-performance forming.
the workflow consists of the following key stages:
1. Flexible Mat Forming and Pre-pressing: This is the prerequisite for producing multiple panel types. The system automatically switches to the corresponding mode based on the production order:
For OSB: An oriented forming head is used to align large strands longitudinally in the surface layers and transversely in the core layer, maximizing the panel's longitudinal mechanical properties, followed by high-pressure pre-pressing to remove air.
For PB: A random forming head is used to distribute particles of varying sizes evenly, creating a stable mat structure.
For MDF: An air-flow forming head is used to ensure fine fibers are distributed uniformly, forming a homogeneous, high-density mat, with relatively lower pre-pressing pressure.
2. Core High-Temperature Continuous Flat-Pressing Process: The mat enters the press formed by two parallel high-temperature steel belts. The core of this process is the "programmable pressing profile." The system automatically executes the optimal combination of temperature and pressure based on panel type and thickness:
High-Temperature Effect (280℃):
Significantly Shortens Curing Time: Especially for resins like Phenol-Formaldehyde (PF), the 280℃ high temperature can increase its curing reaction rate several times compared to conventional 180-220℃ environments, directly boosting production line speed.
Enhances Panel Performance: High temperature ensures complete and deep curing of the resin, greatly improving the panel's internal bond strength, moisture resistance (low thickness swell), and durability, meeting P5/P7 or structural-grade standards.
Optimizes Heat Transfer: A steeper temperature gradient allows heat to transfer to the mat core faster, reducing the curing differential between the core and surface layers.
Continuous Flat-Pressing Process: Clamped by the steel belts, the mat moves forward at a constant speed, undergoing continuous stages of preheating, pressing, high-temperature curing, and pressure-holding setting. Pressure can be finely controlled along a curve from infeed to discharge according to product requirements.
3. Post-Processing and Intelligent Control: The cured panel is cooled, sanded to precise thickness, and sawn into finished dimensions. The entire process is monitored by a Central Intelligent Control System, which integrates dedicated process recipe libraries for PB, OSB, and MDF, enabling "one-click switching" between different products.
