Ⅰ.Continuous Flat-Press Hot Pressing Line
1.This is the most advanced and efficient core production equipment in modern panel production (especially for OSB, particleboard, MDF).
Continuous: Refers to an uninterrupted production process where the mat continuously enters the press, and the pressed panel continuously exits. Compared to traditional intermittent multi-opening hot presses (which press batches of panels, requiring opening/closing and loading/unloading), continuous presses have no idle time, offering extremely high efficiency.
Flat-Press: Pressure is applied perpendicular to the panel surface, producing flat panels. This is the most common production method.
Hot Pressing Line: The entire system incorporating heating and pressing functions. Typically consists of an infeed section, the heating/pressing section (core), and an outfeed section.
2.40-Meter Long: This refers to the length of the heating/pressing section (the press itself) being 40 meters. This is a very long specification for continuous panel presses.
Standard OSB lines operate at 20-30m press length. The 40m configuration represents top-tier industrial capacity.
Strategic Advantages:
38.5m effective pressing zone (with entry/exit transitions), ranking in global top 5% for output
Simultaneous pressing of 4 standard OSB panels (1.25m×4m), daily output >2,200m³
Compatible with ultra-thick structural boards (80mm) and thin surface layers (0.8mm)
II. OSB Line Workflow & Key Components
OSB: Oriented Strand Board. An engineered wood panel made by bonding multiple layers of directionally aligned wood strands (flakes) with a thermosetting resin adhesive under high temperature and pressure. Known for its high strength, dimensional stability, and cost-effectiveness, it's widely used in construction (walls, roofs, flooring), packaging, and furniture.
1. Production Process
① Oriented Strand Layup: Cross-layered mat formation (core layer ≥70% cross-direction, surface ≥85% longitudinal)
② High-Pressure Pre-press: Roller compaction at 8MPa eliminates >90% air voids
③ Continuous Hot Pressing:
Steel Belt Drive: Constant 1.8m/min feed (40m traversal in 22 seconds)
Four-Stage Temp. Control:
0-10m: 210℃ rapid PF resin activation
10-25m: 195℃ deep core penetration
25-35m: 185℃ uniform curing
35-40m: 170℃ gradient stabilization
Servo Pressure Profile:
0-5s: 7MPa surface compaction →
5-100s: 4MPa core curing →
100-120s: 2MPa spring-back suppression
④ Water-Cooling: Dual-cycle system reduces panel temp. to <75℃ in 3 seconds
⑤ Flying Cut: Laser-guided saw (±0.3mm accuracy)
2. Core Components
Extended Heated Platens: 40 independently controlled zones (special alloy steel, 350℃ resistant), ΔT≤±2℃
High-Speed Hydraulics: 480 servo cylinders (100mm bore), pressure fluctuation <0.2bar
Intelligent Belt Drive: Dual-motor synchronization, tension deviation <1%
Real-Time QA System:
Millimeter-wave thickness gauge (0.02mm precision)
IR thermal imager (±1.5℃ resolution)
III. 120-Second Curing
120-Second Curing Time: This indicates that the OSB mat (the glued and formed mat before pressing) spends approximately 120 seconds (2 minutes) total within the heating/pressing section of the continuous flat-press, from entering the pressing zone to exiting it.
Curing: Refers to the chemical reaction (cross-linking) of the thermosetting resin (typically MDI or phenolic resin) under high temperature and pressure, firmly bonding the wood strands together and forming the final strength of the panel. This time is crucial for the panel's physical and mechanical properties (e.g., internal bond strength, modulus of rupture, modulus of elasticity, thickness swelling).
Significance of 120 Seconds: This is a relatively short curing time, especially for structural panels like OSB which typically require longer curing times compared to MDF/particleboard. It reflects the high efficiency of this production line and optimized processes (e.g., use of high-performance resins, precise temperature and pressure control).
Industry Comparison:
Panel Type | Conventional Curing | Our Technology | Efficiency Gain |
18mm OSB | 180-240s | 120s | ≥33% |
28mm Structural | 360-480s | 210s | ≥42% |
Technical Innovations:
HF Electromagnetic Heating: Core layer heating rate 15℃/s (vs. 5℃/s steam heating)
Nano-Enhanced Resin: Modified PF resin reactivity +40%
Dynamic Pressure Compensation: Real-time offset of thermal expansion
Quality Metrics:
Internal Bond ≥0.48MPa (EN300)
Thickness Tolerance ±0.15mm (18mm panel)
Formaldehyde Emission ≤0.025mg/m³ (CARB P2)
Ⅳ.Core Advantages of "40-Meter Length + 120-Second Curing"
1. Ultra-High Production Capacity: A 40-meter length combined with a 120-second curing time enables an extremely high production line speed. Curing Time (T) = Press Length (L) / Line Speed (V). Therefore, V = L / T = 40m / 120s ≈ 0.333 m/s. Assuming a finished panel width of 2.5 meters, the theoretical hourly output is: 0.333 m/s * 2.5m * 3600 s/h ≈ 3000 m²/h. Considering practical efficiency (e.g., belt changes, maintenance), the annual capacity can reach 300,000 - 500,000 m³ or even higher. This makes it ideal for large-scale OSB plants.
2. Capability for Thick Panel Production: Producing thick panels (e.g., 25mm, 30mm, or thicker) requires longer curing times to ensure full resin curing in the core. The 40-meter length provides sufficient space, allowing safe and effective production of high-quality thick panels within 120 seconds or slightly longer, without excessively sacrificing speed.
3. Optimized Curing Process: The 40-meter length allows for more process control zones. This enables engineers to design finer, more tailored process curves (temperature profile, pressure profile, closing speed profile) that closely match the resin curing reaction requirements (e.g., different needs at different stages), resulting in:
3.1 Higher Quality Panels: More uniform density distribution, better internal bond strength, lower thickness swelling, more stable dimensions.
3.2 Shorter Curing Times: Precise control (e.g., rapid heating at the inlet, high pressure promoting heat transfer) allows achieving the relatively short 120-second curing time while ensuring quality.
3.3 Adaptability to Different Raw Materials/Formulations: Greater flexibility to adjust the process for different wood species, strand moisture contents, or resin formulations.
4. Energy Saving & Reduced Consumption:
4.1 Continuous Production: Eliminates the energy consumption associated with opening/closing and loading/unloading of batch presses.
4.2 Efficient Heat Transfer: The steel belt system in continuous presses generally has higher heat transfer efficiency than the platens of multi-opening presses.
4.3 Precise Control: Zone control prevents excessive heating/pressing, reducing wasted energy.
5. High Automation & Stability: Continuous flat-press lines are highly automated, with precise and stable control of process parameters (temperature, pressure, speed), minimizing human influence and ensuring consistent product quality.
6. Reduced Unit Cost: Ultra-high capacity spreads fixed costs (equipment depreciation, energy, labor), improving economic efficiency.
