Ⅲ. Core Technologies Enabling High Precision
3.1 Thickness Control Accuracy (±0.1–0.15mm)
Hydraulic Servo Closed-Loop System: High-response servo cylinders per platen zone (position resolution 0.01mm) for real-time belt deflection compensation
Online Thickness Monitoring: Gamma/X-ray thickness gauges scan full panel width every 10s, feeding data to PLC for gap adjustment
Thermal Expansion Compensation Algorithm: Dynamically corrects pressure settings based on platen temperature field models
3.2 Density Uniformity Assurance
Multi-Zone Pressure Profile Optimization: Auto-adjusts pressure gradient (e.g., 12MPa at entry → 3MPa at exit) based on mat moisture distribution
Fiber Forming-Press Synergy: Airflow speed in former synchronized with press speed, ensuring longitudinal/transverse density CV <3%
3.3 Surface Quality Enhancement
Mirror-Finished Steel Belts: Belt surface roughness Ra≤0.4μm (electrolytic polishing)
Micro-Pressure Zone Control: 0.5-1MPa micro-pressure section at press exit eliminates surface springback
3.4 Dimensional Stability Reinforcement
Gradient Cooling System: Zoned temperature control (20–60℃ adjustable) on cooling star rollers suppresses internal stress warping
Equilibrium Moisture Content Control: Post-processing humidity conditioning chamber (RH 45–55%)
3.5 Production Consistency Guarantee
Digital Twin System: Virtual press model using real-time data (temperature/pressure/speed) to predict panel performance and optimize parameters
AI Quality Alert: Machine learning analyzes historical data to identify thickness deviation trends for preemptive intervention
3.6 Thermal Field Precision
Zoned Temperature Control:
• Entry zone: 210±1℃ (accelerates resin flow)
• Calibration zone: 190±0.5℃ (precision curing)
Belt Temperature Compensation: IR thermography → Auto-adjusts thermal oil flow
Ⅳ. Industrial Value of High-Precision MDF Continuous Press
Material Utilization Increase: Reduces sanding allowance (from 0.5mm to 0.2mm)
Downstream Processing Cost Reduction: Direct suitability for digital printing, thin veneer overlaying, etc.
Energy Optimization: High-precision pressing shortens hot-pressing time by 10–15%, steam consumption ≤1.1 ton per ton of boar
