1. Continuous flat pressing system
- Dual steel belt synchronous drive technology
- Segmented pressure roller (32-zone precision pressure regulation)
2. Intelligent temperature control module
- Multi-zone independent hot press plate temperature closed-loop control
- Hot oil circulation error ±1.5℃
3. Safety protection
- Automatic deviation correction device for steel belt deviation prevention
- Overload emergency stop + fire sprinkler system
1. Feeding system
After the paved and formed particle board is inspected by the metal detector, it is fed into the press by the servo-driven conveyor belt at a speed of 18-25m/min.
The pre-pressing roller initially compresses the board to an initial density of 300-450kg/m³.
2. Hot Press Forming
Fourth stage pressure control
Region | Pressure (MPa) | Temperature (℃) | Function |
Inlet wedge zone | 0.5-1.2 | 180-200 | Exhaust pre-compression |
Main pressure zone | 3.0-5.5 | 210-230 | Resin curing (UF/MDI) |
Thickness calibration zone | 2.0-3.0 | 200-210 | Thickness tolerance ≤±0.15mm |
Decompression zone | 0.3-0.8 | 190-200 | Stress release and anti-rebound |
Dual steel belt synchronous drive: German SGL carbon fiber reinforced steel belt, life ≥ 5 years
3. Intelligent control
Siemens S7-1500 PLC + WinCC HMI
Real-time monitoring of board density curve (online gamma ray detector)
Continuous Production: Compared to intermittent presses (such as multi-layer hot presses), production efficiency has been significantly improved.
Quality Stability: The pressure and temperature distribution is uniform, the density consistency of the plates is high, the internal stress is small, and the plates are less prone to deformation.
Energy Conservation and Environmental Protection: The heat energy utilization rate is high, the adhesive curing is complete, and the release of formaldehyde is reduced.
Flexibility: By adjusting the pressure curve, it can adapt to the production of plates of different thicknesses and densities.
Comparison Table
Feature | Traditional Hot Press (Multi-layer/Single Opening) | Continuous Press (CP) |
Working Principle | Batch (Cyclical) | Continuous (Steel Belt Conveyance) |
Production Efficiency | Lower (Cycle Time Limited) | Very High (Continuous, Uninterrupted) |
Product Quality | Moderate (Density Uniformity, Thickness Tolerance, Pre-curing Control) | Excellent (Highly Uniform Density, Minimal Thickness Tolerance, Very Thin Pre-curing Layer, Superior & Stable Properties) |
Energy Consumption (per unit) | Higher | Lower |
Raw Material Efficiency | Moderate | Higher (Potentially Lower Core Density/Resin Usage, Less Sanding) |
Automation Level | Medium | High |
Typical Application | Small/Medium Batches, High Variety, Custom Production; Limited Budget | Very Large-Scale, High-Volume Standardized Production; Pursuing Highest Quality & Efficiency |
Application scenarios
1.OSB production line
OSB strand alignment → Pre-press → Continuous hot pressing
2.Manufacturing of moisture-proof boards
MDI adhesive injection → 180°C curing → Moisture-resistant PB
3.Production of ultra-thin plates
2-6mm HDF with ±0.05mm thickness stability
