Product Description
Ⅰ.Continuous pressing machine for artificial boards
1. Core Definition
The Continuous Pressing System is the core equipment in artificial board (MDF/Particleboard/OSB) production lines. It conveys the mat continuously via steel belts or heated platens, achieving high-temperature and high-pressure forming during dynamic movement, replacing traditional intermittent multi-opening presses.
2. Core Structure
| Component | Function Description |
| Steel Belt System | Heat-resistant alloy belts (1.5-2.5mm thick), withstand pressure ≥5MPa, surface temp 200-230℃ |
| Heated Platen Modules | Zoned heating (20-30 zones), independent temp control (±1℃), hydraulic zoned pressure (±0.2MPa) |
Hydraulic Station | High-pressure plunger pumps (28-35MPa), response time ≤0.5s |
| Tensioning Device | Automatic hydraulic compensation for belt elongation, maintaining constant tension (<5% fluctuation) |
3. Workflow
3.1 Feeding: Pre-pressed mat enters from forming station
3.2 Pressing Stages:
High-Pressure Zone: Peak pressure (4-5MPa) at entry for rapid compression
Thickness-Control Zone: Gradual pressure reduction (2-3MPa) to target thickness
Curing Zone: Low pressure (0.5-1MPa) for resin polymerization
3.3 Output: Boards exit continuously at 20-100m/min
4. Technical Advantages
Efficiency Boost: 300% higher output vs. multi-opening presses (annual capacity up to 600,000m³)
Energy Saving: Heat recovery reduces consumption by 15-20% (steam usage ≤1.6 tons/m³ board)
Quality Enhancement: Thickness tolerance ±0.1mm, density variation ≤3%
Eco-Friendliness: Enclosed production reduces formaldehyde emissions (workshop air ≤0.05mg/m³)
Ⅱ. Auto-Calibration System for Continuous Board Presses
1. Core Function
Real-time monitoring of board thickness and density distribution during high-speed production (20-100m/min), with closed-loop control to automatically adjust press parameters, ensuring:
Thickness control: ±0.1mm
Density variation: ≤3%
Flatness: ≤0.2mm/m
2. System Components
Module | Technical Solution |
Online Detection | γ-ray thickness gauge (0.01mm precision) or laser scanner (1000 pts/sec) |
Pressure Control | Hydraulic servo valves (≤10ms response) managing 200+ pressure zones |
Temp Compensation | Infrared thermal imaging + zoned platen temp adjustment (±1℃) |
Central Controller | Real-time OS (RTOS) with <5ms latency |
3. Calibration Process
4. Key Technologies
Dynamic Pressure Compensation
Adjusts pressure curve based on moisture (microwave sensor) and thermal expansion prediction
Steel Belt Deformation Correction
Laser profilometers detect belt flatness, hydraulic cylinders auto-compensate (±0.05mm)
Big Data Optimization
AI models trained on historical data optimize pressure-temperature profiles (+3-5% yield)
5. Performance Metrics
Indicator | Pre-Calibration | Post-Calibration | Improvement |
Thickness Yield | 0.895 | 0.992 | 0.097 |
Press Downtime | 7.2/month | 1.5/month | -0.79 |
Raw Material Waste | 4.8t/10k m³ | 2.1t/10k m³ | -0.56 |
Ⅲ.Artificial Boards
Artificial Boards (Engineered Wood Products) are panels manufactured by physically and chemically processing and reconstituting raw materials such as wood or non-wood plant fibers. They overcome the size limitations and defects of natural timber, offering advantages like standardized specifications, controllable performance, and high resource utilization efficiency.
Main Types and Characteristics
1. Plywood
Structure: Composed of an odd number of veneers (thin wood sheets) glued and pressed with their grain directions perpendicular to adjacent layers.
Characteristics:
High bending strength, good dimensional stability
Water resistance grades (WBP/Weather-resistant, MR/Moisture-resistant)
Applications: Concrete formwork, furniture back panels, ship decks.
2. Fiberboard
Raw Material: Wood fibers (from wood processing residues).
Classification:
Type | Density (kg/m³) | Characteristics | Applications |
Hardboard | >900 | Smooth surface, high strength | Furniture doors, laminate flooring |
MDF (Medium Density Fiberboard) | 650-800 | Easy to machine, suitable for carving | Custom furniture, cabinets |
Softboard | <450 | Sound/thermal insulation, low strength | Acoustic panels, packaging liners |
3. Particleboard
Structure: Formed by hot-pressing wood chips or particles bonded with adhesive.
Grades:
Standard Particleboard: Furniture substrates, packing cases
-OSB (Oriented Strand Board): Long wood strands oriented during layup, high mechanical strength, used for structural wall sheathing.
Advantages: Low raw material cost, high eco-friendliness (can use recycled wood).
4. New Eco-friendly Boards
Formaldehyde-Free Boards: Use MDI adhesive (isocyanate) instead of urea-formaldehyde resin, formaldehyde emission ≤0.03mg/m³ (far superior to E0 grade).
Bamboo Scrimber: Reconstituted and glued bamboo strips, strength 2x that of hardwood, used in high-end furniture.
Core Production Processes
1. Raw Material Preparation
Wood → Chipping → Screening → Fiber separation (fiberboard) / Particle preparation (particleboard)
2. Adhesive Application & Additives
Adhesives: Urea-formaldehyde (UF), Phenol-formaldehyde (PF), MDI resin
Additives: Flame retardants (e.g., Al(OH)₃), anti-mold agents
3. Forming & Hot-Pressing
Mat Forming: Air/mechanical forming, determines density uniformity
Hot-Pressing: Temperature 120-220°C, Pressure 2-5MPa, Time adjusted by thickness (~0.4 min/mm)
4. Post-Processing
Sanding (precision ±0.1mm) → Trimming → Surface finishing (melamine paper, wood veneer)
Performance Comparison
Parameter | Solid Wood | Plywood | MDF | OSB |
Bending Strength | Medium | High | Medium | Very High |
Moisture Resistance | Prone to warping | Good (WBP grade) | Requires treatment | Excellent |
Machinability | Grain-dependent | Edge splitting | Carving/curving | Edge chipping |
Eco-friendliness | Formaldehyde-free | E1/E0 grade | Mostly E1 | Low formaldehyde (PF resin) |
Application Fields
Building Structures: OSB for wall sheathing, glulam beams/columns
Furniture Manufacturing: MDF for carved cabinet doors, particleboard for wardrobe bodies
Transportation: Container flooring (bamboo plywood), high-speed train interiors (flame-retardant MDF)
Innovative Applications:
Acoustic Panels: Perforated MDF + sound-absorbing cotton, for concert halls
Anti-static Flooring: Carbon fiber-reinforced MDF, for data centers
