Ⅰ.Core Host System
Module | Configuration Requirements | Function |
1. Mirror-Finished Steel Belt | - Material: High-nickel alloy steel (Surface hardness ≥ HRC 62) | Direct contact with mat for heat/pressure transfer; defines initial surface smoothness |
- Roughness: Ra ≤ 0.1μm (Laser-polished) | ||
- Tension control: Servo motor ±1% dynamic adjustment | ||
2. Multi-Stage Pressure System | - Pressure zones: ≥40 independent hydraulic zones | Eliminates edge looseness; density deviation ≤±2% |
- Control accuracy: ±0.5 bar | ||
- Edge pressure boost: +10% compensation | ||
3. Precision Temperature Control | - Temperature zones: ≥50 zones | Optimizes resin curing; minimizes pre-cured layer |
- Control accuracy: ±1℃ | ||
- Heat transfer medium: High-purity synthetic thermal oil (300℃ rated) | ||
4. Thickness Control System | - Laser thickness gauge resolution: 0.01mm | Full-width thickness tolerance ±0.05mm |
- Closed-loop response time: ≤0.1s |
Ⅱ.Critical Differences (Furniture-Grade MDF VS Ordinary MDF)
1. Steel Belt System (Key to Surface Smoothness)

Parameter | Standard MDF Press | Furniture-Grade MDF Press | Impact |
Belt Surface Roughness | Ra ≤ 0.4μm | Ra ≤ 0.1μm (mirror finish) | Directly defines initial surface gloss |
Belt Material | Standard alloy steel | High-nickel alloy steel (wear/corrosion-resistant) | Prevents scratches, extends lifespan |
Tension Control Accur. | ±5% | ±1% | Eliminates micro-vibrations causing surface ripples |
2.Pressure Control System (Density Uniformity)
Hydraulic station for continuous hot press
Hydraulic station for continuous hot press
Parameter | Standard MDF Press | Furniture-Grade Press |
Pressure Zones | 15–25 zones | 30–50 zones (finer gradient) |
Pressure Control Accuracy | ±2 bar | ±0.5 bar |
Edge Pressure Boost | None or basic | Patented edge compensation (+10% pressure) |
3.Temperature Control System (Curing Quality)
Parameter | Standard MDF Press | Furniture-Grade Press |
Temp. Control Zones | 20–30 zones | 40–60 zones |
Temp. Fluctuation Range | ±3°C | ±1°C |
Heat Transfer Medium | Standard thermal oil | High-purity synthetic oil (15% higher efficiency) |
4.Upgraded Ancillary Systems (Low-Defect Assurance)
System | Furniture-Grade Configuration | Purpose |
Fiber Preparation | Ultra-fine fiber screening (oversize ≤3%) | Eliminate surface fiber clumps |
Resin Application | High-precision atomization (deviation ≤±0.8%) | Prevent glue spots/clouding |
Mat Forming | Dual-head air forming + magnetic leveling (density dev. ≤±2%) | Avoid pre-cured layers |
Inline QC System | Laser surface scanner (real-time Ra/flaw detection) | Instant defect rejection |
Ⅲ.Process Parameter Comparison
Process Stage | Standard MDF | Furniture-Grade MDF |
Pressing Temp. | 200–210°C | 180–220°C (zoned) |
Specific Pressure | 250–350 bar | 300–500 bar (mid-zone) |
Mat Moisture | 10–12% | 8–10% (reduce steam explosion) |
Sanding Allowance | 0.15–0.2mm/side | 0.2–0.3mm/side (fully remove pre-cured layer) |
Ⅳ.The surface smoothness realization process of furniture-grade MDF
Hot pressing stage: The mirror steel strip is directly pressed to form an initial smooth surface (Ra ≈ 0.8-1.2μm).
Sanding stage:
1.The thick sand belt is fixed by four sand frames (the particle size of the sand belt is refined step by step: P80→P150→P240→P320).
2.The final surface Ra value can be controlled to 0.3-0.5μm, meeting the requirements of UV coating or PVC veneer.
