Chipboard production line can be designed to be different production capacity, we can offer you per year 100000m3 capacity as standard 4*8feet size.
What is the Chipboard production process?
Raw material preparation → wood shavings preparation → Drying → sizing → laying → pre-pressing → hot pressing → cooling → edge trimming → Sanding → sorting → packaging and storage
Specific Chipboard production step
Waste raw materials
Drum chipper
1. Raw material preparation
- Raw material type:
Wood waste (branches, sawdust, scraps)
Non-wood fibers (bagasse, straw, requiring special treatment)
- Key technologies:
Raw material sorting system (metal detection + impurity removal)
Moisture content control (initial moisture content ≤30%)
2. Shavings preparation
- Equipment: Drum chipper + ring planer
- Process requirements:
Wood shavings size: Length 10-30mm, thickness 0.2-0.5mm (core layer/surface layer graded treatment)
Pass rate: ≥95% (coarse wood shavings are sieved and recycled)
Rotary dryer
Drum dryer
3. Drying process
- Equipment: Drum dryer (Biomass fuel/natural gas heating)
- Parameter control
Moisture content after drying: 2-4% for core layer wood shavings and 4-6% for surface layer wood shavings
Temperature: 120-180℃ (To prevent coking)
Vibrating screen
Vibrating sieve
4. Vibrating screen
Automatic screening the wood chips as required size, filter the oversize and undersize wood chips
Resin blender system
Glue system
5. Glue application and mixing
- Adhesive type:
Urea-formaldehyde resin (UF), phenolic resin (PF) or environmentally friendly MDI adhesive (without formaldehyde addition)
- Sizing system
High-pressure atomized spray adhesive (8-12% adhesive content, core/surface layer differentiated ratio)
Add paraffin water repellent (0.5-1%)
Mat forming
Slab paving
5. Paving and shaping
Equipment: Mechanical/air flow paving machine (multi-layer structure paving)
Key points of the process
Gradient structure paving (surface fine wood shavings + core coarse wood shavings)
Density control: 650-750kg/m³ (error ±3%)
Continuous Pre-press
Cross-cut saw
6. Continuous Pre-press and Cross cut saw
Cold press preforming (pressure 1-2 mpa, reducing thickness deviation), and automatic cut the panel as required length
Multi-opening Hot press
Cooling frame
Hot pressing (core process) :
Equipment: Continuous flat press (or multi-layer hot press)
Parameter:
Temperature: 180-220℃
Pressure: 2.5-3.5MPa
Time: Approximately 20-30 seconds per mm for a 3-5mm thick plate
Cooling
Flip plate cooler (reduced to below 40℃ to prevent deformation)
Sanding machine
Edge cutting machine
Edge trimming
Longitudinal and transverse sawing (width 1220×2440mm, tolerance ±1mm)
Sanding
Fixed-thickness sanding (surface flatness ≤0.1mm)
As different clients conditions, such as different raw materials types, glue type, and other factors, we can give a better solution
