2. Strand Preparation Section Equipment
Drying System: Utilizes high-efficiency triple-pass or single-pass rotary drum dryers. Using hot flue gas as the medium, it uniformly reduces the moisture content of the strands from ~50% to a precise range of 2-4%, a critical prerequisite for ensuring moisture resistance. The system is equipped with heat recovery units, significantly reducing energy consumption.
Blending System:
Blender: The high-speed continuous blender is core equipment. Dried strands are thoroughly and uniformly mixed with moisture-resistant PMDI/MDI isocyanate resin or modified moisture-resistant MUPF resin. The system features high-precision metering pumps and flow sensors to ensure absolute accuracy in the resin-to-wood ratio, which is central to achieving the board's moisture resistance, high strength, and eco-friendly grade.
Wax Application System: An independent metering system that adds liquid wax simultaneously with resin to further enhance the board's waterproof and moisture-resistant properties.

3. Forming and Pre-Pressing Section Equipment
Forming System: A core piece of equipment. Uses mechanical or pneumatic orienting forming heads to lay the resinated strands onto a moving caul plate in a oriented structure (face layers longitudinally, core layer crosswise), forming a uniform and symmetrical mat. This structure determines the anisotropic mechanical properties of the OSB board.
Pre-Press: A continuous belt pre-press applies initial compression to the fluffy mat, increasing its handling strength for safe transport to the hot press and reducing steam blow-out during pressing.

4. Pressing and Finishing Section Equipment
Pressing System:
Multi-Opening Hot Press: The "heart" of the production line. Typically configured with 8-12 or more openings to meet the 300m³/day capacity requirement. It employs high temperature (200-220℃) and high pressure (>100 Bar) to permanently cure the resin and compact the mat into a high-density board within a short time. The press is equipped with press stops and a PLC control system to ensure precise and consistent thickness tolerance for every board.
Steel Belts and Loader/Unloader System: Fully automatic loaders feed the mat into the press and unload the pressed boards, enabling continuous production. High-temperature steel belts ensure smooth and flat board surfaces.
Cooling and Conditioning System:
Star Cooler: Separates the high-temperature boards (~200℃) coming out of the press sheet by sheet and cools them with air, stopping the thermo-chemical reaction and stabilizing internal stresses to prevent warping.
Conditioning Warehouse: Cooled boards are stacked and stored for 24-48 hours to allow further equilibration of internal moisture content and stress, achieving optimal final performance.

5. Sawing and Packaging Section Equipment
Cross-Cut and Rip-Saw System: Uses large-scale double-cut sanding saws or cross-cut/rip-saw production lines to accurately cut the large-format rough boards into market-required sizes (e.g., 1220x2440mm, 1250x2500mm).
Stacking and Packaging System: Fully automatic stackers sort boards by specification and grade. An automatic packaging line then bundles them with plastic film and edge protectors, ensuring safe transportation.

6. Central Control System
The entire line is controlled by a Central PLC + Industrial Computer system, integrated into a control room. Operators can monitor all equipment parameters (temperature, pressure, speed, resin dosage, etc.) via the Human-Machine Interface (HMI), enabling recipe management, fault diagnosis, production data recording, and analysis. This ensures efficient, stable, and quality-controlled production.

Production process
This production process is a highly automated and continuous operation, spanning from raw logs to packaged finished products through multiple precisely controlled sections. The core of the process lies in the oriented forming and high-temperature pressing technology, coupled with moisture-resistant resins, to ultimately produce structurally stable, high-strength OSB boards with excellent moisture resistance.
Phase 1: Raw Material Preparation
1. Debarking & Chipping
Logs are fed via conveyor chains into a large drum debarker to remove bark (which can be used as fuel for the thermal energy center).
Debarked logs are then sent to a large disc or drum chipper to be cut into standard, uniform wood strands/flakes.
2. Screening & Storage
The strands are graded through multi-deck vibrating screens, separating oversized, undersized, and acceptable strands.
Oversized strands are sent back to a re-crusher; undersized strands can be used as fuel or for other boards; acceptable strands are sent to storage silos for later use.
3. Drying
Acceptable strands are conveyed via belt conveyors into a triple-pass rotary drum dryer.
Using hot flue gas (typically from a thermal energy center burning waste like bark and sander dust), the moisture content of the strands is precisely and uniformly reduced from ~50% to a critical 2-4%. This is a key prerequisite for ensuring effective resin blending and the final board's moisture resistance.
Phase 2: Blending & Forming
4. Blending - The Key Moisture-Resistance Step
Dried strands are fed into a high-speed continuous blender.
Here, strands are uniformly mixed with moisture-resistant resin (typically PMDI/MDI (isocyanate) or modified moisture-resistant MUPF resin). PMDI resin offers superior bonding strength and is inherently waterproof, making it core to the board's exceptional moisture resistance.
Liquid wax is also added precisely to further enhance the water-repellent properties.
5. Oriented Forming
The resinated strands are formed into a three-layer mat on a moving caul plate by an orienting forming head.
The forming head, using mechanical or pneumatic means, orients the strands: face layers along the production line direction (longitudinal) and the core layer perpendicular to it (transverse). This "cross-oriented" structure is the source of OSB's high strength and dimensional stability.
6. Pre-pressing
The fluffy mat enters a continuous belt pre-press, where it is initially compacted into a mat band with sufficient handling strength for transport and to reduce steam blow-out during hot pressing.
Phase 3: Pressing & Finishing
7. Hot Pressing - Curing & Molding Stage
The pre-pressed mat is cut and loaded by an automatic loader into a multi-opening hot press (typically 8-12 openings).
Under high temperature (200-220℃) and high pressure (>100 Bar), the resin cures rapidly within seconds or minutes, permanently bonding the strands into a high-density board. Press stops exercise strict control over the final thickness of each board.
8. Cooling & Conditioning
The freshly pressed hot boards are fragile and must be immediately cooled and separated in a star cooler to stop the thermo-chemical reaction, stabilize internal stresses, and prevent warping.
Cooled boards are stacked and stored in a conditioning warehouse for 24-48 hours to allow internal temperature and moisture to equilibrate, achieving optimal final mechanical properties and stability.
Phase 4: Sizing & Packaging
9. Sizing
The conditioned rough-edged boards are sent to a cross-cut and trim saw line where they are precisely sawn by sanding saws or circular saws into market-required sizes (e.g., 1220x2440mm, 1250x2500mm).
10. Inspection & Packaging
Boards are graded for quality by online inspection systems (e.g., weighing, thickness measurement).
Qualified boards are stacked by automatic stackers and then tightly packaged by a packaging line using stretch film and edge protectors to prevent moisture ingress and damage during transportation, before finally being labeled.
The entire process is monitored and scheduled in real-time by a Central Control System (PLC), ensuring the 300m³/day production capacity is achieved efficiently and stably.
