2. Production Process of Wood-Based Panels Furniture
2.1 Raw Material Preparation & Grading
- Material Sourcing:
- Particleboard, MDF (Medium-Density Fiberboard), Plywood, or OSB (Oriented Strand Board) sourced from certified suppliers.
- Veneers (if applicable): Graded by thickness, grain pattern, and defects (e.g., knots, cracks).
- Pre-Treatment:
- Moisture control: Kiln-drying to 6–10% moisture content.
- Adhesives: CARB Phase 2 compliant or formaldehyde-free (E0/E1 standards).
2.2 Manufacturing Workflow

- Edge Banding: PVC/ABS or real wood edges applied (hot-melt adhesive).
- Drilling & Machining: Precise holes for fittings (e.g., hinges, screws).
- Surface Finishing:
- Lamination (HPL/CPL), veneering, or painting (UV/PU coatings).
- Assembly: Hardware (hinges, slides) installed; structural integrity checked.
- Packaging: Foam/corner protectors; moisture-resistant wrapping.
3. Quality Control (QC) & Common Defects
3.1 QC Checkpoints
- Raw Material Inspection:
- Panel flatness, thickness tolerance (±0.2mm).
- Adhesive certification (formaldehyde emissions ≤0.05ppm for CARB2).
- In-Process QC:
