5. Production Processes & Joinery Methods
Process | Description | Quality Control Check |
---|
Kiln Drying | Reduces moisture to 8-12% | Moisture meter verification |
Planer Milling | Shapes profiles (e.g., baseboard, crown) | CNC precision (±0.5mm tolerance) |
Finger Jointing | End-to-end splicing for long lengths | Glue line strength ≥ wood strength |
Sanding | 120-220 grit for smoothness | Visual & touch inspection |
Finishing | Staining/varnishing (spray/dip) | Even coating, no drips/bubbles |
Common Joinery Methods:
- Butt Joint (Simple end-to-end, glued/nailed)
- Miter Joint (45° angle cuts for corners)
- Spline Joint (Reinforced with a wooden strip)
- Tongue & Groove (Interlocking edges for stability)
Notes:
- All test results should comply with international standards (e.g., ANSI, EN, ISO).
- Rejected batches must be reworked or discarded based on defect severity.
