From Log Deck to Load-Out —
What Happens Between Changes Everything.
Every sheet that leaves this plant has been pressed, calibrated, and documented to tolerances your engineering team can stake a project on. Walk the line.
Eight Checkpoints.
Zero Assumptions.
Every panel is the output of a documented production chain. The data below is the same data our QC team records every shift — not a marketing summary.
Log Preparation & Hydrothermal Conditioning
Logs are sorted by species and diameter, debarked to remove mineral residues, then soaked in heated water pools to soften fibers and reduce lathe checks during peeling.
| Parameter | Specification | Tolerance |
|---|---|---|
| Soak Temperature | 40 – 60 °C | ± 2 °C |
| Soak Duration | 12 – 48 hrs | Species-dependent |
| Log Diameter | 20 – 65 cm | Visual + caliper |
| Bark Residue | < 0.5% | Zero tolerance |
Rotary Veneer Peeling
Conditioned logs are chucked onto rotary lathes and peeled against a precision knife. Consistent knife angle and nose-bar pressure are the primary determinants of veneer quality.
Incorrect knife/nose-bar settings are the primary cause of lathe checks and split veneers. This checkpoint is audited on every lathe shift change.
| Parameter | Specification | Tolerance |
|---|---|---|
| Veneer Thickness | 1.0 – 3.0 mm | ± 0.05 mm |
| Knife Angle | 20 – 22° | ± 0.5° |
| Nose-Bar Pressure | 110 – 130 kPa | ± 5 kPa |
| Lathe Speed | 80 – 200 rpm | Log-diameter curve |
Clipping & Optical Grade Assessment
Green veneer ribbons pass through automated clippers that remove knots, splits, and edge defects. Optical scanners classify each sheet into grade bins before drying.
| Parameter | Specification | Tolerance |
|---|---|---|
| Knot Diameter (A) | 0 mm | None permitted |
| Knot Diameter (B) | ≤ 25 mm | Repaired flush |
| Sheet Width | 1,220 mm std. | + 5 / – 0 mm |
| Split Length | 0 (A) | Per grade table |
Veneer Drying
Green veneer enters continuous roller dryers at 160 – 180 °C. Exit moisture content is measured per sheet; off-spec sheets are re-dried or rejected.
| Parameter | Specification | Tolerance |
|---|---|---|
| Dryer Temp | 160 – 180 °C | ± 5 °C |
| Exit Moisture | 7 – 8 % | ± 1 % |
| Green MC Entry | 50 – 80 % | Species range |
| Warp Flatness | < 2 mm/m | Reject > 4 mm/m |
Adhesive Application & Cross-Grain Layup
Dried veneers are coated with resin by roller spreaders, then stacked in cross-grain orientation. Odd ply counts ensure balanced panels. Glue type is matched to end-use specification.
E0-grade UF adhesive used for interior applications. PF resin mandatory for exterior/structural grades per APA PS 1-19.
| Parameter | Specification | Tolerance |
|---|---|---|
| PF Glue Spread | 160 – 180 g/m² | ± 10 g/m² |
| UF Glue Spread | 140 – 160 g/m² | ± 10 g/m² |
| Open Assembly Time | ≤ 20 min | Gel test each batch |
| Ply Orientation | 90° alternating | Zero misalignment |
Hot Press Cure
Assembled panels load into multi-opening hot presses. Temperature uniformity across the platen is the critical variable — cold spots cause bond failures. Cycle time is controlled to prevent precure.
Panels failing platen temperature uniformity ±2.5 °C are quarantined for delamination testing before release.
| Parameter | Specification | Tolerance |
|---|---|---|
| Press Temperature | 120 – 150 °C | ± 2.5 °C |
| Press Pressure | 14 kg/cm² (200 psi) | ± 5% |
| Load Time | < 2 min | Hard limit |
| Full Pressure Ramp | < 60 sec | Hard limit |
Calibration Sanding & Edge Trimming
Post-press panels are trimmed to final dimensions and run through wide-belt sanders that calibrate thickness across the full panel width. This step eliminates veneer-to-veneer step variations.
| Parameter | Specification | Tolerance |
|---|---|---|
| Thickness Tolerance | Nominal ± 0.2 mm | APA PS 1-19 §5.3 |
| Surface Roughness | ≤ Ra 3.2 µm (A) | Ra 6.3 µm (B) |
| Panel Squareness | ≤ 1.5 mm diagonal diff. | Reject > 3 mm |
| Edge Straightness | ± 0.5 mm / 2,440 mm | Reject outside |
Final Grading & Mechanical QC
Every panel receives a grade stamp. Random-sample mechanical testing covers Modulus of Rupture, Modulus of Elasticity, and shear-through-the-thickness. Bond integrity is tested via the boil test for exterior grades.
| Parameter | Specification | Tolerance |
|---|---|---|
| MOR (Structural) | ≥ 24 MPa | Batch average |
| MOE (Structural) | ≥ 9,500 MPa | Batch average |
| Bond Shear (PF) | ≥ 1.0 MPa post-boil | Per APA PS 1-19 |
| Formaldehyde (E0) | ≤ 0.05 ppm | CARB P2 limit |
