Wood Technology

Manufacturing Process

From Raw Timber to Finished Board

Every board undergoes a rigorous 8-step production process ensuring consistent quality, stable density, and reliable performance.

01

Log Selection & Grading

Premium logs sourced from FSC-certified sustainable plantations. Each log is graded for diameter, straightness, and defect ratio before processing.

02

Debarking & Conditioning

Logs are debarked using high-pressure water jets and conditioned in steam chambers to optimal temperature for uniform peeling or slicing.

03

Rotary Peeling / Slicing

German and Japanese precision lathes peel veneer at 0.3–3.2mm thickness. Computer-controlled thickness tolerance of ±0.05mm.

04

Veneer Drying

Continuous roller dryers reduce moisture content to 8–12%. Automated moisture sensors ensure uniform drying across every sheet.

05

Gluing & Assembly

Precision glue spreaders apply WBP phenolic or MR urea resin at controlled rates. Cross-grained lay-up for dimensional stability.

06

Hot Pressing

Multi-opening hydraulic presses apply 120–180°C heat and 1.2–2.0 MPa pressure. Computer-controlled time-pressure-temperature curves.

07

Sanding & Calibration

Italian wide-belt sanders calibrate thickness to ±0.1mm. Both faces sanded to 180-grit for a smooth, uniform surface.

08

QC Inspection & Packing

100% visual and dimensional inspection. Random batch testing for MOR, MOE, bonding strength, and formaldehyde emission.

Quality Assurance

Rigorous Testing & Control

Our in-house laboratory performs comprehensive testing at every production stage to guarantee product performance and compliance.

Density Testing

Uniform density verification across each board. Target: 550–680 kg/m³ (plywood), 650–750 kg/m³ (MDF), 620–700 kg/m³ (particle board).

Moisture Content

Precision moisture meters at receiving, post-drying, pre-pressing, and final QC stages. Target: 8–14% depending on product type.

Bonding Strength

Shear testing per EN 314 / JAS standards. WBP glue must withstand 72-hour boil cycle with ≥0.7 MPa bond strength retention.

Emission Testing

Formaldehyde emission tested via desiccator method (JIS A 1460) and chamber method (EN 717-1). E0, E1, CARB P2 compliance.

Bending & Modulus

MOR/MOE testing per EN 310 using universal testing machine. Ensures structural-grade performance for load-bearing applications.

Thickness Tolerance

Laser measurement systems verify thickness tolerance of ±0.2mm for sanded panels. 100% inspection, not just statistical sampling.

Sustainability

Eco-Friendly Manufacturing

Environmental responsibility is embedded in every aspect of our operations. We source timber exclusively from FSC-certified sustainably managed forests, ensuring zero contribution to illegal logging or deforestation.

Our manufacturing process recovers and reuses 98% of wood waste — bark and offcuts fuel our biomass boilers that power the drying kilns, while sawdust is processed into fuel pellets.

All adhesives are low-emission formulations meeting E1/E0 and CARB Phase 2 standards. We continuously invest in cleaner technology to reduce our environmental footprint.
