QC Process

Stage 01

Raw Material Inspection

• Log species, diameter and moisture content checked before peeling
• Only selected veneers released to production

Stage 02

Core Preparation & Assembly

• Veneer moisture controlled within 8–12% to prevent delamination
• Veneers sorted by thickness and surface appearance

Stage 03

Glue Application & Pressing

• Adhesive mixed to formula per plywood type (MR, WBP, melamine)
• Glue uniformity and spread checked before pressing
• Cold and hot press temperature, pressure and time controlled

Stage 04

Dimensional Inspection

• Panel size tolerance and thickness calibration checked
• Moisture content checking
• Surface defect checking sheet by sheet
• Core checking sheet by sheet
• Bending strength testing randomly
• Cut into small sheets to test glue bond and core inside
• Panels with cracks, overlaps or uneven surfaces rejected

Stage 05

Surface & Bonding Tests

• Random bond testing according to EN 314-2
• Surface smoothness and film quality inspected

Stage 06

Final QC & Packaging

• 100% of panels inspected for surface, labelling and packing condition
• Final moisture and bonding strength tests before shipment
• Ensure packaging follows PPWR requirements
