1) PINE LVL Quality Control
1. Dry the veneer: Require our pine veneer supplier dry the veneer MC below 8%. We will check it when the material comes into our factory, we will dry the veneer by the kiln or hot press machine again once some veneer MC above 8%.

4. Lay up: lay the veneer plies according to the thickness of finished goods. 39MM will be 18 layers. (veneer thickness is about 2.40MM)
5. Hot press: press the LVL by hot press machine, the temperature is about 130° C,and the pressure is about 9kgs/cm2. The time in the winter is about 2 hours long.
6. Nursing: keep it 3-5 days for nursing.
7. Strength test: 1.8MM LVL, 210kgs weight , the bending can not be more than 2CM. Boiling test , no delamination up to the Type I standard.
8. Sanding: use the sanding machine to sand the LVL, keep the right thickness(39MM , no minus) and let it smooth and beautiful .
9. Cutting and moulding: use the multi-cutting machine to cut into the required size(230MM plus/minus1MM). profile the edge of 45° angle.
10. Packing: print blue finish on the two ends of LVL and print the words LAP-PLANK AS1577 WLLL210KG MAX SPAN 1.8M on the thickness side. use the pallet to pack it. Wrapped with plastic bag. The packing should be very strong worthy of ocean shipment.
