The latest technology of plywood production

1. After rolling both sides of the veneer with a needle roller, use an inclined punch to cut it into a tooth shape along the end of the veneer.

2. Take an untreated veneer as the surface layer and spread it on the chopping board as the first layer. Then, stick a veneer with toothed ends on both sides and spread it along the vertical direction of the first layer of butt joint. The teeth are meshed with each other to form an intermediate layer, and the subsequent intermediate layers are respectively spread along the vertical direction of the first intermediate layer veneer butt joint, and the last layer is laid with the first layer.

3. Then make the board base in 15- 17MPa, 95-10℃ for hot pressing 15-25 minutes, then glue the two sides of the board base, and then at 18MPa, 95.

The invention can solve the defect that the finished board is easy to warp and deform, improve the tensile strength of the finished board and increase the bending strength of the finished board at the same time.
