It is the cooling of the hot pressing plate (1-3 weeks). When the hot-pressed decorative veneer is transported out of the hot press, the surface temperature is about 85 degrees, but the room temperature is very low. The temperature difference between the inside and outside of the veneer is very large, which makes the veneer produce thermal stress. In the process of hot pressing and cooling, the movement of water in the floor will also produce moisture content stress. If the veneer is not cured and cooled to room temperature, it will bend the board surface, affect the flatness of the board surface and deform the edge of the board surface.

Pure hand tour, hope to adopt.
