How to prevent the shape of wooden packaging box from being deformed
The moisture content of the wooden box is within the fiber saturation point of the wood. The bending performance of the wood increases with the increase of the moisture content of the wood. When the density of the wood is small, the moisture content can be appropriately larger. This is due to the low density of the wood and the moisture content. The reason is easy to rule out.
Material temperature The bending performance of wood increases as the temperature of the wood increases, but when the temperature of the wood is too high, the plasticity of the wood increases, and at the same time the hemicellulose in the wood is degraded, reducing the strength of the wood.

After the bending speed is softened, the straight square lumber must be bent immediately. If the bending speed is too slow, the temperature of the wood will decrease and the plasticity will be weakened, which will affect the bending performance of the wood; if the bending speed of the wood is too fast, the internal structure of the wood is too late Adapt to the needs of deformation and cause damage.
The relationship between the annual ring layer and the curved surface When the annual ring layer of the wood is parallel to the curved surface, the wood will not be damaged under greater pressure; but when the annual ring layer is perpendicular to the curved surface, under the bending pressure, the annual ring The wheel layer is prone to slippage, which reduces the bending performance of the wood.
When the thickness and width of the linear square lumber are relatively large, the wood tends to lose stability when it is bent. Therefore, in actual production, the width of the square lumber can be used to make the form of multiple wool. After bending, split processing is carried out.
