How To Prevent Deformation Of Your Packing Box Shape

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 increased. This is due to the low density of the wood and the moisture easily ruled out.

Material temperature The bending performance of wood increases with the increase of wood temperature, but when the temperature of wood is too high, the plasticity of wood increases and the hemicellulose in wood degrades, reducing the strength of wood.

After the bending speed is softened, the straight square material must be bent immediately. If the bending speed is too slow, the temperature of the wood will drop 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 will be too late The need to adapt to deformation leads to 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 layer will not be damaged. The wheel layer is prone to slippage and reduces the bending performance of the wood.

When the thickness and width of the linear square timber are relatively large, the wood is easy to lose stability when it is bent. Therefore, in actual production, the width of the square timber can be used to make multiple wool. When the linear square timber wool After bending, splitting is performed.
