How To Control The Deformation in The Production Of Wooden Collection Boxes?

The manufacturer of wooden collection boxes stated that in our years of production experience, we often find that even if the wood is already dry, it will invade the wood pores due to the humidity in the air during storage, which can also lead to secondary deformation of the wood. In the production process, we do not want to encounter the problem of wood deformation, but sometimes we simply cannot predict and control the changes in humidity in the air. We can only take more than one defensive measure, but we cannot guarantee 100% deformation. The deformation amount should not exceed the industry standard of 1.5mm as much as possible. Below is an introduction to how to control the deformation in the production of wooden collection boxes:

The reason for wood warping and cracking is that wood has the characteristics of moisture expansion and dry shrinkage. The law is that when the moisture content of wood is lower than the fiber saturation point, the volume of wood expands; As the moisture content decreases, the volume of wood shrinks, and its longitudinal and transverse length dimensions shrink. Transverse shrinkage can be divided into radial and tangential directions. Especially, there is a significant difference in the proportion of longitudinal and transverse shrinkage of wood. Usually, the longitudinal drying shrinkage is about 0.1%, the transverse drying shrinkage is relatively large, the tangential drying shrinkage is as high as 12%, and the radial drying shrinkage is about 3%~6%.

Therefore, the difference between the longitudinal and transverse drying shrinkage of wood will generate tensile stress along the tangent direction of the tree ring during drying. When the tensile stress is greater than the force cohesion between wood cells, the wood will undergo warping deformation and cracking.

2. The wood should be dried and its water content should be controlled at a level suitable for the local average air humidity to reduce the excessive water exchange between air and wood. In order to maintain relative balance, the wood is not easy to crack and deform. The national regulations stipulate that the moisture content of wood is between 8% -12%, which is to effectively control the deformation and cracking problems in the production of wooden collection boxes.

3. The surface of the wood should be sealed to isolate moisture and dry exchange between the wood and the air. The humidity and dryness inside and outside the wood should be consistent to maintain its stability and achieve the goal of controlling deformation and cracking in the production of wooden collection boxes.

4. Inconsistent drying and humidity of wood will inevitably lead to deformation or cracking of finished furniture. After general drying, the wood needs to be stored for several months or even more, and after sufficient exchange, the drying and humidity inside the wood should be consistent with that in the air, providing a layer of protection for the wood. However, changes in dryness and humidity in the air still have an undeniable impact on wooden stairs, and paint is the second layer of protection against deformation.

The use of wooden collection boxes has an aesthetic effect, especially in improving product grade, which will promote product sales. If this packaging is used to package gifts, it can demonstrate more sincerity and improve the quality of the gift. All types of products are packaged in wooden boxes, which can present a more primitive and atmospheric texture and showcase the charm of ancient culture. Wooden collection boxes not only have practical value, but also have good economic and ornamental value. Wooden collection boxes have a good protective effect on the items inside the packaging, as wooden boxes are usually sturdy, durable, and have good stability without worrying about damage or deformation. The protection of internal products to enhance functionality is very strong, so there is no need to worry about damage to internal products during transportation and storage.
