Before wood becomes furniture, it has to go through many times of chopping and chopping, or even crushing. We should not only keep the beauty of wood, but also get rid of its "temper". Because of the characteristics of wood itself, solid wood furniture will crack and deform. The so-called "no splitting, no solid wood". Making the wood more stable is the core of the panel.
According to the size requirements of the parts and components of the product, carry out primary wood processing and material selection.
Cutting is to cut the required size of wood. Cut the specified size width according to the size requirements.
This is also an important part of material selection. Unqualified materials will be selected in the first step, because they will directly affect the quality and effect of products.
After the wood is processed in length and width, it needs to be processed in thickness. This completes the first step of primary selection, and then the wood after primary processing is cut by multiple saws. In order to make the panel seamless splicing, we use the full-automatic trimming saw. To ensure the panel beautiful, we need to strictly compare and splice the color and texture of each component to ensure the quality of the product.
In order to avoid this problem as much as possible, we need to pay attention to the process of "panel splicing", that is, cutting the whole board into several pieces, and then splicing them together, so that the defective part of the wood can be removed, and the expansion and contraction coefficient of the wood can be reduced, and the stability can be improved.
In order to create high-quality wood products, there are strict requirements on the panel technology.
1. Consistent thickness
The planing and repairing value of wood is the basic requirement to ensure the quality of panel, which must be strictly in accordance with the process index to ensure the consistency of the thickness of single board.
2. Same color
The color difference is the most intuitive factor that leads to the quality of the panel. The panels with roughly the same color and grain shall be selected strictly for splicing; the coating shall be evenly applied to prevent the gap between the panels.
3. Orderly pressurization
When using the panel splicing machine for panel splicing, first add auxiliary pressure to flatten the board, and then add down pressure to compress it; when disassembling, first remove the pressure, and then release the auxiliary pressure to prevent the newly pressed panel from cracking due to incomplete finalization.
High frequency panel equipment, using high frequency panel heating, two-dimensional pressure, can be used for panel, wood edge sealing, L-shaped door set line combination, door core panel splicing. It can solve the problems of heating speed, heating efficiency, automatic production, environmental protection and safety in the process of panel assembly more efficiently.
However, the problem of cracking and deformation of solid wood furniture can not be completely solved only by panel splicing technology, especially after experiencing plum rainy season in the South or heating baking in the north for a long winter, the solid wood furniture is still prone to cracking and deformation.
The stability of wood can be greatly improved by combining the panel lamination technology and solid wood curing technology into the production of solid wood furniture. The recompression process shall be carried out after the completion of panel splicing. First of all, the assembled plates are naturally cured to make the properties of the plates more stable, and the bonding strength between the plates reaches the best state.
In order to ensure the stability of product quality and reduce the probability of furniture cracking, the continuous improvement and exploration of solid wood panel technology, re pressing technology and health preservation technology can make the product almost perfect in the future.
