For furniture manufacturers, mentioning “custom wood customizationâ€, everyone recognizes that it is an industry with a broad prospective market, and it must be a “cake†that everyone wants to share. However, the development of the industry always hopes to coexist with the crisis. There are some unavoidable problems in the whole wood customization industry. If you can't see through it, you can easily fall into the quagmire of struggle. After seeing it, seeing it clearly, finding the solution is the correct solution.
Many people think that cracks in furniture are due to temperature. The real reason is actually from humidity, not temperature. This is a common misconception.
Deformation of custom wood furniture is an extremely bad experience for many consumers and manufacturers. Many customers don't believe that the whole wood customization will actually have this problem. In the case of not understanding the reasons, the customer first mostly classified the reason as "fake" goods, or there was a problem in the production process of the furniture.
The cause of furniture cracking
First, the characteristics of wood
As long as it is made of real wood, it is normal to have a slight crack. The same is true for the whole wood custom furniture. The wood characteristics are the same, and the non-cracking wood does not exist. Generally, the solid wood will be slightly cracked, but it will not burst, crack, and repair it with a little repair.
Wood is a natural material, and the cells that make up its cells are arranged in a random direction, making the different parts of the wood non-uniform in nature. Wood itself is an unstable material. Even in the same tree species, the same tree, because of the different positions of the sawn timber, the nature of the wood will not be exactly the same.
Second, the process is not in place
Solid wood materials can't be used directly for furniture. The plates must be dried before processing. This is an important step to avoid cracking of solid wood furniture. Now there are many manufacturers, because of equipment, cost and other issues, there is no strict Drying, or insufficient drying time after drying, is used for production.
1. Furniture manufacturers have great problems in the process of drying wood. The poor drying quality, large difference in water content or insufficient health cycle will cause the stress remaining in the wood to act, thus causing cracking or deformation of the wood. Hidden dangers.
2. There are many problems in the production and processing of enterprises. In the production process of furniture, the selection of materials and methods, the way of painting and the use of adhesives will affect the quality of the furniture. If the manufacturer does not handle it properly, it will bury the cracking deformation of the furniture in the future.
Third, improper maintenance and use
Even in the case of normal drying, if it is caused by external factors, it may cause cracking. For example, in the cold winter weather in the north, there is heating in the house. If the custom furniture of the whole wood is close to the heating for a long time, or if the maintenance is not taken care of during the summer, Exposure to the sun in the hot sun, this can easily lead to bursting and deformation of the whole wood custom furniture, thus affecting the service life of wooden furniture.
Solution to cracking and deformation of furniture
As long as it is subjected to a strict and strict drying treatment, the general cracking will not be obvious, and even if there is cracking, it is a very small slit, which usually does not affect the use. If the cracking of the solid wood is not very serious, you can use sandpaper to polish around the cracking place, collect the fine powder that has been polished and fill it in the crack, and seal it with glue. Here are five tips for practical use.
1. Furniture manufacturers should control the moisture content of materials. Furniture manufacturers can introduce a complete set of Sino-Swiss Zhilian material drying equipment, and match the body to ensure that the moisture content of the wood used is at the best 10%-12%. Manufacturers with insufficient conditions should try to purchase materials that have been dried.
2. The production enterprise strictly selects materials in the production process, and uses wood without obvious defects in the panels, door panels and furniture frames. In the same batch of furniture, the same part of the furniture, should choose materials of similar material nature. Because the shrinkage rate of the diameter cutting material is relatively small, when a large-area flat panel is spliced, a narrow-diameter cutting material should be selected as much as possible.
3. Manufacturers need to optimize the structure of furniture and reduce the occurrence of unreasonable parts. When splicing solid wood panels, it must be treated, usually with a wooden strip on the other side of the board. If the structure permits, it should be made into a five-in-one plate.
4. The company should do a good job in process management, reduce the stacking time of semi-finished products, and carry out finishing treatment as soon as possible. The blank of the product after the completion of the front section of the wood product should be arranged as soon as possible. If the painting time is long, it is best to finish the coating of the closed primer to form a protective film between the furniture and the atmosphere to prevent the component from being Hygroscopic expansion when not closed.
5. In the process of painting, for the furniture manufacturing enterprises, for some independent door panels and panels, the thickness of the fuel injection on both sides should be as close as possible to avoid deformation and bending caused by different forces on both sides.
Cracking and deformation are common problems in the industry and a major pain point for furniture manufacturers. Although this situation cannot be completely eliminated due to the natural characteristics of wood, furniture manufacturers can master the relevant knowledge and deal with materials, structures and processes, so that the probability of it can be minimized.
