How is the Curved Wooden Table and Chair Made?

Wood bending is the process of softening wood, bending it into the required curve shape under the action of bending moment, and drying it to shape. Wood cannot be softened by heat, but it can be softened by steam.

Ⅰ. Choose suitable wood for wooden tables & chairs

1. Bending performance

The bending properties of different species of wood for wooden tables and chairs vary greatly, even if the same tree species has different bending properties in different parts of the same tree. According to the production practice, the tree species with better bending properties include elm, oak, ash, beech, birch and other wood for broad-leaved wood, and pine and spruce are better for soft-leaved wood.

2. Moisture content

The moisture content of the wool has a great influence on the bending quality and processing cost; if the moisture content is too low, the wool is easy to break; Prolong the setting and drying time of bent parts; square materials with a moisture content of 10% to 15% can be bent directly without softening treatment, and the moisture content of bent wool after softening treatment is preferably in the range of 25% to 30%.

Ⅱ. Process flow of wooden tables and chairs

Wool selection and processing→softening treatment→bending→drying and shaping→processing of bent parts.

1. Round hot bending

Driven by single-axis rollers, it is used for the manufacture of closed-circle wooden products such as seat frames and armrests.

2. Open hot bending

OEM wooden dining chair and tables repeatedly press the steam-heated wood on the mold, and finally the contour is close to the surface of the mold to form a thermal curvature, which is suitable for forming open curved shapes, such as the backrest of the seat.

3. Precautions

To bend wood, you need steam. The most typical way is to adjust the part you need to bend in the steam box. But this has 3 disadvantages: the size of the steam box must be suitable for the size of the curved part; when the curved part is transferred from the box to the mold, it will start to cool and lose its elasticity; the steam box takes up a large area.

All the materials of the tables and chairs made by wooden dining table supplier are solid wood, including the tabletop and side panels, etc. are made of pure solid wood, and no other forms of wood-based panels are used. Pure solid wood tables and chairs have high requirements on craftsmanship and materials. The requirements for material selection, drying, finger-joining and patchwork of solid wood are very strict. If any process is not strictly controlled, there will be cracks and loose joints in small cases, and the whole set of furniture will be deformed and unusable in large cases. The other is imitation solid wood tables and chairs. The so-called imitation solid wood tables and chairs are solid wood tables and chairs in appearance. The natural texture, feel and color of the wood are exactly the same as solid wood tables and chairs, but in fact they are tables and chairs mixed with solid wood and wood-based panels, that is, the top, bottom, and Particleboard or MDF fiberboard veneered with veneer for parts such as shelves.
