Solid wood curved board splicing process: Solving pain Points and Fushen GW-1501 curved Board Adhesive Solution

Solid wood curved boards, with their natural wood grain texture and smooth arc-shaped lines, are widely used in furniture and home products such as chair backrests, table edges, and cabinet curved surfaces, becoming a key process for enhancing the appearance and comfort of products.

However, during the pressing process of solid wood curved boards, it is easily affected by the characteristics of the wood and the process conditions, and there are many hidden difficulties. As the "core link" in the panel assembly process, whether the glue is properly selected directly determines the quality of the final product. Fushen provides you with a detailed solution for the solid wood curved board splicing process.

I. Core Difficulties in the Pressing of Solid Wood Curved Boards

Uneven stress leads to cracking: When wood grain differences cause bending, the force on the joints is weak, and insufficient glue strength makes it prone to delamination and scrapping.

Moisture content causing deformation: Fluctuations in the moisture content of wood or the release of water from glue can easily lead to dry shrinkage and wet expansion of the finished product, as well as arc-shaped rebound.

The curing speed is difficult to adapt: If it cures too quickly, it is prone to false adhesion and bubbling; if it cures too slowly, it will occupy equipment and reduce production efficiency.

Environmental compliance risks: The glue contains harmful substances such as formaldehyde, which can easily lead to unqualified tests and consumer complaints.

Ii. Selection Criteria for Glue for Solid Wood Curved Boards

High bonding strength: ≥10MPa, wood failure rate ≥90%, resistant to bending stress;

Water resistance and shrinkage resistance: Meets the Class II water resistance standard of GB/T 14732-2017, with a curing shrinkage rate of ≤1%.

Controllable curing: Cold pressing is suitable for 15-30 minutes of open time and 4-6 hours of curing, while hot pressing is suitable for 30-60 minutes of curing at 60-80℃.

Environmental protection compliance: Formaldehyde emission ≤0.184mg/m³ (E1 grade), no volatile organic compounds;

Good wettability: Easy to apply, no sagging, compatible with both manual and machine gluing.

Iii. Advantages of Fushen GW-1501 Bending Board Adhesive

Strong bonding and crack resistance: Modified polyvinyl alcohol formula, bonding strength ≥12MPa, wood failure rate ≥95%, arc-shaped inflection points are not prone to cracking.

Water resistance and shape stability: D4 waterproof grade, passed the Japanese boiling water peel test, with a curing shrinkage rate of only 0.8%, avoiding arc-shaped rebound.

Flexible curing: Cold pressing opens in 20-25 minutes and cures in 5 hours; hot pressing cures in 35 minutes at 80℃, suitable for multiple processes.

Super environmentally friendly: Formaldehyde emission ≤0.08mg/m³ (better than E0 grade), VOC≤50g/L, no pungent smell.

4. Fushen Woodworking Adhesive: 20 years of focus on woodworking adhesives, with quality guaranteed by strength

The reliable performance of Fushen GW-1501 bending plate adhesive stems from the profound technical accumulation of Guangdong Fushen Chemical Co., Ltd. behind it. Established in 2005, Fushen is a "veteran force" in the domestic field of woodworking adhesives. It has always been committed to the mission of "enabling every wood products factory to use good adhesives" and has built a complete integrated system of "R&D - production - sales".

Profound technical accumulation: For 20 years, we have been focusing on the research and development of environmentally friendly and high-performance woodworking adhesives. The core members of our team have over 15 years of industry experience. The performance of our products has surpassed the international professional level. Especially in the specialized fields of wood veneer adhesives, panel gluing adhesives, and curved board adhesives, our technical strength has been highly recognized, and we are hailed as the "Expert of wood veneer adhesives in China".

Full product line coverage: In addition to bending board glue, Fushen's product line also includes water-based environmentally friendly single-component glue, wood veneer glue, panel joining glue, assembly glue, pressing glue, etc. It can provide a "one-stop glue solution" for wood product factories, meeting the needs of different processes (manual veneering, mechanical panel joining, arc-shaped bending and pressing).

Strict quality control: The production base is equipped with advanced testing equipment. From the raw materials entering the factory to the finished products leaving the warehouse, each batch of products undergoes triple tests of "bonding strength, water resistance and environmental protection" to ensure that 100% of the products leaving the factory are qualified, providing a strong guarantee for the enterprise's production.
