Finger Joint Wood – A Superior Choice for High-Quality Exports

Understanding Finger Joint Wood

Finger joint wood, also referred to as finger joint board, is an engineered wood product crafted by bonding small natural wood segments with specialized adhesives. These pieces are then compressed under controlled pressure and temperature, forming large, durable wood panels with excellent structural strength.

Featuring interlocking finger joints, this wood type offers tight connectivity, effectively reducing warping and cracking while significantly enhancing durability. While it is sometimes mistaken for box joints, the two are distinct—box joints are primarily utilized in wooden box construction and structural frameworks.

The Development of Finger Joint Wood

Although finger joint wood has been in use for a long time, its industrial production gained momentum in the 1970s, thanks to technological advancements. Today, Europe leads global production, followed by North America, South America, and Asia.

Vietnam is rapidly becoming a key player in the industry, recognized for its affordable production costs and high-quality standards.

Composition of Finger Joint Wood

Commonly Used Wood Types:

✔ Acacia (tràm) – Highly durable with strong load-bearing capacity
✔ Rubberwood – Economical and environmentally friendly
✔ Pine, cedar, and oak – Preferred for premium furniture manufacturing

Types of Adhesives Used:

✔ Urea Formaldehyde (UF) – High bonding strength, ideal for indoor applications
✔ Phenol Formaldehyde (PF) – Water-resistant, suitable for outdoor use
✔ Polyvinyl Acetate (PVAc) – Safe for health and environmentally sustainable

Production Process of Finger Joint Wood

🔹 Step 1: Wood Drying

• Eliminates resin, sap, and moisture to prevent mold and termite damage.
• Maintains moisture content at 10% ± 2%, in compliance with export regulations.

🔹 Step 2: Cutting & Finger Joint Profiling

• Standard dimensions:
  • Width: 900 mm
  • Length: 2400 mm
  • Thickness: 36 mm
• Two common finger joint types:
  • Vertical joints (exposed joints): Improve structural strength but leave visible seams.
  • Horizontal joints (concealed joints): Deliver a smooth and aesthetically pleasing finish.

🔹 Step 3: Planing & Surface Preparation

• Wood surfaces are finely planed to ensure evenness and readiness for assembly.

🔹 Step 4: Adhesive Application & Jointing

• High-quality Koyobon D4 adhesive from Japan is used for water resistance and long-lasting adhesion.
• Wood pieces are compressed with hydraulic presses, forming solid wood panels customized to client specifications.

🔹 Step 5: Sanding & Surface Finishing

• Panels are sanded on both sides, creating a smooth finish, ready for painting or veneer application.

🔹 Step 6: Quality Inspection

• The final products undergo rigorous testing to meet export standards for the USA, Australia, and the EU before packaging.

Finger Joint Wood Quality Classification

🏆 Grade AB – Premium Export Quality
✔ Flawless top surface with minor black spots (≤ 10mm) on the bottom.

⭐ Grade AC-AD – Medium Quality
✔ Smooth top surface, bottom surface with larger imperfections (> 10mm).

🔨 Grade BC – Structural Applications
✔ Minor imperfections on both sides, ideal for flooring, doors, wooden frames, and outdoor furniture.

🏗 Grade CD – Industrial Use
✔ More visible defects, best suited for subflooring and veneer lamination.
