Finger Joint Wood – The Ideal Solution for High-Quality Wood Exports

What is Finger Joint Wood?

Finger joint wood, also known as finger joint board, is an engineered wood product created by bonding multiple small wood strips using specialized adhesives. Once joined, these pieces are compressed under standardized temperature and pressure, forming durable, structurally stable wooden panels.

Designed with interlocking finger joints, this type of wood ensures a firm connection, effectively minimizing warping, cracking, and extending the product’s lifespan. Many people mistake finger joint wood for box joints, but these are two different techniques. Box joints are primarily used in wooden frame construction and box manufacturing.

The Evolution & Growth of Finger Joint Wood

Finger joint wood has been around for many years, but it only experienced significant industrial growth in the 1970s, thanks to technological advancements in manufacturing. Today, Europe is the leading producer of finger joint wood, followed by North America, South America, and Asia.

Vietnam is emerging as a major supplier of finger joint wood, benefiting from abundant raw materials, competitive pricing, and internationally recognized quality standards.

Composition of Finger Joint Wood

Common Wood Materials Used:

✔ Acacia (tràm): High strength, excellent durability
✔ Rubberwood: Cost-effective and eco-friendly
✔ Pine, cedar, and oak: Popular choices for premium furniture production

Types of Adhesives Used:

✔ Urea Formaldehyde (UF): High adhesion, ideal for interior use
✔ Phenol Formaldehyde (PF): Excellent water resistance, suitable for outdoor applications
✔ Polyvinyl Acetate (PVAc): Safe for health, environmentally friendly

Finger Joint Wood Manufacturing Process

🔹 Step 1: Wood Drying

• Removes resin, sap, and excess moisture to prevent mold and termite damage.
• Maintains moisture content at 10% ± 2%, meeting export quality standards.

🔹 Step 2: Cutting & Finger Joint Profiling

• Standard dimensions:
  • Width: 600 mm
  • Length: 2400 mm
  • Thickness: 38 mm
• Two types of finger joints:
  • Vertical joints (exposed joints): Increases structural strength but exposes joint lines.
  • Horizontal joints (concealed joints): Provides a seamless and more visually appealing finish.

🔹 Step 3: Planing & Surface Preparation

• The wood strips are precisely planed, creating a smooth and even surface for jointing.

🔹 Step 4: Adhesive Application & Jointing

• Uses Koyobon D4 adhesive from Japan, ensuring water resistance and long-lasting adhesion.
• Wood pieces are compressed with hydraulic presses, forming solid, high-quality wood panels tailored to customer specifications.

🔹 Step 5: Sanding & Surface Finishing

• The wood panels are sanded on both sides to achieve a smooth finish, ready for painting or veneer application.

🔹 Step 6: Quality Inspection

• Products undergo strict quality control to ensure compliance with export standards for the USA, Australia, and the EU before packaging.

Finger Joint Wood Classification by Quality

🏆 Grade AB – Export Standard
✔ Flawless top surface, 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 defects on both sides, suitable for flooring, doors, wooden frames, and outdoor furniture.

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