Why is partnering with WoodWay Expert and using finger-jointed walnut in your production a beneficial solution for American companies? Our partners cite the following advantages of finger-jointed walnut panels:

• Durability. A key advantage of edge-glued panels made from finger-jointed lamellas is their ability to withstand significant operational loads without deformation. This is achieved through finger-jointing technology. The wood strips are glued together in a specific order, forming a monolithic structure. The glued construction ensures resistance to mechanical stress.
• Dimensional Stability. Walnut edge-glued panels are a material with predictable stability. The manufacturing technology minimizes the risk of warping and cracking. Lamellas of dried wood (8-10% moisture content) are arranged during gluing so that the alternating grain direction in adjacent strips compensates for residual internal stresses.
• Efficient Use of Raw Materials. Finger-jointed panels are made from lamellas of various lengths. The efficient use of wood reduces raw material costs. Waste reduction leads to a lower cost for the finished product. This allows businesses to offer more competitive prices without compromising on quality.
• Ease of Machining. Walnut edge-glued panels are delivered already calibrated and sanded, meaning the material is ready for further processing. The surface is easy to stain, varnish, and machine in all ways: routing, sanding, and cutting. Manufacturers can adapt the product to various design requirements.
• Eco-Friendliness. The glued panels are made from wood and certified D3/D4 moisture-resistant adhesive. The product meets environmental quality standards and principles of sustainable development.

This stable material does not deform over time, which significantly reduces the defect rate and simplifies production processes, ensuring predictable product quality. Edge-glued panels are a cost-effective and reliable solution for mass production.

The Manufacturing Technology of Finger-Jointed Walnut Panels

An edge-glued panel is an engineered product that combines the natural beauty of wood with enhanced stability and strength. The creation of glued wood panels involves several stages. To understand the material’s performance characteristics, it is important to understand each step of the production process.

Wood Preparation

The production cycle begins with the selection of kiln-dried boards. Joinery-quality wood with a moisture level of 8-10% is the foundation of high-quality panels. Proper drying removes internal stresses from the wood and minimizes the solid wood’s tendency to warp, cup, or crack.

Cutting Boards and Sorting Lamellas

Walnut boards are cut into wooden strips—lamellas of specific sizes. After sawing, the segments are checked for grade compliance. Lamellas with defects are rejected or sent for additional processing, where knots, cracks, and wormholes are cut out. After sorting, the selected segments undergo four-sided calibration. Lamellas of various lengths are used for panel production, which significantly optimizes raw material consumption and reduces waste.

Milling Finger Joints and Edge-Gluing Lamellas

A special serrated profile—the finger joint—is milled on the ends of the strips. This joint provides the maximum bonding area and a secure connection between the parts. A moisture-resistant D3 or D4 class wood adhesive is evenly applied to the surface of the finger joints. The lamellas with the applied glue are then joined end-to-end under significant pressure. This process creates long segments. It is important to note that the finger joint is often stronger than the wood itself, which increases the overall reliability of the panel.

Assembling the Solid Panel

The finger-jointed lamellas are laid out into a panel according to specific rules. The segments are matched for shade and texture. The panel is assembled in the following sequence: the grain direction in adjacent segments must differ. This multi-directional structure creates a stress-compensating effect. Glue is evenly applied to the side surfaces of the strips, and then the segments are bonded under a press. By alternating lamellas with different textures and colors, a surface with a pattern resembling parquet or a checkerboard is formed.

Calibrating, Sanding, and Packaging

The glued panels are first calibrated to ensure precise dimensions and thickness, and then they are sanded. The result is a material that is ready for varnishing, staining, or oiling. Afterward, each walnut panel undergoes quality control. The finished panels are packaged in protective film for safe storage and transportation.

Why Professionals Choose Walnut Edge-Glued Panels Over Solid Wood

The choice of material is a key decision for every manufacturer. For centuries, solid wood was considered the standard of quality, but modern production technologies have offered the joinery market the edge-glued panel. In many aspects, this material made from glued wooden strips surpasses solid wood.

To understand the advantages of edge-glued panels, one must first understand the disadvantages of solid wood. As a natural material, solid wood is anisotropic. This means that its strength, hardness, and dimensional changes with fluctuations in humidity vary depending on the grain direction. The greatest shrinkage and swelling occur across the grain, while changes along the grain are minimal. In solid wood, all fibers are oriented in the same direction, so changes in humidity and temperature cause significant internal stress. Drying or swelling leads to undesirable deformations: cupping, twisting, and cracking.

The multi-directional structure and multi-stage production process solve the problem of anisotropy and its associated deformations. Let’s look in more detail at the technological advantages that ensure the stability and strength of walnut edge-glued panels.

Kiln-Drying of Wood

The process of creating a panel begins with the selection and cutting of dry walnut boards into lamellas. It is at the drying stage that most of the internal stresses that cause deformation in solid wood are removed. This means the foundation of the panel is uniformly dried segments with an optimal moisture content of 8-10%.

Multi-Directional Structure

The panel is formed according to specific rules. The wooden lamellas are arranged so that the fibers in adjacent segments are oriented in different directions. This “checkerboard” or “parquet” sequence allows one lamella to compensate for the potential deformation of its neighbor. As a result, a balance is achieved, and stresses within the panel mutually cancel each other out.

Finger-Jointing Technology

Finger-jointed lamellas are obtained by joining strips of various lengths using a finger joint—a serrated profile. Jointing the ends significantly increases the gluing area, which guarantees a reliable connection of the elements. The combination of stress compensation across the width (due to the alternation of strips) and along the length (due to numerous finger joints) makes the finger-jointed panel maximally stable. This is precisely why finger-jointed walnut surpasses solid wood.

Quality of Raw Materials

High-quality wood is used in the production of walnut edge-glued panels. Before gluing, large knots, cracks, and rot are cut out from the strips. The elimination of structural defects ensures the uniformity and durability of the finished edge-glued panel.

Reliability of Glue Joints

Moisture-resistant D3/D4 class wood adhesives are used for bonding the wood. The strength characteristics of the joints are not inferior to solid wood. Furthermore, thanks to the numerous glue lines, residual stresses are evenly distributed over the entire area of the panel, not concentrating in one point.

A finger-jointed walnut panel is not just “glued wood.” The material has predictable behavior, which is critically important for mass production.

European (English) Walnut Wood: Key Parameters

European Walnut (Juglans regia), also known as English Walnut, is a valuable hardwood species common in the temperate latitudes of Europe, Asia, and America.
