How Veneer is made?

Wood veneer is a popular material used in various industries like veneer plant, plywood mill, funirture factory, including furniture manufacturing and interior design. It is a thin slice of wood that is typically glued onto a substrate to enhance the appearance of a surface. If you'want to know how wood veneer is produced, this article will provide you with an overview of the production steps involved.

1. Log Selection:

The first step in producing wood veneer is selecting the right logs. High-quality logs with straight grain patterns and minimal defects are preferred. Logs that are suitable for veneer production are typically harvested from trees that have reached maturity. 

From Different countries, the people will choose suitable wood according to their local resource and veneer demands, For example, some people use beech wood or birch wood, some country use pine wood and eucaltptus wood, some use poplar wood or others

2. Peeling:

Once the logs are selected, they are prepared for peeling. Peeling is the process of removing thin layers of wood from the logs to create veneer sheets. The logs are rotated against a sharp blade, and a continuous sheet of wood is peeled off. This process requires precision and expertise to ensure consistent thickness and quality.

Usually for the peeler, it includes two types, the Spindleless and Spindle, their function for peeling wood and producing veneer sheets. just they are suitable for different wood diameter. For example, if your wood diameter less than 600mm, then choose the spindleless peeling machine will be a good choice, if your wood diameter is bigger, like some our Africa clients, their wood very big. like 1000mm, 1300mm diameter, thus the Spindle peeling machine will be a good choice

3. Cutting:

After the logs are peeled, the veneer sheets are cut into required sizes. This step is crucial to ensure that the veneer sheets can be easily handled and processed further. The sheets are typically cut into standard dimensions, such as 4 feet by 8 feet, which is commonly used in the industry.

Some clients choose the seperate veneer clipper/veneer guillotine, which connects with veneer peeling machine, for cutting veneers. Also most clients choose the veneer peeling machine includes veneer cutting knife, so it will peel and cut at the same time.

4. Sorting and Grading:

Once the veneer sheets are cut, they are sorted and graded based on their quality. This step involves inspecting the veneer for defects, such as knots, splits, or discoloration. Veneer sheets with minimal defects are graded higher and are often used for premium applications, while those with more defects may be used for lower-grade products.

For automatic sorting veneer sheets, usually it need the Vacuum veneer stacking machine, thats its function, also the last step of the complete veneer production line. With this stacker, it can improve your production capacity, and save two workers cost.

5. Drying:

After sorting and grading, the veneer sheets undergo a drying process. This is done to reduce the moisture content of the wood veneer, making it more stable and less prone to warping or shrinking. The sheets are typically placed in a controlled environment, such as a kiln, where temperature and humidity levels are carefully regulated.

Because the veneer comes out from the wood, wood has water content, so the veneer's humidity also high and different. Veneer is the material for wooden products, like plywood, lvl, wooden chair or others, so such humidity is not suitable for making end product. thats why drying veneer humidity. So for this step, you need the veneer dryer, which includes three types, roller dryer, mesh dryer and press dryer. 

According to your drying capacity, veneer size and thickness, and species, and other factors, choose the suitable dryer machine.

6. Gluing:

Once the veneer sheets are dry, they are ready to be glued onto a substrate. The substrate can be a variety of materials, such as plywood or particleboard. The sheets are carefully aligned and bonded to the substrate using specialized adhesives. This process ensures that the veneer is securely attached and will not peel off over time.

7. Finishing:

After the veneer sheets are glued onto the substrate, they undergo a finishing process. This involves sanding the surface to achieve a smooth and even finish. The veneer may also be stained or coated with protective finishes to enhance its appearance and durability.

In conclusion, the production of wood veneer involves several steps, including log selection, peeling, cutting, sorting and grading, drying, gluing, and finishing. Each step requires skill and precision to produce high-quality veneer sheets that are used in various applications. So, the next time you admire the beauty of wood veneer, you'll have a better understanding of the intricate process behind its production.
