Introduction to the production process of Russian birch-plywood

Russia is rich in birch resources and is the country that produces the most birch plywood. Birch plywood has stable performance, high strength, and beautiful appearance and color. It is one of the most popular plywood in the world. The Russian birch plywood industry is now very mature, with a special product standard GOST 3916.1-96 and a complete set of production and quality inspection processes. This article will elaborate in detail for the reference of consumers.

The company has an annual production capacity of 100,000 cubic meters of birch plywood, producing 7 grades of B/BB, BB/BB, BB/CP, BB/C, CP/CP, CP/C, and C/C. The product format mainly includes 8 x 4 and 5 x 10, mainly with phenolic glue for outdoor use. The factory is located in Nizhny Novgorod, Russia, which is one of the regions with the most abundant birch reserves in Russia. The quality of the birch produced is very high. The density of birch plywood in this area can reach more than 700kg/m3, and the birch plywood produced in different regions The density is 640kg/m3-700kg/m3.

The process of how the birch-plywood was made.

1. Forest

Large-scale birch plywood factories generally have their own birch forests. Our company’s forests are FSC-certified sustainable forests, and we can provide FSC-certified birch plywood.

2. Log harvesting

Large-scale factories only harvest birch trees that are over 30 years old to ensure that the wood is compact. However, some domestically imported birch logs do not meet the age requirements, and the plywood produced is not dense enough.

3. Log cooking

After Russian birch logs are transported to the factory, they first need to be peeled and steamed to ensure that the wood is softened and at the same time release the internal stress of the wood. In this way, the veneer produced by rotary cutting is smooth and flat, which can significantly improve the bonding strength and surface smoothness of the plywood. There is no steaming process in the plywood factory. The veneer that is peeled has large burrs, is uneven, and has a large thickness deviation. There is a risk of warping and deformation of the board as a whole during storage or prolonged use.

4. Veneer cutting

Most of the large-scale plywood factories are equipped with large-scale rotary cutters with card shafts from Raute, Finland. Raute rotary cutters are famous all over the world for their high quality and high precision. Cutting machine can not be compared, the company rotary cut 1.4mm veneer for plywood production.

5. Veneer drying


The drum type veneer dryer is used to dry one by one, which can ensure that the moisture content of the veneer is uniform. At the same time, the dried veneer is flat and has little damage. method, and then use a multi-layer hot press to dry. This drying method cannot ensure that the moisture content of the veneer is uniform. At the same time, the veneer is easy to tear and deform. The plywood made of such a veneer is easy to hollow out and open glue. , deformation.

6. Sorting and repairing of veneer

The dried veneers are sorted out to B, BB, CP, and C grades according to the standard requirements, and the veneers that do not meet the requirements are repaired with a veneer repair machine.

7. Veneer gluing and billet assembly

The use of high-performance phenolic resin produced by Dynea in Tier, Finland, has stable performance and high solid content, ensuring that the birch plywood produced has excellent durability and water resistance. The cross-structure billet is adopted to ensure the flatness of the board to the greatest extent.

8. Cold pressing and hot pressing

Automatically controlled hot and cold pressing equipment is used to ensure that the glue is fully cured.

9. Sawing

High-precision WEILIG and other sawing equipment are used to ensure that the tolerances in length and width are within a reasonable range.

10. Sanding

STEINEMANN high-precision sanding machine made in Switzerland is used. As a world-renowned sanding machine brand, Stanleymont sanding machine can effectively guarantee sanding accuracy and sanding quality.

11. Sorting, inspection and packing

After the formed plywood is sorted, the thickness, length, width, moisture content, surface quality and other items are measured, and the products that do not meet the requirements are downgraded or unqualified. Each qualified product will have inspection on the side of each board. Covered with the company inspection stamp, then packaged and labeled.


The entire production process is inspected by corresponding quality inspectors.

At the same time, the laboratory is equipped with various testing equipment, which can test the mechanical strength, bonding strength, moisture content, formaldehyde release and other technical indicators of the product according to the company’s inspection process to ensure that the products produced Stable quality and consistent performance.

The Russian factory has strict requirements in terms of raw materials, equipment, quality control, personal safety, and environmental protection. The sources of raw materials used are legal. Highly environmentally friendly and healthy, when using Russian birch plywood, it will bring a full of Nordic style and the taste of nature!
