plywood veneer production line

Narrow plywood is a three-layer or multi-layered board that is cut into veneers by a wood veneer peeling machine or cut into thin wood and glued with adhesive. Usually, odd-numbered veneers are used and adjacent The fiber direction of the layer veneers is vertically glued to each other.

In a broad sense, a plywood is a multi-layer board material obtained by plywood veneer peeling machine a wooden section into a veneer or by cutting a veneer into a thin wood, and then bonding the adjacent veneers whose fibers are perpendicular to each other with an adhesive.

The surface is decorated with technical veneer or melamine paper, which is popular with the public because of its varied appearance and price. The main tree species are: eucalyptus, hawthorn, willow, poplar, elm and so on.


The picture above is plywood, the outermost front panel is called the panel, the back is the back panel, and the inner panel is the core panel. The core sheets are generally classified into 3 mm, 5 mm, 9 mm, 12 mm, 15 mm, and 18 mm. The plywood produced is generally 5-40 mm. Plywood has received many people's love because of its many changes in appearance and price advantages. The main tree species are: eucalyptus, hawthorn, willow, poplar, elm and so on.

What are the characteristics of plywood?

1. Plywood can save wood because of its high wood utilization.

2. Plywood is made up of multiple layers, so it is much cheaper than solid wood.

3. Plywood is also known as splint, plywood, nine PCT, multi-layer solid wood.

4. The number of layers of plywood is generally odd. Why is this? Odd layer principle: Since the structure of the plywood is that the fiber directions of the adjacent layers are perpendicular to each other and must conform to the principle of symmetry, the total number of layers must be an odd number. In addition, the maximum horizontal shear stress of the even-numbered plywood is applied to the adhesive layer instead of acting on the veneer, which easily breaks the adhesive layer and reduces the strength of the plywood.

Many people do not know the relationship between glulam and plywood. What is glulam? Glulam is also called glulam. It is a common wood construction material used in life.

Glued wood is a structural material made by cementing individual specifications of wood under certain conditions, such as glulam, curved glulam, glulam beam, Douglas fir glulam. Its characteristics make it often used to meet the aesthetic architectural and structural needs. In the production of glulam, the ends of the chips are bitten to each other and layered horizontally. The lamination method can effectively utilize high-strength but small-sized wood to make large structural parts of various shapes and sizes. It can be used to make long-span curved beams and is widely used in the manufacture of stadiums and large public clubs.
