Plywood is a type of sheet material made by gluing together multiple layers of veneers, typically consisting of an odd number of layers with the grain direction of adjacent layers perpendicular to each other. This type of board is formed by aligning the glued veneers along the grain direction to create a blank, which is then pressed together under heated or unheated conditions. Common types of plywood include three-ply and five-ply boards, with an odd number of layers, though a few may have an even number.
Plywood has a wide range of applications, not only in furniture manufacturing but also in aircraft, ships, trains, automobiles, construction, and packaging. Due to its good structural strength and high stability, plywood is also widely used in decoration and finishing, such as as the baseboard for decorative panels and the back panel for panel furniture.
In the manufacturing process, plywood is produced by rotary-cutting or slicing wood into veneers, which are then processed through gluing, assembly, and hot pressing. Its physical and mechanical properties show minimal difference in the longitudinal and transverse directions, making it excellent in various applications.
