The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The number of layers is generally odd, and a few are even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small.
