The Processing Flow Of Engineered Wood Panels Mainly Includes The Following Key Steps:

I. Raw Material Processing: Wood is cut into different unit shapes (such as veneer, wood shavings, and fibers). Generally, boards composed of larger units have higher mechanical properties, while smaller units help improve the uniformity and stability of the board.

II. Drying Treatment: Appropriate drying processes are used depending on the type of raw material, such as veneer drying, wood shavings drying, and fiber drying. Modern drying is mostly carried out under heat-preserving and continuous conditions. First, rapid heating removes most of the moisture, followed by a controlled-speed drying stage to ensure the moisture content meets the standard and avoids material damage.

III. Adhesive Application Process: The method of applying adhesive varies depending on the material: Plywood production often uses roller coating; Particleboard and fiberboard production mainly uses spray coating to achieve uniform mixing of the adhesive with the wood units.

IV. Forming and Hot Pressing: Laying out the wood: Wood shavings or fibers are laid out in an oriented or random manner to form single-layer, three-layer, or multi-layer structural boards. Oriented laying can improve the mechanical properties of the board in a specific direction.

Hot-press curing: In a hot press, the adhesive cures in the plywood through the combined effects of temperature, pressure, and time, forming a stable board. In plywood production, adjacent layers of wood with perpendicular grain are often joined to improve the board's dimensional stability and strength balance.

This series of processes, through meticulous control, achieves efficient utilization of wood resources and endows the engineered wood with stable physical properties and structural adaptability.
