The Process of Wood Transformation into Plywood

Overview of the Manufacturing Process

• The process begins with the perpendicular layering of glued veneers, using roller gluing machines that apply 200 to 300 grams per square meter, regardless of board thickness.

• After initial assembly, the layers are placed in hot plate presses where pressure, temperature, and time cure the adhesive—urea for interior use and phenolic for exterior applications.

• The final touches involve squaring the boards to achieve precise dimensions while eliminating excess material from previous cutting processes.

Quality Control and Classification

• Plywood classification is based on species composition, veneer quality (face and back), and adhesive type used; structural plywood undergoes rigorous quality control to ensure physical and mechanical properties meet standards.

• Once processed, wood transitions from raw material to an industrial product. This marks a significant transformation but also initiates another phase where it may be used in various applications like doors or recreational boats.
