Veneers from high-quality logs are mechanically dried and they undergo a stress-relieving process, which is assembled in such a way, to form a balanced construction. High quality fortified synthetic resins are used for gluing the veneers. Glue line is poisoned by special formulations of chemicals to make Ogaan plywood safe against borers. It is hot pressed under proper temperature and more than then 16Kg/cm2 specific pressure. Conditioning is done after pressing, followed by preservative treatment.
