A Comprehensive Analysis Of Sheet Metal Forming Processes: Manufacturing Methods From Wood To Composite Materials

2025-10-05

I. Wood-based Sheet Forming Processes Wood-based sheet forming mainly includes two mainstream technologies: fiberboard and particleboard. In the production of fiberboard, wood is first chipped and the fibers are separated. Then, adhesives and waterproofing agents are added. After high-temperature and high-pressure treatment, a sheet with a uniform structure is finally formed. Its performance depends on the quality of the fibers and the amount of adhesive used. For particleboard, wood is processed into particles, dried, and then glued. The particles are laid in a mold and formed, followed by hot pressing. The gluing process usually uses roller coating or spray gluing methods to ensure the bonding strength between the particles. The temperature and pressure in the hot pressing stage directly affect the density and stability of the sheet. CNC Press Brake II. Metal Sheet Forming Technologies The processing of metal sheets covers key steps such as rolling, stamping, and surface treatment. The rolling process is divided into hot rolling and cold rolling. In hot rolling, steel billets are treated at high temperatures and continuously rolled into steel sheets of the required thickness. It is highly efficient but produces sheets with a relatively rough surface. Cold rolling is carr...
