The manufacturing process of OSB (Oriented Strand Board) mainly includes the following steps:
1. Raw material preparation: High-quality fast-growing timber is selected as the raw material. It is then cut and crushed to form wood chips or strands.
2. Oriented layering: The wood chips or strands are laid out in specific directions and angles to form a multi-layered structure. This layering method results in excellent strength and stability of the board.
3. Pre-pressing treatment: The layered boards undergo pre-pressing treatment to improve their density and stability.
4. Hot pressing and molding: The pre-pressed boards are placed in a hot press machine and molded under high temperature and pressure. This step is a crucial part of OSB manufacturing, determining the physical properties and appearance quality of the board.
5. Post-processing: After hot pressing and molding, the boards undergo post-processing, such as sanding and cutting, to meet the requirements of different applications.
