DescriptionHot pressing is an important step in the manufacture of wood composites. In the conventional pressing system, hot press output often acts as a constraint to increased production. Severe drying of the furnish (e.g., particles, flakes, or fibers) required by this process substantially increases the manufacturing cost and creates air-polluting emissions of volatile organic compounds, which are a main source of air pollution from the forest products industry. Wood composites made in the conventional process have high internal stress and low dimensional stability and strength. The development of a pressing technology to improve the process is limited by the release of vapor pressure during hot pressing. A perforated caul system may enlarge the area for the moisture to escape from the board mat during pressing, and thus, make possible high moisture content (MC) pressing.
