   The pressing cycle operates in stages, with the mat thickness being first compressed to around 1.5 times the finished board thickness, then compressed further in stages and held for a short period. This gives a board profile with zones of increased density, thus mechanical strength, near the two faces of the board and a less dense core. [9]
