摘　　要：The general steam-injection pressing is mainly used for produce particleboards and medium density fiberboard. However, it is difficult to produce soft fiberboard with desired strength. However, the closing steam-injection pressing that based on the steam-injection pressing could. The wooden frame sealing up the slab could prevent the steam from emitting when the steam injected into the slab. The caloric released by steam condensation make the slab reach high temperature level for a short period. This method is very appropriate for making thick panels in theory, especially for the soft fiberboard. It makes a great leap forward on the hot pressing process that for wood-based panels. Moreover, it will be a meaningful technological breakthrough in developing new products and improving wood utilization.The general steam-injection pressing is mainly used for produce particleboards and medium density fiberboard.
