Abstract：Through thorough studies over existing technologies related to continuous presses for wood-based panels， including on-line precise control， hydraulic-electro high-frequency-response thickness and press control， rolling chain blanket manufacture， self-adaptive load synchronization and surface-adaptive control， this research solves core manufacture issues of continuous presses system such as the adaptability of input angle and the synchronization of rolling chain blanket. Using new technologies， continuous press system is self-adaptive to variant board thickness， andprecise manufacturing issues， including core parts high precision manufacturing， temperature tolerance， abrasion resistance， compression resistance， etc. are solved in the meanwhile. Monitor and control in millisecond-timescale over system key points are achieved through on-line precise control technologies， and high speed response of key hydraulic parts is guaranteed. This research breaks through the blockade of patents on continuous presses for wood-based materials controlled by foreign companies， and forms a series of technologies with independent intellectual property rights relating to continuous presses， including electronic PLC automatic control system， high-frequency-response hydraulic servo control system and etc. A prototype of continuous press system with capacity of 150，000 m3 of wood-based panels per year has been trialed and finalized. The new technologies can significantly improve the quality of final product with reduced consumptions of power and raw materials. The yield ratio rises by 40% and the production efficiency improves by 25%.
