In the compression moulding technology, preheat and prepressing procedures are added to improve the flowability of the bond and physical and mechanical properties of the product.

在压缩模塑工，加预热、预压工序，提高粘合剂的流动性和产品的理机械性能。

The main factor of spring back density is prepressing pressure, next are compression time and compression number of times.The effect of moisture content was not significant.

回弹后密度的影响因子主要压力，加压时间和压缩数，而含水率对板坯回弹密度的影响不明显。
