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.

在压缩模塑工艺中，增加预热、预压工序，提高粘合剂的流产品的理机械。

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.

弹后密度的影响因子主要为压力，其次为加压时间压缩次数，而含水率对板坯弹密度的影响不明显。
