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.

在压缩模塑艺中，增加预热、预压，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.

回弹后密度的影主要为压力，其次为加压时间和压缩次数，而含水率对板坯回弹密度的影不明显。
