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，提高粘合剂性和产品理机械性能。

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.

密度影响因子主要为压力，其次为加压时间和压缩次数，而含水率对板坯密度影响不明显。
