有报道称,采用铝质注塑模的加工循环周期要比P20钢制模具的加工循环周期更短,其中的一种解释是:铝材的热传导系数较高,接触到塑料熔体后,可更快地传导热量至模具表面,由此可实现更快速的充模过程,并且靠近模壁位置上塑料部件的硬化程度很低。持这一观点的论文最初发 It has been reported that the use of aluminum injection mold cycle than P20 steel mold machining cycle shorter, one of the explanations is: aluminum heat transfer coefficient is higher, after contact with the plastic melt can be more The heat is quickly transferred to the mold surface, whereby a faster filling process can be achieved and the plastic part is less rigid near the mold wall. Papers holding this view were first published
