超塑成型工艺降低了铝部件的加工成本据美国ＮＡＳＡ兰利研究中心报道，该中心采用超塑成型（ＳＰＦ）工艺制造了用于航天飞机低温推进剂外贮箱上的铝加强肋部件，从而替代了传统的机加工方法。过去，加强助的制造首先是将铝板加工成纵向Ｔ型梁，然后再焊接在一起。这一过... Superplastic molding process to reduce the cost of processing aluminum parts According to NASA Langley Research Center reported that the center uses superplastic forming (SPF) process for the manufacture of low-temperature space shuttle cryogenic propellant aluminum tank rib parts to Replaces the traditional machining methods. In the past, reinforced manufacturing began with the processing of aluminum plates into longitudinal T-beams that were then welded together. This one ...
