无模成形直接制造金属零件无模成形工艺没有工模具与工件之间的干扰，并且可以一次生产出整个零件，甚至还可带有活动部分，例如活动扳手就可以采用此法制造。由于没有工模具的干扰，因而零件几何形状很容易通过ＣＡＤ数据控制。生产的准备工作也较简单，故该法适用于单件... Die-Free Forming Directly Manufacturing Metal Parts Formless die-forming processes eliminate the interference between tooling and workpieces, and can produce entire parts at a time, even with moving parts such as spanners. Due to the absence of tool interference, the part geometry is easily controlled by CAD data. Production preparation is also relatively simple, so the law applies to a single ...
