一、概述 利用金属材料的超塑性能来制造模具,是一种快速而又简便的制模方法。许多中小工厂先后采用了该项工艺。 从目前应用情况来看,大多采用一个工件设计制造一套相应的辅助工装,并且是机内成形,机外人工卸模,不仅工作环境差, First, an overview The use of superplastic metal material to manufacture mold, is a fast and easy method of modeling. Many small and medium-sized factories have adopted the process. From the current application situation, most of the use of a workpiece design and manufacture of a corresponding auxiliary tooling, and is the machine forming, machine unloading manual unloading, not only poor working environment,
