ZnAl22合金是一种新的超塑性制模材料,用热挤压方法制作模具型腔。适用于机械加工困难和冷挤压工艺无法成型的型腔模具制造。实践证明,对多型腔模具用同一型芯挤压能达到形状一致
ZnAl22 alloy is a new superplastic molding material, the use of hot extrusion mold cavity. For machining difficult and cold extrusion process can not be formed cavity mold manufacturing. Practice has proved that the same type of multi-cavity mold extrusion can achieve the same shape
