机电部“七五”重点科研项目,超塑性成型工艺技术应用研究,最近在太原三益公司完成并通过了鉴定。超塑性成型工艺技术研究,是利用大部分金属材料具有的超塑性,用气压和挤压在低能低压下加工模具型腔及机器零件的一种工艺手段。三益公司技术攻关,在一些加工难度较高的 Ministry of electromechanical “Seventh Five-Year” key scientific research projects, superplastic forming technology application research, recently in Taiyuan Sanyi completed and passed the appraisal. Superplastic forming technology research, is the use of most of the superplastic metal materials, with pressure and extrusion in the low-pressure low-pressure processing mold cavity and machine parts of a process. Sanyi technology companies, in some of the more difficult processing
