随着社会主义建设的发展,不少大型精密零件亟待采用压铸。但由于缺乏大型设备,无法生产。成为当前压铸发展中的关键之一。为了探求在一般的设备条件下压铸大型零件的可能性,上海电表厂在1961年采用组合装置,在小功率普通油压机上,压铸成功投影面积(包括浇注系统)达 With the development of socialist construction, many large-scale precision parts urgently need to die-casting. However, due to the lack of large-scale equipment, can not produce. Become the current development of die-casting one of the keys. In order to explore the possibility of die-casting large parts under general equipment conditions, Shanghai Electric Meter Factory in 1961 with a combination of devices, in the small power of ordinary hydraulic machine, die-casting success projection area (including casting system)
