| Abstract: | The production of a typical thin-walled aluminum castings with gypsum mold casting combining with pouring in vacuum pouring and solidification under pressure was performed.By controlling the gypsum mold making process and reasonable additive use,adopting open-gating system with multi-point arrangement,and optimized pouring parameters,such as pouring time,pouring position,the mold temperature and pouring temperature,the thin-walled aluminum castings were produced successfully,which met the requirement of the specification. |
