薄壁铸件用石膏造型的实践

Practice of Gypsum Moulding on Thin-wafted Castings

叶轮和导轮是构成增压风扇部件的主要零件，通过“加压铸造法”和“易清理石膏型”两项工艺的实践，探讨解决薄壁铸铝件浇铸缺陷，取得较好的效果。

The impeller and the inducer are major constitutions of turbo-charged ventilator part. By compression casting and plaster mold, the defects of thin-walled aluminium castings are solved, and better effects are obtained.
