摘　　要：汽车转向电机壳体是一种薄壁铸件,是关系到汽车安全运行的结构件,因此对他的内在质量和加工、安装的精度要求都非常高.为了实现该电机壳体的批量生产,从模具的设计和加工、压铸工艺、铸件加工工艺及检测方法等进行了技术改进,成功实现了壳体的大批量生产.Automotive steering dynamo shell is a thin-walled casting, and is a component that is of vital importance to safe motion of automobile. Consequently, dynamo shell is required to possess both very high internal quality and accuracies of machining and installing. In order to reach batch production of the dynamo shell, improvements in design and machining of mold, die casting process, and machining and examination of the castings were performed, with the result that mass production of the dynamo shell was successfully attained.
