- 摘要:
- 为了生产出12VZJH机体铸件,并解决油道管弯曲的关键技术问题,通过设计合理的铸造工艺方案,以及"预提芯组芯"操作方法,解决难点。最终生产出合格产品。并为同类产品生产提供借鉴。In order to produce 12 V ZJH body casting and solve the key technical problems of oil duct bending, the difficulties were solved by designing a reasonable casting process scheme and the operation method of "withdraws core assembly core". Finally produces the qualified product, and provides the reference for the similar product production.
