High Vacuum Die Casting 高真空压铸
In vacuum die casting process, the characteristic of cavity vacuum pressure curve was studied by theoretical calculation and experimental measurement by installing a vacuum pressure sensor inside an experimental die. The calculation was proved coincident with the experimental results.
