6. After the use of vinyl chloride filled bed casting sag, it must wait for its drying to be polished. After each grinding, the surface grinding and dust shall be cleaned thoroughly.

7. The water grinding technology is used for grinding, so as to prevent the surface rust of the machine casting process, it is necessary to use anti-rust water to polish it.

8. After polishing, if there is a metal exposed phenomenon, it is necessary to brush the supporting primer.
