When the structure of the Surface treatment of hot pressing grouting mold is determined, it is also necessary to properly treat the surface. Different treatment methods can be used at the time of surface treatment. For example, the electric fire pattern refers to the pattern of different roughness formed on the surface of the cavity by electro-erosion machine tool, and the surface of the mold is fogged after discharge.
Another common treatment process is called sandblasting. Different types of sandblasting can be selected according to different Surface treatment of hot pressing grouting molds. The sprayed glass sand can make the surface of the mold bright and not easy to damage the mold. Spraying gold steel sand can make the surface of the mold foggy and have sand patterns. Spraying mixed sand can make the surface of the mold foggy and dull.
The role of sand blasting for surface treatment of hot pressing grouting molds mainly includes the following points: 1. It can meet the surface grain requirements of the product; 2. After the mold is produced for a period of time, the surface will adhere to a layer of low molecular substances, which will be sandblasted. 3, low cost of sand blasting, easy to operate, and will not cause deformation of surface treatment of hot pressing grouting mold.
