Electric porcelain insulator steel casting

Electric porcelain insulator steel casting is a common type of casting in sand casting. During casting, green sand is used to complete the sand mold shape through a horizontal automatic casting molding machine, and then a coated sand core is placed in the sand mold cavity to complete the internal structure shaping of the casting. This casting process is currently the most widely used and cost-effective method in steel casting. The material of this casting is ductile iron QT450-10. After casting the rough embryo, it is cleaned and polished, and then hot-dip galvanized with a zinc layer thickness of generally 86 microns;
