What should the heads of departments such as title molding and stone setting pay attention to?

Supervisors of title molding, stone setting and other departments should pay attention to the safety of tools and the disposal of waste liquid. For example, when using a gun, be careful not to point it at people, check pipeline gas, and potassium cyanide and hydrogen peroxide cannot be stored together. Mold making refers to the process of carefully repairing jewelry blanks. Gold frying refers to the process of decontaminating and brightening metal jewelry after molding. Both processes are essential for processing diamond jewelry. Stone setting and post-processing: After gold blasting, the stone setting, polishing and cleaning are the same as the handmade process.
