Production technology of metal ice particles

The invention discloses a production technology of metal ice particles. The production technology comprises the steps of (1) cutting a metal sheet; (2) manufacturing metal components; (3) forming through holes in the side walls of a part of metal outer shells; (4) welding one metal component with through holes and another metal component without through holes, and manufacturing one hollow metal outer shell with an airtight cavity inside which communicates with the exterior through the through holes; (5) injecting a coolant through the through holes; (6) sealing the through holes through welding; and (7) carrying out grinding and polishing. Through the adoption of the technical scheme, the metal ice particles can be produced, reutilization is facilitated, and beverages are not diluted and do not go bad; the coolant is sealed in the metal outer shells, and the cooling effect of the metal ice particles is greatly improved; and production efficiency is high, manufacturing is facilitated, and grinding and polishin
