3. Cryogenic treatment of metal materials.

Cryogenic treatment of metal materials with liquid nitrogen stored in liquid nitrogen tanks can change the metallographic structure of metal materials and significantly improve the hardness, strength and wear resistance of metal materials.

4. Cryogenic assembly of precision parts.

The precision parts are assembled after cryogenic treatment of liquid nitrogen to improve the assembly quality of the parts, thereby improving the overall performance of the equipment or instrument.

5. Refrigeration and freezing in the medical and health industry, and refrigeration for medical operations.
