2、 Application Cases

（1） Deep cooling treatment of blade after quenching

In a certain tool manufacturing enterprise, the Xinzhi Afs low-temperature freezer is widely used in the freezing and quenching process of razor blades, art blades, and industrial blades. After deep cryogenic treatment, the performance of the blade is significantly improved:

Hardness improvementThe hardness of the blade has significantly increased, thereby extending its service life.

Enhanced wear resistanceAfter cryogenic treatment, the wear resistance of the blade is significantly enhanced, reducing the frequency of replacement and lowering production costs.

dimensional stabilityThe stability of the processed blade size has been improved, ensuring cutting accuracy.

（2） Cryogenic treatment of metal components

A certain machinery manufacturing enterprise uses the New Zhi'afus low-temperature freezer to perform cryogenic treatment on metal steel strips, molds, cutting tools, measuring tools, scissors, saw blades, etc. The processed components perform excellently:

Residual stress reliefCryogenic treatment effectively eliminates residual stresses generated during quenching, improving the dimensional stability and service life of components.

performance improvementThe hardness and wear resistance of the components have significantly improved, enhancing overall performance.

（3） Low temperature assembly process

At a certain automotive parts manufacturing enterprise, the New Zhi'afos low-temperature freezer is used for low-temperature assembly processes of automotive bearings and micro motor shafts. In low temperature environments, metal materials shrink, making assembly easier and improving assembly efficiency and accuracy.
