Technical advantages of cold assembly  equipment 

    The lcold assembly  equipment   is mainly used for the low-temperature assembly of the workpiece. According to the principle of thermal expansion and contraction, the frozen workpiece shrinks by a certain amount, so as to achieve the purpose of assembly.
 

    Advantages of cold assembly  equipment :
 

    1. The cryogenic cold assembly  equipment  prevents the material from tempering again and reduces the product quality;

    2. Sometimes, the jacket cannot be heated, or the jacket is very large, at this time, only cold assembly can be used;

    3. At the same time of assembly, the parts were subjected to a cryogenic treatment to improve the dimensional stability of the parts, enhance the wear resistance, hardness, and product quality.

    4. The metallographic structure of the metal after cryogenic treatment is changed, and the performance is improved;

    5. After cryogenic treatment, the hardness, toughness, wear resistance and dimensional stability of the metal have been improved. The data shows that the dimensional stability of the mold is enhanced, the wear resistance of bearings and tools is improved, and the life is greatly improved.

    6. The residual austenite content in the metal material can be greatly reduced from 15% to 20% after heat treatment to less than 5%, so that the dimensional stability can be greatly improved. At the same time, the stability of the remaining austenite is also greatly improved, and it will rarely happen again.

     7. Precipitate the uniform, fine and dispersed carbonized material produced on the metal structure matrix. The appearance of this kind of carbonization will significantly improve the wear resistance and friction performance of the metal, and the hardness will also increase, which will directly increase the life of the wear parts.
