What is cryogenic assembly? Low temperature assembly is also called cold assembly (that is, cold shrinkage matching method), cold assembly is the use of refrigeration medium to cool the parts that need to be loaded in the base hole, so that its outline size shrinks, resulting in an assembly gap, so that the parts can be easily assembled.

Liquid nitrogen interference assembly has unique advantages

1. Large temperature control range

2. Small investment

3. Low temperature does not damage the workpiece, and is beneficial to the workpiece

4. Suitable for various workpiece assembly

5. Fast and good

6. Be efficient

Liquid nitrogen cooling assembly is suitable for the assembly of interference fit parts where the inclusion parts (such as planetary frames, torque arms, etc.) cannot be heated or the heating parts will cause the accuracy of the parts, the material organization changes, and affect their mechanical properties, and the inclusion parts (such as pins and elastic support shafts) can be frozen. Liquid nitrogen cold shrink assembly is suitable for all kinds of hot work mold, cold work mold assembly, gear and shaft assembly of all kinds of transmission, gear box, precision mechanical parts assembly, all kinds of motor stator, rotor assembly, automobile parts, engine parts.
