The cold assembly process

Cold assembly  is a kind of assembly method that uses cooling medium to cool the parts which need to be installed in the base hole first, so as to shrink their dimensions and generate assembly clearance between the assembly surfaces, so as to facilitate the assembly of parts. Characteristics of cold charging process (1)It is… Read more The cold assembly process

The process of cold charging of industrial freezer

Determine whether the parts are suitable for cold assembly.Whether the physical properties, mechanical properties and metallographic structure of mechanical parts change abnormally at low temperature is the key to choose whether cold assembly can be adopted. The allowable cooling temperature shall be determined according to the change of various properties of the metallographic structure of… Read more The process of cold charging of industrial freezer
