Shrink fitting is called the union by mechanical interference of two pieces to form an integral assembly. This union is achieved through two main approaches:
The thermal shrink uses the phenomenon of expansion during the heating of materials, and contraction during the cooling thereof. This eliminates the mechanical interference with little or no pressure needed for assembly.
The thermal shrink is used in mechanical assembly and delicate parts where you can not apply mechanical pressure.
The main advantages of induction shrink fitting are the reduction of stresses and residual deformations and control capacity of union quality.
There are different forms of heating for thermal shrink such as gas, furnace and induction among others.
Induction heating is the preferred method for the thermal shrink process due to its ability to deliver rapid, localized, and consistent heat.
This targeted heating causes precise thermal expansion of the inner component, allowing for effortless assembly without mechanical force.
