Shrink fit
Encyclopedia
A shrink fit is an interference fit
achieved by a relative size change after assembly. This is usually achieved by heating or cooling one component before assembly and allowing it to return to the ambient temperature after assembly. A common industrial application is the induction shrink fitting
process. It may also be achieved by means of a phase transition; see shape memory coupling

Interference fit
An interference fit, also known as a press fit or friction fit, is a fastening between two parts which is achieved by friction after the parts are pushed together, rather than by any other means of fastening...

Induction shrink fitting
Induction shrink fitting refers to the use of induction heater technology to pre-heat metal components between and thereby causing them to expand and allow for the insertion or removal of another component. Typically the lower temperature range is used on metals such as aluminium and higher...

Shape memory coupling
Shape-memory coupling is a system for connecting pipes using shape-memory alloys. In its typical form the technique uses an internally ribbed sleeve of alloy such as Tinel that is slightly smaller in diameter than the pipes it is to connect...
