SHRINK FITTING

SERVICE DESCRIPTION

Traditionally, when an interference fit is required, the fitting a component into another is either the force fit method or to expand the outer component with heat. Both these methods have disadvantages in that the former can lead to mechanical damage between the two faces and the latter can cause local damage or stress due to uneven or poor heating procedures, as well as the practicalities of heating large frames or housings.

Shrink fitting is the method of employing an cryogenic agent to shrink the shafts, tappets, or sockets, etc. so that fitting can be achieved that are far more cost effective than those achieved by heating the external components like gear wheels, housings, etc. .

Sometimes shrink fitting is the only possibility to connect different materials, which can not be cemented, welded or soldered.

In contrast to warm joining techniques, cold shrinking provides connections that do not warp. Metallurgical effects are reliably prevented. This process is applicable for components weighing from a few grams to several tonnes. Shrink fitting ensures that different material pairings (e.g. plastic and metal) are reliably and permanently joined
