Shrink Fitting refers to the use of induction heater technology to pre-heat metal components thereby causing them to expand and allow for the insertion or removal of another component. Metals typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed as a coefficient of thermal expansion. Exact temperature control is required to avoid unwanted metallurgical changes.

We will assist you in setting up a fast and repeatable method for expanding components for shrink fit. Bearings, couplings, gears, tool holders, collars , and many other components can be attached using the shrink fit method.
