Shrink fitting

Shrink Fitting, or “compression fitting,” is a process that inserts a pin or bushing into a housing or other assembly requiring an extremely tight-tolerance fit. The shrink fitting process can be used as an alternative to conventional press fitting, or more likely, to permit a mechanical fit that otherwise could not be accomplished via the mechanical force of press fitting.

Material Separation

Cryogenic Material Separation uncouples parts by exploiting the different coefficient of thermal expansions (CTE) of products composed of different materials.
