Grotnes Shrinkers are used primarily to sizer parts requiring outside diameter accuracy.  The shrinking process is exactly the opposite of expanding.  The part is positioned in the shrinker, its outer diameter facing the shrinker tooling.  The dies are forced inward and press the metal part beyond its yield point and form its desired shape and size.  Grotnes Shrinkers are used in many applications such as pipe couplings, jet engine parts, drums, exhaust components, motor frames, conveyor pulleys, bearing races and similar parts.
