Forged Hollows & Sleeves — Manufacturer & Supplier

Trepanned and mandrel forged hollows, sleeves, bushes and cylinder bodies with bore UT.

Hollow forgings replace a machined-from-solid part where the bore is large enough to be worth forging in. We trepan or mandrel forge the bore, which both saves the centre material and improves the soundness of the remaining wall, then heat treat and ultrasonically test from both the outside diameter and the bore. Typical parts are hydraulic cylinder bodies, bushes, sleeves, nozzles and valve bodies.

Manufactured under the Stancor Forgings brand by Stancor Forgings.
