Forging Parts
Shafts, flanges, hubs and gear blanks, forged for grain flow and finish-machined for accuracy.
What this process is
Forging Parts, in plain terms
Forging shapes hot steel by compression, and the result has a grain structure that follows the part rather than being cut across it. That is why forged shafts survive shock loading where a machined-from-plate equivalent fractures. We forge closed-die and open-die, heat-treat to specification, and finish-machine the features that need to be accurate.
When this is the right answer
- Shafts, spindles, flanges, hubs and gear blanks
- Parts subject to shock, impact or high cyclic load
- Components where grain flow determines the service life
The trade-off. Forging needs a die, so there is a setup cost. In exchange the part is stronger than anything machined from the same section, and the material utilisation is far better.
What we make
12 part families
Each family covers a shape and the way it is normally made. Open one for the materials, the processes and the typical applications behind it.
