Precision Forgings
Precision (near-net) forgings are closed-die forgings held to tighter tolerances with reduced draft and flash, so little or no machining is needed. They lower material use and machining cost for high-volume parts like gears, bevel gears and automotive components.
What it is
Tighter die control, accurate billet weights, controlled temperatures and sometimes flashless dies bring forgings very close to finished size. Some features, such as gear teeth, can be forged to near-final form.
Precision forgings suit high volumes where savings in material and machining outweigh the higher die and process cost.
Typical applications
- Bevel and spur gears
- Automotive transmission parts
- Constant-velocity joint components
- Turbine and aerospace parts
- Hand-tool and hardware components
Suitable materials
- Carbon steels (EN8, C45, 1045)
- Alloy steels (EN19, EN24, 42CrMo4, 20MnCr5)
- Stainless steels (304, 316, 410, 17-4 PH)
- Aluminium and titanium alloys
Points to consider
- Higher die cost; needs high volumes.
- Design with the forging supplier early to maximise near-net features.
- Material and billet weight control are critical.
- Final grinding may still be needed on bearing faces.
Frequently asked questions
What is a near-net forging?
A forging made so close to finished size that little or no machining is required.
What are the benefits of precision forging?
Less material, less machining and consistent strength, reducing total part cost at high volumes.
Can gear teeth be forged?
Yes. Bevel and some spur gears can be precision forged with teeth close to final form.
