Cold Forging & Extrusion — Precision at High Volume
Cold forging forms metal at room temperature, giving parts a superior surface finish, tighter tolerance and higher strength through work hardening — at cycle times that make it the lowest-cost route for high-volume small and medium parts.
What Cold Forging Delivers
Because the metal is formed cold, there is no scale and no cooling distortion. You get better surface finish, tighter tolerance and work-hardened strength — and because it runs fast, the piece cost drops sharply as volume rises.
| Parameter | Typical capability |
|---|---|
| Materials | Low carbon steel, medium carbon steel, alloy steel, aluminium, copper |
| Part size | Small to medium — fasteners, pins, shafts, fittings |
| Dimensional tolerance | Tight; often machining-free on critical features |
| Surface finish | Excellent as-formed (no scale) |
| Key advantage | High volume, low piece cost, work-hardened strength |

FAQ
When is cold forging better than machining?
At high volume, cold forging beats machining on piece cost and material yield, and adds work-hardened strength. For low volume, machining is usually cheaper. We advise on the break-even volume for your part.
What tolerances can cold forging hold?
Tighter than hot forging and often machining-free on key features. We confirm achievable tolerance against your drawing.
Can you machine cold forged parts?
Yes, secondary machining is available where features cannot be formed.
