Design bigger, longer, heavier and more complex cold forged parts than ever before

Arconic Fastening Systems continues to develop its engineering expertise and capability at its St Cosme Operations and can now offer you and your engineering team the ability to design even bigger and more complex cold forged parts.

Key Advantages
Segment Open Die
Our new open die forging process gives you the opportunity to cold forge even more complex parts. This innovation allows part weight reduction as well as 'bone' shape parts.
Enhanced Range
From thin and light parts to large and heavy parts, our new cold forging capabilities give us the possibility to forge a greater range.
Bigger Cold Forged Parts
Our new generation forging press enables us to increase part size. We can now produce parts up to 165mm in length (previously 80mm), with a larger diameter now up to 54mm (against 48mm before). And heavier parts (up to 800g instead of 350g).
