  • Reduces raw material waste – No Flash!
  • Low scrap rates -0- PPM rejections
  • Tight tolerances with forged centers if required
  • Excellent surface finish with no scale!
  • Utilize turned and polished bar – no decarb!
  • Improved physical properties by refining grain structure
  • Eliminates subsequent heat treating
  • Average press uptime = 94%
  • Forged in centers can eliminate end mill and center operations.

Why Cold Forging as a superior alternative to machining or hot upset forging?

  • Precision Cold forging offers near net production of parts at room temperature. Cold forging makes products precisely sized very close to the final shape. The mechanical deformation refines grain structure and breaks up and aligns any inclusions. The result is that the grain of the material lies parallel to formed surfaces rather than breaking through and providing opportunities for crack initiation as in machined parts.
  • The precision cold forging process combined with finish machining offers significant raw material savings and machining time vs. machining from bar stock or from a standard upset hot forged part. Cold forging provides consistent and more precise tolerances and maintains microstructure grain flow for better finish and durability.
  • Cold forging work hardens material and raises its yield stress. With strength and other mechanical properties improved thicknesses can be reduced and the resulting savings on weight and material are likely to be considerable.


  • Higher yield – stronger
  • Closed tolerances
  • Less machine stock
  • Fine surface finish with no scale
  • No draft – none!
  • Part to part uniformity – dimensional repeatability
  • Functional reliability
  • Excellent definition

No Cost – No Obligation

Whether you have an existing part or are designing a new component, our application engineers will determine if cold forming will benefit your application. Prior to any investment on your part samples will be provided and delivered based on your purchase order and must be approved by you prior to paying for tooling.
