Cold Forming
What is this Vodo science and what are the benifits

While cold forming is closely associated with the manufacture of fasteners, the technique can be used to create an almost infinite array of custom designed parts. Cold forming is a high speed manufacturing process that causes metal to flow into a variety of shapes by applying forces greater than a metal's elastic limit.
By contrast, screw machine equipment removes metal by cutting, resulting in significant amounts of scrap, which adds to the total cost of manufacturing.

Lower Cost:

  • No Scrap.
  • Parts formed to near net shape with fewer secondary operations.
  • Multi-piece assemblies can be manufactured as a single component.
  • High speed production rates.

Greater Flexibility:

  • Process involves simplified tooling for fast turnaround
  • Create unique shapes, including parts with blind holes, through holes, extrusions and multiple diameters.
  • Large head to shank ratios possible without secondary machining.
  • Asymmetrical and eccentric body shapes.

Higher Quality:

  • Uninterrupted grain flow and work hardening improve material strength and reliability.
  • Finished surfaces are smoother than screw machined parts.

When should you consider the cold forming process?

  • When raw material costs are high.
  • When part reliability and strength are critical.
  • When production volumes are relatively high.
