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.
