Roll forming or stamping for automotive parts?
Long constant sections, high-strength steels, volumes: when roll forming beats stamping for automotive parts, and when it does not.
Two different processes
Stamping forms a blank in a die, in one or several press strokes. Roll forming passes a strip through a series of roll stands that bend it progressively into a constant profile, then cuts it to length.
When roll forming wins
- Long parts with a constant or nearly constant cross-section: beams, rails, reinforcements.
- Very high-strength steels, which roll forming handles with good control of springback.
- High volumes, with continuous production and little scrap.
- In-line operations such as punching, cutting and inspection.
When stamping wins
- Complex 3D shapes, deep draws and variable sections.
- Body panels and parts with many features in several directions.
We do both
Because we build both stamping dies and roll forming lines, we recommend the process that fits your part, not the one we happen to sell. Contact us with your part data.
