Roll Forming Vs. Metal Stamping
Q: I am considering using metal stamping for component parts. How do I determine if another method, such as roll forming, could deliver better results?
A. Certain shapes are more suitable to metal stampings than roll forming. The differences are listed below:
- Most often, parts can be manufactured using either method. A more important consideration is the type of part. A long straight part is more suited for roll forming.
- The set-up cost for roll forming is usually less than metal stampings. If various part lengths are needed, the difference is great, metal stampings would require multiple set-ups. Roll forming various lengths is accomplished with a simple adjustment.
- Tool maintenance is less for a roll formed section than for metal stampings, only one set of tooling is required for parts of various lengths.
- Roll forming and most metal stampings can be produced using pre-plated or coated material.
