What is Rollforming
The
process of cold roll-forming employs a series of pairs of matching
profiled rolls through which metal strip is passed without the
application of heat. Each pair of rolls progressively shapes the
metal until the final pair produce the required profile. The number
of pairs of rolls used in the production of a section usually
depends on the complexity of the profile.
Some quick facts about roll forming
Consistent Accuracy
Roll forming typically produces a more consistent and repeatable part than other forming methods.
Close Tolerances
A significant advantage of the Roll forming process is its ability
to maintain consistent close tolerances along a section.
Unlimited Lengths
Since Rollformers usually run from coiled material, product lengths
are limited only by the amount of material in the coil. Furthermore,
product lengths can be easily changed on-the-fly.
High Strength to Weight Ratio
In forming each bend the tensile strength of the metal in the
proximity of the bend is increased, and rigidity of the profile can
be further improved by incorporating additional ribs or bends.
Material Versatility
Ferrous and non-ferrous metals such as cold or hot rolled carbon
steel, stainless steel, aluminum, brass, copper, HSLA steel and even
titanium or special alloys can be rollformed
Pre-painted, galvanized, vinyl clad and plastic enclosed metals can
also be roll formed. By doing so, secondary coating operations can
be eliminated.
In-line Secondary Operations
Locating holes, “knock-outs”, and notches can all be punched in
the parts in-line before the finished parts are cut to length.
What Next?
To see if your product can be rollformed, just give us a drawing or
sketch of the part. From there, we’ll determine if it can be
practically rollformed. If so, we’ll also recommend which of our
popular standard machine is right for you. Even if a standard
machine won’t meet your needs, SEDVIK can also provide a custom
design to suit your requirements.
