Roll forming is a high-speed production
process that converts a flat strip of metal into a finished or semi-finished
shape that is a channel, an
angle, a
tube, or a ring,
etc.
Roll forming typically competes with braking and extruding at lower volumes.
Roll form tooling is generally the most expensive tooling relative to these
competing processes, but the difference in tooling cost becomes moot as the
volume increases because the difference in per unit cost among these
processes decreases at an increasing rate.
This is not the only difference, however. Compared to brake forming, roll
forming can produce more parts with greater uniformity and consistency
throughout the length of the part. Roll forming also eliminates multiple
stage operations, trim scrap, and slitting burrs.
The same is true of the comparison between roll forming and aluminum
extruding. Other advantages of roll forming relative to extrusion methods
include: practically all metals can be roll formed, not just aluminum. Also,
roll forming can eliminate secondary operations - multiple stage operations
such as notching, punching, and post-painting - by combining in the roll
forming process. Pre-painted steel can be substituted for post-painting
methods and the metal can be perforated prior to roll forming or, if the
hole pattern is close to the beginning or end of the part, the formed part
can be perforated in the cut-off die. The ability to fabricate decorative
parts from pre-coated, pre-painted, or pre-plated metal is a distinct
feature of roll forming.
Samson Roll Formed Products Company is a contract roll former located in the
Chicago metropolitan area in a large industrial facility that houses 40 roll
forming lines and an array of ancillary equipment. Stamping, bending,
parting, and assembly are some of the other services in Samson's arsenal of
value added options.
 Samson
Roll Formed Products Company serves many industries including the Kitchen
and Bath industry. One of the roll formed parts that Samson makes for this
industry is a brass stanchion that is roll formed as a lockseam tube. The
perforations shown in the accompanying picture are post-punched rather than
pre-punched because they are close to the beginning and end of the part. The
part is subsequently chrome plated and sold as a kit with mating parts that
include end caps, double-sided tape, a plastic slide, and a showerhead. The
combination is sold as a premium portable hand-held shower assembly.
