|
| Assembly |
Two
distinct parts can be run together to form one assembly. |
| |
|
| Clad Shapes |
Two
different materials can be formed simultaneously to produce a
clad shape in one operation. |
| |
|
| Energy
Efficiency |
Roll
forming is an energy efficient process usually requiring no
process heat to be added. |
| |
|
| Finish |
Roll
forming can produce superior surface finishes. Sharp, clean
contours can be maintained. The absence of die marks on the
material often eliminates the need for additional finishing. |
| |
|
| Hole and Slot
Patterns |
Pre-punching in-line allows holes or slots that cannot be done
as a secondary operation because of their location or features
of the part to be included in the shape. |
| |
|
| Hollow Shapes |
Hollow or semi-hollow shapes can be produced with thinner
walls than are possible by competing processes. |
| |
|
| Lengths |
Almost unlimited lengths can be roll formed. The only
limitations are due to material handling equipment, space
constraints, and shipping capabilities. |
| |
|
| Material |
Almost any bendable material can be roll formed. |
| |
|
| Production |
The
high speed, continuous nature of roll forming lends itself to
economic production of large volumes of parts. |
| |
|
| Secondary
Operations |
Many
additional operations, such as punching, notching, welding and
bending, that otherwise would have to be performed as
secondary operations can be incorporated into the roll forming
process, thus, reducing handling and processing costs. Even
labels giving installation instructions can be applied to the
shape as an in-line process. |
| |
|
| Structural
Applications |
Roll
formed materials generally have a strength advantage over
competing processes in structural rigidity applications. |
| |
|
| Tolerances |
Roll
forming can achieve closer tolerances than are possible with
most competing processes. |
| |
|
| Tooling |
The
same tooling can be used to roll a shape out of different
materials. |
| |
|
| Uniformity |
Roll
forming produces symmetrical parts with uniform dimensions
that assure precisions fits, simplify production, and that
speed assembly and minimize rejects. |
