Electromagnetic Sheet Metal Bending Brake - Magnabend
Magnabend offers performance characteristics no conventional
bending brake can match. The unique electromagnetic design of the keeper
clamping system allows you to form many complex shapes not possible
before. Plus, Magnabend can handle all regular shapes in light ferrous
and non-ferrous sheet metal (up to 4' wide, 18 ga.) in a simpler, less
time consuming and efficient manner.
The rugged simple construction of the Magnabend brake
has incorporating only one moving part assures low maintenance and versatility
for all light duty forming requirements.
A wide variety of complex shapes can be formed with Magnabend. These
include rolled edges up 330°, partial length bends, closed shapes,
unlimited depth for boxes and heavier material bends (up to 10 ga.)
in shorter widths.

Design Features Assure Quality
Simplicity is evident in Magnabend's electromagnetic brake design
which eliminates a conventional upper beam and more complex finger arrangements.
Keepers (clamping members) are simply positioned over the workpiece
and are clamped in place electromagnetically when the bending beam is
raised. Keepers self-adjust for material thickness as the apron moves.
- Electromagnetic Design Magnabend Designed to eliminate the hindrance
of an upper beam with the introduction of an elongated electromagnet
and keeper system.
- Self Locating A simple and effective method of locating the full
length keeper is achieved by spring-loaded steel locator balls.
- Triple Hinge System Three hinges allow Magnabend to have a lighter
bending beam without limiting durability and reliability.
- Bend-Angle Gauge Convenient bend angle gauge features adjustable
stop for precise, efficient repeat bends.
- Back Gauge Production efficiency in repeat bends is provided by
adjustable back gauge.
- Safety Features The safety button engages a light magnetic force
on the keeper. As well as a safety device, this force is a convenient
way to stabilize the work piece for precise measurement before you
activate full clamping power.
