Magnetic Technologies Ltd offers
a variety of brakes for pay-offs and
take-ups. Its brakes are infinitely
adjustable to give extremely accurate
tension control, and come in numerous
sizes to fit customers’ spools and reels.
Torque is developed magnetically and
will remain the same year after year.
The torque range is 0.11" ounces to 320"
pounds. Advantages include adjustability,
portability, and a minimum of floor
space. Every brake or clutch is carefully
engineered to give exceptional long life,
for even the most demanding production
standards.
They are designed to be easily mounted
and serviced or modified, should the need
arise. Magnetic Technologies stocks spare
parts for all of its products and does any
necessary repairs in-house at the company’s
facility in Oxford, Massachusetts, USA.
Several models have tapered roller bearings
to support heavy overhung loads.
Howard Schwerdlin, sales manager, said:
“Based on our highly reliable electric
hysteresis brakes, we have developed a
constant current power supply controller
that uses an internal computer to
constantly adjust brake torque as the
supply spool diameter decreases during
pay-off using an ultrasonic probe to
measure spool diameter.”
“The controller incorporates the torque
vs current curves for all ten sizes of
brakes and logic to provide constant
current to the brake over time. Multiple
brakes can be controlled with one
power supply.
“With direct touch panel control, the
operator needs only to enter the desired
tension in either imperial or metric units.
Both individual single station or multiple
station designs are available.
“For applications that do not require
constant tension a variety of single to
multi-spool payoff stand types are also
available.”

Today, replacement of conventional wire
rod wet preparation by the PDH system
phosphate-free conversion coating
changes rapidly the current state of wire
drawing, generating lower operating cost
and benefitting from significant energy
and maintenance savings, and complete
environmentally friendly rod conversion
coating and wire lubrication process.
Users have been attracted by the PDH
coating technology, which is potentially
less complex, much cheaper, simpler and
more convenient to use.
The PDH system is used in-line in the
most demanding drawing applications
with all carbon steel rods and wires,
including 0.90%C , mechanically descaled
or acid cleaned, uncoated or pre-coated,
in applications including spring wire,
rope wire, PC strand wire, plating wire,
cold heading wire, galvanised wire, CO 2
welding wire, etc.
The PDH system achieves a unique
scenario in modern wire drawing
operations, making the process green,
dry, clean, instantaneous, self-controlled,
repeatable, in-line, and operating at
virtually zero energy consumption.
The major positive impact is immediate:
• Unlimited rod coating speed
• Frictionless drawing
• Output 2.2-4.9 tonnes per hour (from
5.5-13mm H/C uncoated rod)
• Minimal die wear (0.1-0.3 micron per
tonne)
• Replacement of phosphate, borax
and wet substitutes by a powder
compound
• Hard and consistent fully controlled
anti-friction coat that captures
abrasive particles eliminating
two-body abrasion wear (the most
destructive lubricant contaminant)
• Elimination of moisture, which is
the number one enemy in the wire
drawing process (the second most
destructive lubricant contaminant)
• Extremely compact unit, easy to
incorporate into existing operation
• Providing very smooth wire finish not
difficult to clean with water
