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.” 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

• 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 More information can be found on the Decalub website, and particularly on the newsletter pages on the site.

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 ▲ ▲ Rod phosphate-free conversion coating by PDH system

▲ ▲ A new constant current power supply controller has been developed by Magnetic Technologies

Both individual single station or multiple station designs are available.

“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.

“For applications that do not require constant tension a variety of single to multi-spool payoff stand types are also available.”
