In 1992, Feijele MFL Group launched the first multi-motor drawing machine using minimum slip control technology, completely changing the wire and cable industry. The machine was developed, manufactured and developed for many years under the Frigeco brand, an industry leader in wire drawing, stranding and extrusion lines.
The Frigeco Large Pull Machine is ideal for the production of copper, aluminum, bimetal and alloy wire rods.
The Frigeco Large Pull Machine is characterized by slip control technology. Instead of adding up the slip rate of each drum, each drum works at an actual slip rate of 1%, which conforms to the actual line speed of that drum. This is due to long-term experience in software management and driver programming, which ensures very high precision in motor speed control.
The entire machine management can be operated through recipes from the control panel, so the same settings can be retrieved every time the same diameter is produced.
The first pass was equipped with a small gearbox with high mechanical and thermal efficiency, allowing the machine to run without faults, improving motor power utilization, and improving machine efficiency.
The mold and drum are completely immersed in the coolant to prevent overheating, wire oxidation and surface problems. In addition, all annealed shafts are water-cooled.
The Frigeco Large Pull Machine uses a variable-frequency controlled AC motor that eliminates the need for filters, brushes, manifolds, belts, pulleys and joints. Most bearings do not require maintenance because they are designed to last the life of the machine. Ensure high-speed production operations without additional maintenance and maintenance.
DC annealing systems provide stable wire annealing, even during acceleration and deceleration, and as an option, Frigeco could propose gear switches to set the required voltage to save energy, in the same way as AC annealing furnaces.
These features of the large draw machine can save up to 20% energy, including minimizing slip rates during the final pass, eliminating unused blocks of the motor, air-cooled motors, and eliminating the need for re-commutation condenser.
