Torque Master® - a success story

Since its launch in 1999, the Torque Master® has set the benchmark in PVC extrusion with the highest power density and best reliability. To date, no other manufacturer has succeeded in building a gear unit to deliver similar dependability and load capacity. Torque Master® has also courageously survived all endurance tests in the USA and has become established as the standard gear system for parallel counter-rotating twin-screw extruders.
