Product Description
The Torsion and Wrapping Machine TW-691 is a reliable, precision-engineered testing instrument designed for the mechanical evaluation of metallic wires and conductors. Ideal for cable and wire manufacturers, quality control labs, and research units, this machine performs both torsion tests on steel wires up to 5 mm diameter and wrapping tests on aluminium conductors up to 6 mm diameter with exceptional accuracy.
Built with a motorized gearbox drive, the machine ensures smooth and consistent rotational movement during testing. The specially designed high-quality chuck set securely grips the wire, preventing any slippage during torsion or wrapping operations. A digital counter provides real-time twist or wrap measurements, while the auto-stop mechanism ensures immediate halt upon wire breakage, protecting both the specimen and the operator.
The TW-691 comes with a complete set of calibrated weights (1 kg to 20 kg) to meet various testing standards. Its heavy-duty powder-coated stand ensures stability, durability, and long-term performance in industrial environments.
Optimized for reliability, safety, and precise testing, the TW-691 is an essential tool for accurate mechanical testing of wires and conductors in modern manufacturing and laboratory settings.
