Torsion testing machineis used for static torsion test. According to the product testing type torsion testing machine can be points for material machine for testing torsion, wire torsion testing machine and spring torsion testing machine 3 class, which material machine for testing torsion and divided into metal torsion test machine and non metallic materials torsion testing machine. Common type EZ-1/3/10/20/30 metal wire torsion testing machine, NDS and NDW CR-6 material testing machine, winding wire torsion testing machine. Widely used in welding, spring steel, steel wire rope, steel wire, wire, cable and other kinds of metal and non metal materials torsion test, can obtain maximum torque, torsional strength, yield strength and yield strength and other performance parameters.
