1. The metal wire torsion testing machine is suitable for measuring the plastic deformation resistance of metal wire with a diameter (or characteristic size) of 0.5mm-10mm in unidirectional or bidirectional torsion and displaying the defects on the surface and inside of the wire.
2. The winding testing machine is to tightly wind a sample with a diameter of 1-6mm on a mandrel for a specified number of spiral turns.
