Wire Torsion and Spring Wire Tensile Testing Machine

Bench machine for tensile and torsion tests on spring steel wire from 0.5 to 6 mm. Used by wire drawers and spring makers to verify wire strength and ductility before coiling.

Specification

One head performs tensile tests with wire grips and a torsion test with rotating chucks until fracture. Twist count and tensile load are shown digitally, with the results compared to the wire standard.

Features

• Combined tensile and torsion operation
• Capstan-type wire grips
• Turn counter with fracture stop
• Variable speed
• Digital load display
