  1. Njr-5 Wire Torsion and Wrapping Testing Machine

     
  2. Important function:
  • wire-simple, wire-reverse torsion test, wire-wrapping test, mandrel winding test.
  • wire-simple, wire-reverse torsion test, wrapping test and research for metal wire, bimetallic wire, composite material, bare wire, conductor of round and special section and so on.
  • used to determine the plastic deformation property and show surface and internal flaw of wire in wire-simple and wire-reverse torsion test.
  • the wire-simple torsion test for metal wire, copper, aluminum and theirs alloy, and composite materials with diameter of 0.1mm~5.0mm.
  • the wire-reverse torsion test for metal wire, copper, aluminum and theirs alloy, conductor of special section and composite material and so on with diameter of 0.1mm~5.0mm.
  • the wrapping test is suitable for metal wire, copper, aluminum and theirs alloy, conductor of special section, composite material and so on with diameter or thickness of 0.1mm~5.0mm.
  • the wire is wrapped around mandrel of specified diameter for specified circles to observe surface defect of wire.
  • repeated wrapping test or for one time.
  • zinc coating adhesiveness test.
  • torsion and wrapping in one machine.
