product name :Metal Wire Torsion Testing Machine(economic type)
product specifications :EJJ series
 

EJJ-Series Metallic Wire Torsion Testing Machine

 

1 important function

1) Wire single direction torsion test: wire winded along axial direction for 360° is defined as one time of torsion, and torsion to specifed times until breaking.

2) Wire reverse torsion test: wire winded along axial direction for 360° is defined as one time of torsion, winded for same number of times along another direction until breaking.

3) Simple, reverse torsion and wrapping test and research with metallic wire, nonmetallic wire, compounding material, bare wire, round and special shape of cross section of conductor.

4) simple and reverse torsion test for plastic deformation and defect of surface and inner.

5) Test for shape of breaking point and defect(flat, ladder shape, skew, fan shape, with gap and shrinkage cavity ).

6) Check crack layer(there is continuous crack, flash and so on)

7) Simple torsion test with nominal diameter of 0.1mm -- 10.0mm metallic, copper, aluminium and its alloy, and compounding material.

8) Bidiection torsion test with nominal diameter of 0.1mm -- 10.0mm metallic, copper, aluminium and its alloy, special cross section conductor and compounding material.

 

2 Standard

1) Metallic materials -- Wire -- Simple torsion test

2) ISO 9649 Metallic materials -- Wire --Reverse torsion test

3) ISO 4101 Drawn steel wire for elevator ropes -- Specifications.
