Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

BJXN - 10 series metallic wire torsion testing machine is suitable for the determination of diameter 0.1 10.0 mm (or feature sizes) as the metal wire in the one-way or two-way torsion under plastic deformation ability, and show wire rod surface and internal defects.

It is suitable for measuring the plastic deformation of metal wires with a diameter (or feature size) of 0.1-10.0mm in one direction or two - way torsion and the defects in the surface and interior of the wire.

Metal wire torsion testing machine for standard GB/T 239.1 2012 of the People's Republic of China the first part of the metal material wire one-way torsion test method ", also apply to the international standard ISO 7800:2003 "metal wire one-way torsion test method" and the ISO 9649:1990 "metal wire two-way torsion test method".

Unidirectional torsion: the sample is rotated 360 degrees uniformly in a direction around its axis as a twist to the specified number or sample fracture.

Bidirectional torsion: the sample is rotated 360 degrees uniformly in one direction to the same direction as the specified number of times, and then rotated the same number or sample fracture in the opposite direction.
