We introduced manufacture experience of torsion bar from Italy and imported European advanced equipments.We adopt induction heat forging/hardening technology.In order to guarantee the quality of torsion bar,it is under the 100% quality inspection by the magnetic particle crack inspection and hardness & hardening depth-inspecting devices which were imported from Germany.Our products-automobile suspension torsion bar spring and cab torsion bar spring is not only situated in leading position in China,but also meet Italian technology standards.It has passed the new products appraisement by the"New Products Appraisement Committe"and awarded as the Third Class Awards of Automotive Industry Science and Technology Progress in 1998,and now we have successed in developing small torsion bar of power steering.
