Advantage of crankshaft
• The crankshaft hardness after induction hardening
• Continuous and homogeneous hardness
• High corrosion resistance
• More flexible structure
• High stress resistance
• High fatigue and shock resistance
• Suitable to work under friction and heavy loading pulse.
About quality control
We have passed quality control certification system of ISO9000,TS16949 which are main quality certificate.
Quality Control equipments include Spectrometer, Microscope, Durometers, Magnetic particle crack detectors,
Perfilometer, Roughness test machine, Residual stress inspection etc.applied on every production step.
HC Crankshafts are guaranteed for 12 months after arming in engine.If in this period the crankshaft is broken,
we will one compensable three.
