in engine


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.


Packing detail  

Firstly, the crankshafts are coated the imported anti rust oil. The oil form a harden film which dont pollute your

Then they are wrapped with plastic bags.   

We have 3 kinds of outer package ( Foam packing, Moving luxury wooden case and Normal wooden case )  

Usually the foam packing=foam box+imported anti rust oil+ carton

Moving luxury wooden case=imported anti rust oil+plastics bag+wooden box(the thickness of the wooden box is 10mm)

Normal wooden case=anti rust paper+wooden box (the thickness of the foam box is 15-20mm)

And after all finishes the crankshafts are being packed with pallet.
