truck leaf spring

Products performance:
1.The function of springs is to bring the car shock absorption and increase its load so that the passengers feel more comfortable.
2.The camber can make the car move stable and anti-overturn.
3.The reasonable designing can prolong the life-span of the ridge beam,tyre and steel circle.
4.The raw material is SUP7 or more advanced steel,which makes our production reach the national(China) standard.
5.The accurate size for the spring makes its mechanism and engineering performance better.
6.Our technics is very exact.First we choose the raw material by analyzing its austenitic successive-transit cooling curve and then get the corresponding quenching solution which has various colling speed.Then we test the cooling curve in order to make the production under control in its manufacturing.

We hold some advanced equipments.The quenching machine is controlled by the PLC Computer which makes the heating treatment stable for the prouucts quality.And the stressing polishing machine for springs improves their anti-fagging ability and life-span.We use auto-spraying line and multi-work-spot assembly to improve the quality,capacity of the productions and reduce the working difficulty of the workers.We have perfect testing methods for metal phase,physical and chemical performance,rigidity and fagging.Those testing methods make all the productions under control in any time.

We have a huge capacity of 100,000 tons springs, 8000 tons U bolts and 2000 tons center bolts per year.
