EISCO LEAF SPRINGS PRODUCTION FLOW

Raw Material Shearing

Eisco factory leaf spring mass production process step 1:
Raw material was examined, then cutting the material into plates of fixed dimensions.

Hole Punching / Drilling

Eisco leaf spring factory mass production process step 2:
Making hole in the center, usually there are 2 methods, punching hole for common plates, while drilling hole for thick plates.

End Heating & Rolling

Eisco leaf spring factory mass production process step 3:
Strip processing was performed so that both end portions gradually formed a thin wall by heating the plate. Next, the parts, which will be wound, in both end portions of the plate, are machined in order that the width of the parts gradually decrease, and by winding the end portions after the heating.

Quenching & Bending & Hardening

Eisco leaf spring factory mass production process step 4:
Enter the quenching process,semiprocessed goods of leaf springs are formed in bent shapes after the heating, and are hardened by placing into a hardening tank.

Retempering of Leaf Springs

Eisco leaf spring factory mass production process step 5:
Tempering of leaf springs.After quenching, the strength and wear resistance of the steel plate can be improved, but the brittleness is also high. So, now Tempering can reduce the internal stress and hardness, making the steel plate have good elasticity and plasticity.

Lifting and Loading leaf springs

Eisco factory lifting and loadig leaf springs, to loading the finished goods and reay for shipment.
