How about a crash course on the making of leaf springs?
There are many more steps involved than what is shown but this will give you a bit of insight to the manufacturing process.
The whole process starts with you. Orders are received by phone, fax, mail, emails and through the web |
If one of our 23,000 blueprints doesn't cover the springs needed, we will do the design work |
Manufacturing starts with shearing the steel SAE 5160 High Alloy Spring Steel is all we use 71 different sizes are kept in stock |
Steel is cut to the length called for on the blueprint |
To make a nice smooth riding spring the ends must be rolled tapered. After shearing, the ends are heated and run through offset rolls |
Once rolled and still hot the cup which holds the tip insert is formed in the end of the leaf |
Eyes are formed over the correct size mandrel |
Plates are heated to 1650 degrees then formed over patterns to the correct shape and arch |
After being heat treated the leaves are shot-peened to remove stress and lengthen its working life |
The next step is to install bushings and final assembly. Then off to the customer |
