-- Leaf Springs Manufacturing Process --

Step-1: By identifying your specific requirements, our sales department firstly picks up the appropriate specification sheet, which is then issued to the production team to proceed with the manufacturing process. We give a unique reference number to each specification sheet so that we can track the process all through the working life cycle of sundry item or spring.

Step – 2: Spring steel to BS970 is then cut off along the length and made to go through required operations incorporating eye-forming, nibbing, beating, taper-rolling and wrapping. Then, the leaves are heated up at temperature 1000 to 1, 0500 C, oil quenched in order to provide the temperature 8900C, or above. Once the draining is done, they are re heated at about 500 to 5600C so as to obtain the Brinell solidity reading of 356 to 440 HBS 10/3000, before the closing alterations are made to give adequate arc and shape.

Step – 3: When assembling the entire unit, the required components including center bolts, clips and bushes are added. The final unit manufactured is again evaluated against the specifications given in specs sheet. To complete the spring, it is coated with a protective covering, and then goes through final inspection according to quality control standards set by Leafsprings.co.uk.

Step – 4: The Locomotive Springs also implement the similar manufacturing course, but are made according to BR 148 and BR 166.
