All dobinsons coil springs are hot wound and the hardening and tempering of our coil springs is completed by an extremely precise electronically controlled furnace to eliminate breakage and sagging. The spring is mounted in a jig to ensure the correct orientation during grinding and it is held against a rotating abrasive wheel until the desired degree of flatness is obtained. Whether you have an exist ing spring application in need of re engineering or a new one that requires design in g this guide will help.

And there are four kinds of cross section structure of the spring wire called au ur bu and bur respectively. The coil is now placed into our conveyor fed shot peener and rotated for 100 coverage. The coil springs are not exempt. The process of manufacturing springs with mechanical spring machinery to create springs by coiling winding or bending the spring wire into the shape of a specific spring.

The sma coil springs are fabricated using an automatic coil forming machine which is the same machine that is used for a conventional coil spring. The engineering team and duer carolina coil has been manufacturing springs for well over 100 years and has refined the coil spring manufacturing process for the industry for all types of coil springs. 2 p is the compression load α is the helical angle of the spring wire d is the diameter of the helical d o is the outside diameter of the spring wire d i is the inside diameter of the spring wire. It encompasses all types of springs.
