Whether you have an exist­ing spring application in need of re-engineering or a new one that requires designing, check out Duer Carolina Coil‘s manufacturing guide.

“Coil Spring Manufacturing Technical Guide” is a must-read industry resource with insight on tolerances, formulas, stress correction, surface protection, and much more.

The engineering team and Duer Carolina Coil has been manufacturing springs for more than 100 years and has refined the coil spring manufacturing process for the industry — and for all types of coil springs.

The scope of the manual is limited to data, which will be helpful to the design engineer in solving problems frequently encountered in helical springs. General information, such as maxi­mum stress limits, relative costs of materials, and the more often used formulas are presented for references.

For the sophisticated engineer desiring more technical design information Duer Carolina Coil highly recommends Dr. A.M. Wahl’s “Mechani­cal  Springs,” which was published by the McGraw-Hill Company.
