Industry News & Employment Opportunities at Newcomb Spring
Newcomb Spring continually works to provide our customers with the latest news and developments related to the spring and metal form manufacturing industry. The following technical articles offer a variety of information including recent industry trends, new manufacturing techniques and in-depth information about engineering and design issues:
Permanent Set
Simply put, permanent set in a compression spring is a condition where the spring is deflected (compressed) and does not return to its original free length. This occurs when the material is deflected beyond its elastic properties... read full article

Modulus of Elasticity
Modulus of Elasticity is the measurement of stiffness and rigidity of spring material, or its elastic ability. The higher the value (modulus), the stiffer the material. Conversely, materials with lower values are more easily bent under load... read full article

How Spring Design Affects Costs
Often spring designs are more expensive and difficult to manufacture due to lack of space. Each type of spring presents its own challenges, however, adequate space for coils and spring diameters can simplify design and save cost when placed into production... read full article

Solid Height
The Solid Height of a compression spring is the height of the spring when all of the coils are brought together (stacked) by compression (load). The following formulas are used to calculate Solid Height for different end configurations... read full article

Active Coils in a Spring
The active coils are what make a spring a spring. We normally refer to the coils that open in an extension spring, the coils that deflect or close in a compression spring and the coils that twist or wind up/down in a torsion spring as "active"... read full article
