Compression vs Extension Springs

Extension Springs

When it comes to understanding the difference between compression vs extension springs, look no further than the springs themselves. True, compression and extension springs have certain shared characteristics. For starters, both are easily recognizable by their familiar tightly wound, helical coils. Each is commonly made of spring steel or another non-ferrous metal. When a force… Read more »

Key Factors When Properly Manufacturing Springs

manufacturing springs

In manufacturing springs, a key performance indicator—one that may often be assumed if not taken for granted—is reliability. Whether a cell phone, a retractable pen, a garage door or a vehicle’s shock absorber, users expect that the spring in their application will work efficiently and consistently through innumerable cycles. An expectation perhaps, unreasonable or not,… Read more »

Corrosion Protection of Metal Springs


In the design and fabrication of a metal spring, corrosion protection is essential to ensure the application performs as required over its intended service life. The materials selected and the environmental conditions in which the application will function are prime design considerations to protect the spring from corrosion and its harmful effects on the metal… Read more »

4 Common Types of Metal Springs

Metal Springs

Though there are many types of metal springs engineered for products and applications, the majority of them are designed to serve one of 4 functions when a mechanical force is applied—compressive, tensile, torque, or counterbalance. As a result, it’s more than likely that designers and engineers will look for a custom solution with a compression,… Read more »

The History of the Slinky

Rainbow Slinky

The history of the Slinky, and its humble origin, is one of innovation, imagination, and perseverance as much as it is chance. Richard James, the founder of James Spring & Wire Company, invented the much-loved precompressed helical spring toy in 1943 while serving as a naval engineer at the William Cramp & Sons shipyards in… Read more »

5 Types of Specialty Springs & Their Common Uses


Specialty springs are custom-designed springs manufactured to fulfill a specific mechanical function in a particular mechanism. Specialty springs will vary in design in relation to the spring requirements and spring force—compressive, tensile, or torsion—needed for the application. Because specialty springs are uniquely designed for a specific application—they are not a stock item found on shelves—spring… Read more »

The Science of Springs & How They Work

Torsion Springs

How do springs work in real-world applications? For manufacturers, the answer to that question is directly related to understanding the science of springs. In doing so, manufacturers such James Spring & Wire Company can accurately predict exactly how its extension, compression, or torsion springs will function within a mechanical device or mechanism even before the… Read more »

Benefits and Applications of Helical Springs

Compression Springs

Helical springs are those familiar elastic coiled mechanical devices that are used to store and release energy. As a mechanical device, they are integral components for applications in nearly every industrial sector. The sheer amount of applications of helical spring in all areas of modern life is staggering.

The Evolution and History of Springs

Coil Springs

In the history of springs, it’s no exaggeration to state that spring technology has been around since the dawn of civilization. Look no further than the bow and arrow. One of the earliest applications of spring technology, the taut string of a bow has stored and released the mechanical energy required to provide food and… Read more »

How Coil Spring Manufacturing Works

Various Extension Springs

Coil spring manufacturing processes are used in the production of a variety of springs. The familiar shaped compression spring, extension spring, and torsion spring are all formed by coil manufacturing processes. Coiled springs are common elastic objects that store and release mechanical energy. They are manufactured, primarily, from various types of steel and produced in… Read more »
