5 Types of Specialty Springs & Their Common Uses

Surgery

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 »

What Is a Wire Form?

Various Wire Forms

Wire forms or, more specifically, wire forming, is a fabrication technique that utilizes blanks of metal wire which is manipulated into standard or customized shapes for a variety of applications. The wire is typically drawn from blank strips or coiled spools of flat or round wire, rolled and tempered, and then formed into different configurations… Read more »

Calculating a Spring Constant Using Hooke’s Law

Spring

Knowing how to calculate a spring constant is essential in the design and manufacture of springs. Before a spring is produced for an application, engineers need to know how the spring will behave and function to determine whether the design is suitable for the application.

How to Determine the Length for Constant-Force Springs

Constant-Force Spring

Constant-force springs are mechanical devices used in applications that typically require some kind of counterbalancing or retraction mechanism. In design and function, constant-force springs differ from the more common familiar types of wound springs. They exert a consistent linear force or torque that remains constant over a large range of motion.

Spiral Torsion Springs Manufacturing

Various Torsion Springs

Spiral torsion springs are mechanical devices that store and release mechanical energy through the exertion of rotational torque force. It is one of two basic torsion spring designs, the other being the more familiar helical or coiled torsion spring, the shape of which resembles the compression or extension spring, and operates in a radial direction… 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 »

Spring Deflection and How It’s Calculated

Spring Constant

When a spring takes a bounce, the bounce it takes is a result of the spring’s deflection. Spring deflection is the action or motion that results from the application or release of a load. It is the response to a force when it is applied or removed. Spring deflection is also known as spring travel,… 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 »
