Configurations
Extension springs are helical springs designed to store energy and resist a pulling force. The spring used on a screen door is a good example of the most common type. At Spring Engineers, we understand the importance of proper attachment methods, offering a variety of end configurations including loops, hooks, threaded inserts, and swivels. The end configurations are unlimited but always perform the same basic function. The position of the ends can be random or can be designed with specific orientations to each other and to the spring body. Stresses present in the loops can be higher than those in the spring body. Calculation of these stresses is complex but it is a vital component for your final spring design as they can strongly affect performance, especially in cyclic applications.

Custom Extension Springs
During spring manufacturing, the springs are most commonly formed with a closed coil configuration, where each coil is in contact with the adjacent coil. The "initial tension" in the extension spring body determines how tightly these coils will be held together. Manipulating the initial tension during the design of custom extension springs will help achieve the desired load requirements for a given application. Stress considerations are important with any design of custom extension springs. The maximum recommended stress for extension springs with low initial tension requirements is easily calculated. Extension springs with high initial tension requirements cannot be adequately stress relieved and will require reductions in the maximum recommended stress. Sometimes special end hooks, swivel hooks, or plugs are used to improve the spring function. As an extension spring manufacturer, we can assist the client in the design of these features, as required by the application.
