Below is a list of Industrial Springs manufacturers from New Britain, Connecticut. Industrial springs are helically shaped, strong mechanical devices used as components of machines, equipment and vehicles. While small springs are used in electronic and medical devices, industrial springs are much larger, although their functions are essentially the same. Thick pieces of round, flat or hollow wire are tightly wound with the application of heat to form a component with good elastic and return properties. When the spring's shape is changed, it exerts a resisting force and returns back to its original configuration.
